All financial amounts are adjusted for inflation using the Consumer Prices Index including owner occupiers’ housing costs (CPIH) excluding Council Tax, to their financial year ending March 2018. For example, the mean disposable income for those aged 35 and born in the 1970’s (£35,752) is estimated by taking the average (in real terms) of the household disposable income for these people across the combined dataset.",

The indicators are the percentage of one-person households, in which the householder is aged 65 years and over and the percentage of one-person households, in which the householder is aged 85 years and over. This dataset has been produced by the Ageing Analysis Team for inclusion in the subnational ageing tool, which was published on July 20, 2020 (see link in Related datasets). The tool is interactive, and users can compare latest and projected measures of ageing for up to four different areas through selection on a map or from a drop-down menu. Note on data availability: England, Wales, Scotland and Northern Ireland independently publish subnational household projections. Each country publishes a different set of age breakdowns and only England and Scotland provide the breakdowns required to calculate the indicators included above.",

The indicators are the projected percentage of the population aged 65 years and over, 85 years and over, 0 to 15 years, 16 to 64 years, 16 years to State Pension age, State Pension age and over, median age and the Old Age Dependency Ratio (the number of people of State Pension age per 1000 of those aged 16 years to below State Pension age). This dataset has been produced by the Ageing Analysis Team for inclusion in the subnational ageing tool, which was published on July 20, 2020 (see link in Related datasets). The tool is interactive, and users can compare latest and projected measures of ageing for up to four different areas through selection on a map or from a drop-down menu. Note on data sources: England, Wales, Scotland and Northern Ireland independently publish subnational population projections and the data available here are a compilation of these datasets. The ONS publish national level data for the UK, England, Wales and England & Wales, which has been included. National level data for Scotland and Northern Ireland have been taken from their subnational population projections datasets.",

The indicators are the projected sex ratio for those aged 65 years and over and the projected sex ratio for those aged 85 years and over. A sex ratio shows the number of males in the population for every 100 females. This dataset has been produced by the Ageing Analysis Team for inclusion in the subnational ageing tool, which was published on July 20, 2020 (see link in Related datasets). The tool is interactive, and users can compare latest and projected measures of ageing for up to four different areas through selection on a map or from a drop-down menu. Note on data sources: England, Wales, Scotland and Northern Ireland independently publish subnational population projections and the data available here are a compilation of these datasets. The ONS publish national level data for the UK, England, Wales and England & Wales, which has been included. National level data for Scotland and Northern Ireland have been taken from their subnational population projections datasets.",

          "*Rebasing of population estimates:* This dataset contains the population estimates for each country and local authority of the UK rebased to the results of the 2021/2022 censuses across the UK. These estimates replace previously published estimates for 2011 to 2022. *Usual residence definitions:* the estimated resident population of an area includes all those people who usually live there, regardless of nationality. Arriving international migrants are included in the usually resident population if they remain in the UK for at least a year. Emigrants are excluded if they remain outside the UK for at least a year. This is consistent with the United Nations definition of a long-term migrant. Armed forces stationed outside of the UK are excluded. Students are taken to be usually resident at their term time address. *Rounding:* estimates are presented unrounded. Unrounded estimates are published to enable and encourage further calculations and analysis. However, the estimates should not be taken to be accurate to the level of detail provided. More information on the accuracy of the estimates is available in the [Quality and Methodology document](https://www.ons.gov.uk/peoplepopulationandcommunity/populationandmigration/populationestimates/methodologies/midyearpopulationestimatesqmi). *Small counts:* the estimates are produced using a variety of data sources and statistical models, including some statistical disclosure control methods, and small estimates should not be taken to refer to particular individuals."

        "Geography is based upon the home postcode of the learner. From 2013/14 to 2017/18, Modern Apprenticeship (MA) data was reported by Scottish Vocational Qualification (SVQ) level (2, 3, 4 and 5). From 2018/19, SDS began to phase out reporting by SVQ level to instead report by the Scottish Credit and Qualifications Framework (SCQF) levels. Therefore from 2018/19, any data relating to MA starts is reported by SCQF level only, with residual data including both SVQ and SCQF levels. Please refer back to the Modern Apprenticeship Statistics [user guide](https://www.skillsdevelopmentscotland.co.uk/media/qp3jhkdz/modern-apprenticeship-user-guide.pdf) for more information. The [Scotland population time series data](https://www.nrscotland.gov.uk/publications/population-estimates-time-series-data/) is used to create a rate per 100,000 population and are currently available for the years up to mid-2024. Figures produced by each UK nation may differ due to differing sources, time periods, age analysed or differences in methodologies so they are not directly comparable."

          "Geography is based upon the home postcode of the learner. From 2013/14 to 2017/18, Modern Apprenticeship (MA) data was reported by Scottish Vocational Qualification (SVQ) level (2, 3, 4 and 5). From 2018/19, SDS began to phase out reporting by SVQ level to instead report by the Scottish Credit and Qualifications Framework (SCQF) levels. Therefore from 2018/19, any data relating to MA starts is reported by SCQF level only, with residual data including both SVQ and SCQF levels. Please refer back to the Modern Apprenticeship Statistics [user guide](https://www.skillsdevelopmentscotland.co.uk/media/qp3jhkdz/modern-apprenticeship-user-guide.pdf) for more information. The [Scotland population time series data](https://www.nrscotland.gov.uk/publications/population-estimates-time-series-data/) is used to create a rate per 100,000 population and are currently available for the years up to mid-2024. Figures produced by each UK nation may differ due to differing sources, time periods, age analysed or differences in methodologies so they are not directly comparable."

Regional estimates are compiled based on a combination of larger businesses reporting their R&D performing locations and smaller businesses having their data allocated to the location of their main business address held on the inter-departmental business register. Estimates produced at disaggregate levels such as region, product group and SIC may in some cases be subject to a high level of variability from year to year. This may be due to industry reclassification of some businesses and sampling variability."

Regional estimates are compiled based on a combination of larger businesses reporting their R&D performing locations and smaller businesses having their data allocated to the location of their main business address held on the inter-departmental business register. Estimates produced at disaggregate levels such as region, product group and SIC may in some cases be subject to a high level of variability from year to year. This may be due to industry reclassification of some businesses and sampling variability."

Some cancer groups are excluded from the indicator due to higher levels of missing stage at diagnosis data over the last three years (2020-2022). They were excluded on the basis that their inclusion would compromise the statistical robustness of the measure. The data source combines the Isles of Scilly totals with Cornwall to prevent potential disclosure of individuals.

Some cancer groups are excluded from the indicator due to higher levels of missing stage at diagnosis data over the last three years (2020-2022). They were excluded on the basis that their inclusion would compromise the statistical robustness of the measure.

        "Healthy life expectancy is a summary measure of health that adds a quality dimension to estimates of life expectancy by dividing expected lifespan into time spent in different states of health. Healthy life expectancy measures health-related wellbeing and represents the average time an individual is expected to live in \"very good\" or \"good\" general health, based on how individuals perceive their general health. The estimates in this indicator have been produced using an interim methodological fix. The decline in sample size of the Annual Population Survey has impaired our ability to continue using the previous method to estimate age-specific prevalence of \"good\" general health by local authority. We therefore used logistic regression to estimate \"good\" health prevalence instead of using the survey's observed prevalence. This enables continuity in local area reporting with a viable, comparable time series. ONS is currently conducting a review of data sources to assess their future potential to provide robust, reliable and durable measures of health status. Figures are based on the number of deaths registered, mid-year population estimates, and health state prevalence aggregated over three consecutive years. Figures exclude deaths of non-residents. Estimates for Isles of Scilly and City of London are excluded because of insufficient population counts. Estimates for Northern Ireland’s local government districts are available only from 2014 to 2016 onward. These estimates of healthy life expectancy in Northern Ireland use different methods and data sources compared to those produced by the Northern Ireland Department of Health; please see their [Health inequalities annual report](https://www.health-ni.gov.uk/news/health-inequalities-annual-report-2025) for more information. More quality and methodology information on strengths, limitations, appropriate uses, and how the data were created is available in the [Health state life expectancies, UK quality and methodology information (QMI) report](https://www.ons.gov.uk/peoplepopulationandcommunity/healthandsocialcare/healthandlifeexpectancies/methodologies/healthstatelifeexpectanciesukqmi2020to2022)."

          "Healthy life expectancy is a summary measure of health that adds a quality dimension to estimates of life expectancy by dividing expected lifespan into time spent in different states of health. Healthy life expectancy measures health-related wellbeing and represents the average time an individual is expected to live in \"very good\" or \"good\" general health, based on how individuals perceive their general health. The estimates in this indicator have been produced using an interim methodological fix. The decline in sample size of the Annual Population Survey has impaired our ability to continue using the previous method to estimate age-specific prevalence of \"good\" general health by local authority. We therefore used logistic regression to estimate \"good\" health prevalence instead of using the survey's observed prevalence. This enables continuity in local area reporting with a viable, comparable time series. ONS is currently conducting a review of data sources to assess their future potential to provide robust, reliable and durable measures of health status. Figures are based on the number of deaths registered, mid-year population estimates, and health state prevalence aggregated over three consecutive years. Figures exclude deaths of non-residents. Estimates for Isles of Scilly and City of London are excluded because of insufficient population counts. Estimates for Northern Ireland’s local government districts are available only from 2014 to 2016 onward. These estimates of healthy life expectancy in Northern Ireland use different methods and data sources compared to those produced by the Northern Ireland Department of Health; please see their [Health inequalities annual report](https://www.health-ni.gov.uk/news/health-inequalities-annual-report-2025) for more information. More quality and methodology information on strengths, limitations, appropriate uses, and how the data were created is available in the [Health state life expectancies, UK quality and methodology information (QMI) report](https://www.ons.gov.uk/peoplepopulationandcommunity/healthandsocialcare/healthandlifeexpectancies/methodologies/healthstatelifeexpectanciesukqmi2020to2022)."

        "Foreign direct investment (FDI) is cross-border investment made with the objective of establishing a lasting interest in the host economy. FDI is also defined by control relationships, where the direct investor (parent company) controls at least 10% of the voting power (ordinary shares) of the direct investment enterprise. These relationships can be measured in two directions: - outward: the direct investments of UK-resident companies in other countries. - inward: the direct investments in the UK from non-resident companies. Several factors affected FDI statistics for 2020. This not only includes disruption from the coronavirus (COVID-19) pandemic and global recession, but also some changes to the FDI statistical populations and sampling methods. We advise caution when comparing results for 2020 with earlier years. More detail can be found in [Foreign direct investment statistics, overview of methods changes: 2020](https://www.ons.gov.uk/economy/nationalaccounts/balanceofpayments/articles/foreigndirectinvestmentstatisticsoverviewofmethodschanges/2020)."

          "Foreign direct investment (FDI) is cross-border investment made with the objective of establishing a lasting interest in the host economy. FDI is also defined by control relationships, where the direct investor (parent company) controls at least 10% of the voting power (ordinary shares) of the direct investment enterprise. These relationships can be measured in two directions: - outward: the direct investments of UK-resident companies in other countries. - inward: the direct investments in the UK from non-resident companies. Several factors affected FDI statistics for 2020. This not only includes disruption from the coronavirus (COVID-19) pandemic and global recession, but also some changes to the FDI statistical populations and sampling methods. We advise caution when comparing results for 2020 with earlier years. More detail can be found in [Foreign direct investment statistics, overview of methods changes: 2020](https://www.ons.gov.uk/economy/nationalaccounts/balanceofpayments/articles/foreigndirectinvestmentstatisticsoverviewofmethodschanges/2020)."

        "Healthy life expectancy is a summary measure of health that adds a quality dimension to estimates of life expectancy by dividing expected lifespan into time spent in different states of health. Healthy life expectancy measures health-related wellbeing and represents the average time an individual is expected to live in \"very good\" or \"good\" general health, based on how individuals perceive their general health. The estimates in this indicator have been produced using an interim methodological fix. The decline in sample size of the Annual Population Survey has impaired our ability to continue using the previous method to estimate age-specific prevalence of \"good\" general health by local authority. We therefore used logistic regression to estimate \"good\" health prevalence instead of using the survey's observed prevalence. This enables continuity in local area reporting with a viable, comparable time series. ONS is currently conducting a review of data sources to assess their future potential to provide robust, reliable and durable measures of health status. Figures are based on the number of deaths registered, mid-year population estimates, and health state prevalence aggregated over three consecutive years. Figures exclude deaths of non-residents. Estimates for Isles of Scilly and City of London are excluded because of insufficient population counts. Estimates for Northern Ireland’s local government districts are available only from 2014 to 2016 onward. These estimates of healthy life expectancy in Northern Ireland use different methods and data sources compared to those produced by the Northern Ireland Department of Health; please see their [Health inequalities annual report](https://www.health-ni.gov.uk/news/health-inequalities-annual-report-2025) for more information. More quality and methodology information on strengths, limitations, appropriate uses, and how the data were created is available in the [Health state life expectancies, UK quality and methodology information (QMI) report](https://www.ons.gov.uk/peoplepopulationandcommunity/healthandsocialcare/healthandlifeexpectancies/methodologies/healthstatelifeexpectanciesukqmi2020to2022)."

          "Healthy life expectancy is a summary measure of health that adds a quality dimension to estimates of life expectancy by dividing expected lifespan into time spent in different states of health. Healthy life expectancy measures health-related wellbeing and represents the average time an individual is expected to live in \"very good\" or \"good\" general health, based on how individuals perceive their general health. The estimates in this indicator have been produced using an interim methodological fix. The decline in sample size of the Annual Population Survey has impaired our ability to continue using the previous method to estimate age-specific prevalence of \"good\" general health by local authority. We therefore used logistic regression to estimate \"good\" health prevalence instead of using the survey's observed prevalence. This enables continuity in local area reporting with a viable, comparable time series. ONS is currently conducting a review of data sources to assess their future potential to provide robust, reliable and durable measures of health status. Figures are based on the number of deaths registered, mid-year population estimates, and health state prevalence aggregated over three consecutive years. Figures exclude deaths of non-residents. Estimates for Isles of Scilly and City of London are excluded because of insufficient population counts. Estimates for Northern Ireland’s local government districts are available only from 2014 to 2016 onward. These estimates of healthy life expectancy in Northern Ireland use different methods and data sources compared to those produced by the Northern Ireland Department of Health; please see their [Health inequalities annual report](https://www.health-ni.gov.uk/news/health-inequalities-annual-report-2025) for more information. More quality and methodology information on strengths, limitations, appropriate uses, and how the data were created is available in the [Health state life expectancies, UK quality and methodology information (QMI) report](https://www.ons.gov.uk/peoplepopulationandcommunity/healthandsocialcare/healthandlifeexpectancies/methodologies/healthstatelifeexpectanciesukqmi2020to2022)."

This refers to properties in the Valuation List which are used for the purposes of a private dwelling. This excludes caravans, domestic garages, domestic stores and car parking spaces. Private refers to a self-contained dwelling and not the ownership or build type of the dwelling. Housing Stock includes both social sector and private sector dwellings in the Valuation List. Figures produced by each UK nation may differ due to differing sources, time periods, age analysed or differences in methodologies so they are not directly comparable."

          "In line with The Rates (Northern Ireland) Order 1977, Housing Stock is defined as a count of properties which are valued as domestic or mixed for the purposes of rating. This refers to properties in the Valuation List which are used for the purposes of a private dwelling. This excludes caravans, domestic garages, domestic stores and car parking spaces. Private refers to a self-contained dwelling and not the ownership or build type of the dwelling. Housing Stock includes both social sector and private sector dwellings in the Valuation List. Figures produced by each UK nation may differ due to differing sources, time periods, age analysed or differences in methodologies so they are not directly comparable."

        "Foreign direct investment (FDI) is cross-border investment made with the objective of establishing a lasting interest in the host economy. FDI is also defined by control relationships, where the direct investor (parent company) controls at least 10% of the voting power (ordinary shares) of the direct investment enterprise. These relationships can be measured in two directions: - outward: the direct investments of UK-resident companies in other countries. - inward: the direct investments in the UK from non-resident companies. Several factors affected FDI statistics for 2020. This not only includes disruption from the coronavirus (COVID-19) pandemic and global recession, but also some changes to the FDI statistical populations and sampling methods. We advise caution when comparing results for 2020 with earlier years. More detail can be found in [Foreign direct investment statistics, overview of methods changes: 2020](https://www.ons.gov.uk/economy/nationalaccounts/balanceofpayments/articles/foreigndirectinvestmentstatisticsoverviewofmethodschanges/2020)."

          "Foreign direct investment (FDI) is cross-border investment made with the objective of establishing a lasting interest in the host economy. FDI is also defined by control relationships, where the direct investor (parent company) controls at least 10% of the voting power (ordinary shares) of the direct investment enterprise. These relationships can be measured in two directions: - outward: the direct investments of UK-resident companies in other countries. - inward: the direct investments in the UK from non-resident companies. Several factors affected FDI statistics for 2020. This not only includes disruption from the coronavirus (COVID-19) pandemic and global recession, but also some changes to the FDI statistical populations and sampling methods. We advise caution when comparing results for 2020 with earlier years. More detail can be found in [Foreign direct investment statistics, overview of methods changes: 2020](https://www.ons.gov.uk/economy/nationalaccounts/balanceofpayments/articles/foreigndirectinvestmentstatisticsoverviewofmethodschanges/2020)."

Due to the disruption caused by the impact of COVID during the 2020/21 and 2021/22 academic years, caution should be taken when comparing data to previous years.

Persistent absence figures for all pupils and free school meals (FSM) are taken from the national absence figures and are produced using a different methodology based on enrolments and the school type is allocated in a different way so it is not appropriate to compare these figures with those for looked after children. Due to the disruption caused by the impact of COVID during the 2020/21 and 2021/22 academic years, caution should be taken when comparing data to previous years.

More details on the ONS Census disclosure control strategy may be found on the http://www.ons.gov.uk/ons/guide-method/census/2011/census-data/2011-census-prospectus/new-developments-for-2011-census-results/statistical-disclosure-control/index.html[Statistical Disclosure Control] page on the ONS web site."

More details on the ONS Census disclosure control strategy may be found on the http://www.ons.gov.uk/ons/guide-method/census/2011/census-data/2011-census-prospectus/new-developments-for-2011-census-results/statistical-disclosure-control/index.html[Statistical Disclosure Control] page on the ONS web site."

More details on the ONS Census disclosure control strategy may be found on the http://www.ons.gov.uk/ons/guide-method/census/2011/census-data/2011-census-prospectus/new-developments-for-2011-census-results/statistical-disclosure-control/index.html[Statistical Disclosure Control] page on the ONS web site."

        "For the UK House Price Index (UK HPI), the standard average house price is calculated by taking the average (geometric mean) price in January 2015 and then recalculating it in accordance with the index change back in time and forward to the present day. The geometric mean reduces the weighting given to high value properties when compared to the arithmetic mean and is typically lower, usually closer to that of the median. Estimates for the most recent months are provisional and are likely to be updated as more data is incorporated into the index. Read [Revisions to the UK HPI data](https://www.gov.uk/government/publications/about-the-uk-house-price-index/about-the-uk-house-price-index#monthly-revision). The UK House Price Index (UK HPI) is calculated by the Office for National Statistics and Land & Property Services Northern Ireland. Find out about the [methodology used](https://www.gov.uk/government/publications/about-the-uk-house-price-index/quality-and-methodology#methods-used-to-produce-the-uk-hpi) to create the UK HPI.

          "For the UK House Price Index (UK HPI), the standard average house price is calculated by taking the average (geometric mean) price in January 2015 and then recalculating it in accordance with the index change back in time and forward to the present day. The geometric mean reduces the weighting given to high value properties when compared to the arithmetic mean and is typically lower, usually closer to that of the median. Estimates for the most recent months are provisional and are likely to be updated as more data is incorporated into the index. Read [Revisions to the UK HPI data](https://www.gov.uk/government/publications/about-the-uk-house-price-index/about-the-uk-house-price-index#monthly-revision). The UK House Price Index (UK HPI) is calculated by the Office for National Statistics and Land & Property Services Northern Ireland. Find out about the [methodology used](https://www.gov.uk/government/publications/about-the-uk-house-price-index/quality-and-methodology#methods-used-to-produce-the-uk-hpi) to create the UK HPI.

Average length of stay is calculated by dividing the number of nights by the number of stays. The data have a strong seasonal trend. Therefore, changes over time should generally be compared year-on-year, rather than month-on-month or quarter-on-quarter. While these statistics are believed to cover a large proportion of short-term lets activity in the UK, they do not cover all activity, as data from other providers and platforms are not included."

        "A household is in relative low income if they have less than 60% of the income of the average (median) household in the UK in a particular year. An annual survey of around 20,000 households estimates how many children (in the UK) live in households with an income below this level. Administrative data on benefits and earnings is then used to estimate how many children for the UK wide estimate live in each local authority in the UK. Figures are provisional and may be subject to revision in subsequent releases. Rates (presented as percentages) have been derived by dividing the number of children aged 0 to 15 living in low income families by the total number of children aged 0 to 15. Population figures are sourced from the mid‑2024 population estimates. Further information is available in the [Background information and methodology for Children in low income families: local area statistics](https://www.gov.uk/government/publications/children-in-low-income-families-local-area-statistics-background-information-and-methodology/background-information-and-methodology-children-in-low-income-families-local-area-statistics).

          "A household is in relative low income if they have less than 60% of the income of the average (median) household in the UK in a particular year. An annual survey of around 20,000 households estimates how many children (in the UK) live in households with an income below this level. Administrative data on benefits and earnings is then used to estimate how many children for the UK wide estimate live in each local authority in the UK. Figures are provisional and may be subject to revision in subsequent releases. Rates (presented as percentages) have been derived by dividing the number of children aged 0 to 15 living in low income families by the total number of children aged 0 to 15. Population figures are sourced from the mid‑2024 population estimates. Further information is available in the [Background information and methodology for Children in low income families: local area statistics](https://www.gov.uk/government/publications/children-in-low-income-families-local-area-statistics-background-information-and-methodology/background-information-and-methodology-children-in-low-income-families-local-area-statistics).

        "Current smoker estimates for each local authority can vary a lot from year to year because of small sample sizes. So, this indicator has moved to a five-year average to give a clearer picture of how smoking prevalence varies between local authority areas, rather than focusing on one year's figures. The averages presented are five-year averages, calculated using data from 2019 to 2023 and 2020 to 2024, where available. The five-year estimates have ranges of uncertainty (confidence intervals), which can be displayed by selecting the ‘Options’ button next to the bar and line charts. North Northamptonshire and West Northamptonshire averages are based on a 3-year average (2022 to 2024), because of boundary changes. City of London and Buckinghamshire Unitary Authority averages are based on a 4-year average (2021 to 2024), because of boundary changes. Due to minor boundary changes in 2024, Local Authority codes were updated for Barnsley and Sheffield. Barnsley changed from E08000016 to E08000038, and Sheffield changed from E08000019 to E08000039. These changes did not affect comparability. To account for the discontinuity caused by the move to telephone-only interviewing in 2020, a weighting adjustment was introduced for APS data from 2020 to 2023. A single factor was applied to the existing APS weights to give an adjusted weight, which reduced the discontinuity effect caused by the change in method of data collection. For the 2024 release, a revised weighting approach was developed, applying separate scaling factors for each year, reflecting the return to mixed mode (face-to-face and telephone) interviewing at the end of 2023. Estimates from 2020 to 2023 have been revised to reflect the updated approach. The weighting approach has not been applied to 2024 estimates because of the return to mixed mode interviewing.

          "Current smoker estimates for each local authority can vary a lot from year to year because of small sample sizes. So, this indicator has moved to a five-year average to give a clearer picture of how smoking prevalence varies between local authority areas, rather than focusing on one year's figures. The averages presented are five-year averages, calculated using data from 2019 to 2023 and 2020 to 2024, where available. The five-year estimates have ranges of uncertainty (confidence intervals), which can be displayed by selecting the ‘Options’ button next to the bar and line charts. North Northamptonshire and West Northamptonshire averages are based on a 3-year average (2022 to 2024), because of boundary changes. City of London and Buckinghamshire Unitary Authority averages are based on a 4-year average (2021 to 2024), because of boundary changes. Due to minor boundary changes in 2024, Local Authority codes were updated for Barnsley and Sheffield. Barnsley changed from E08000016 to E08000038, and Sheffield changed from E08000019 to E08000039. These changes did not affect comparability. To account for the discontinuity caused by the move to telephone-only interviewing in 2020, a weighting adjustment was introduced for APS data from 2020 to 2023. A single factor was applied to the existing APS weights to give an adjusted weight, which reduced the discontinuity effect caused by the change in method of data collection. For the 2024 release, a revised weighting approach was developed, applying separate scaling factors for each year, reflecting the return to mixed mode (face-to-face and telephone) interviewing at the end of 2023. Estimates from 2020 to 2023 have been revised to reflect the updated approach. The weighting approach has not been applied to 2024 estimates because of the return to mixed mode interviewing.

        "Proportions of people claiming are the number of claimants in a year divided by the population aged from 16 to 64 from mid-year 2023 population estimates. The experimental Claimant Count consists of claimants of Jobseekers Allowance (JSA) and some Universal Credit (UC) Claimants. The UC claimants that are included are 1) those that were recorded as not in employment (May 2013-April 2015), and 2) those claimants of Universal Credit who are required to search for work, i.e. within the Searching for Work conditionality regime as defined by the Department for Work & Pensions (from April 2015 onwards). The count is based on live claims on the second Thursday of the reference month. Under certain circumstances, some people are able to claim both contribution-based JSA and UC at the same time. Consequently, there has been a small amount of double counting. Information from DWP suggests this double counting increased at the start of the pandemic and has stabilised at approximately 1.0 to 1.5% of the Claimant Count. Northern Ireland local government districts Claimant Count figures are only available from 2013 onwards."

The experimental Claimant Count consists of claimants of Jobseekers Allowance (JSA) and some Universal Credit (UC) Claimants. The UC claimants that are included are 1) those that were recorded as not in employment (May 2013-April 2015), and 2) those claimants of Universal Credit who are required to search for work, i.e. within the Searching for Work conditionality regime as defined by the Department for Work & Pensions (from April 2015 onwards). The count is based on live claims on the second Thursday of the reference month. Under certain circumstances, some people are able to claim both contribution-based JSA and UC at the same time. Consequently, there has been a small amount of double counting.

          "Early years foundation stage profile was revised significantly in September 2021. It is therefore not possible to directly compare assessment outcomes from 2021/22 onwards with earlier years. Results are published by DfE and there are some differences between the results broken down by upper tier local authorities (based on the location of the submitting authority) and those by lower tier local authorities (based on the postcode of the school or provider). For more information, please refer to [Early years foundation stage profile results Methodology](https://explore-education-statistics.service.gov.uk/methodology/early-years-foundation-stage-profile-results-methodology). Some of this data has been aggregated and may show differences to other published figures."

Population is the sum of employed plus unemployed plus inactive. The ongoing challenges with response rates, response levels and weighting approach mean that labour market statistics based on both the Labour Force Survey (LFS) and Annual Population Survey (APS) will be considered [official statistics in development](https://osr.statisticsauthority.gov.uk/policies/official-statistics-policies/official-statistics-in-development/) until further review. Because of increased volatility of LFS and APS estimates, estimates of change should be treated with additional caution. Updates to this indicator have been temporarily suspended until the APS reweighting is implemented in 2026."

Population is the sum of employed plus unemployed plus inactive. The ongoing challenges with response rates, response levels and weighting approach mean that labour market statistics based on both the Labour Force Survey (LFS) and Annual Population Survey (APS) will be considered [official statistics in development](https://osr.statisticsauthority.gov.uk/policies/official-statistics-policies/official-statistics-in-development/) until further review. Because of increased volatility of LFS and APS estimates, estimates of change should be treated with additional caution.

The ongoing challenges with response rates, response levels and weighting approach mean that labour market statistics based on both the Labour Force Survey (LFS) and Annual Population Survey (APS) will be considered [official statistics in development](https://osr.statisticsauthority.gov.uk/policies/official-statistics-policies/official-statistics-in-development/) until further review. Because of increased volatility of LFS and APS estimates, estimates of change should be treated with additional caution. Updates to this indicator have been temporarily suspended until the APS reweighting is implemented in 2026."

Population is the sum of employed plus unemployed plus inactive. The ongoing challenges with response rates, response levels and weighting approach mean that labour market statistics based on both the Labour Force Survey (LFS) and Annual Population Survey (APS) will be considered [official statistics in development](https://osr.statisticsauthority.gov.uk/policies/official-statistics-policies/official-statistics-in-development/) until further review. Because of increased volatility of LFS and APS estimates, estimates of change should be treated with additional caution. Updates to this indicator have been temporarily suspended until the APS reweighting is implemented in 2026."

        "Mortgage Product Sales Data (PSD001) is regulatory data reported to the Financial Conduct Authority (FCA) by regulated mortgage lenders. This data reflects the number of mortgages taken out by first-time buyers, either individually or jointly, but does not include first-time buyers who purchased a property without a mortgage. The first-time buyer indicator in the FCA data is reported by the mortgage providers and its definition may vary across firms. For example, for individuals who are not remortgaging but have previously owned a property may or may not be counted as first-time buyers. Additionally, if a mortgage is taken out jointly by one first-time buyer and one non-first-time buyer, it may or may not be counted as a first-time buyer. The dwelling stock estimates used are published by MHCLG, Welsh Government, Scottish Government and the Northern Ireland Department of Finance. Some of this data has been aggregated and may differ from other published figures. Data for the Isles of Scilly is unavailable for all years due to low counts. Mortgage sales for Isles of Scilly have been excluded from aggregated areas that would normally include data from this area."

          "Mortgage Product Sales Data (PSD001) is regulatory data reported to the Financial Conduct Authority (FCA) by regulated mortgage lenders. This data reflects the number of mortgages taken out by first-time buyers, either individually or jointly, but does not include first-time buyers who purchased a property without a mortgage. The first-time buyer indicator in the FCA data is reported by the mortgage providers and its definition may vary across firms. For example, for individuals who are not remortgaging but have previously owned a property may or may not be counted as first-time buyers. Additionally, if a mortgage is taken out jointly by one first-time buyer and one non-first-time buyer, it may or may not be counted as a first-time buyer. The dwelling stock estimates used are published by MHCLG, Welsh Government, Scottish Government and the Northern Ireland Department of Finance. Some of this data has been aggregated and may differ from other published figures. Data for the Isles of Scilly is unavailable for all years due to low counts. Mortgage sales for Isles of Scilly have been excluded from aggregated areas that would normally include data from this area."

        "A business is deemed to have survived for five years if it is active in terms of employment and/or turnover at any point during the fifth calendar year following its year of birth. The five‑year business survival rate is calculated as the number of businesses that survive for five years as a proportion of businesses born in the start year. Some areas are affected by large numbers of businesses registering or de-registering at the same postcode (such as virtual offices, company formation agents, or foreign online sellers), which can distort local survival rates. The [Multiple Business Registrations methodology paper](https://www.ons.gov.uk/businessindustryandtrade/business/activitysizeandlocation/articles/multiplebusinessregistrationsatasinglepostcodeuk/latest) explains this and provides tables identifying postcodes with 500 or more business births or deaths. These registrations cannot be removed from the Business Register, but users may wish to consider their impact when interpreting local figures."

          "A business is deemed to have survived for five years if it is active in terms of employment and/or turnover at any point during the fifth calendar year following its year of birth. The five‑year business survival rate is calculated as the number of businesses that survive for five years as a proportion of businesses born in the start year. Some areas are affected by large numbers of businesses registering or de-registering at the same postcode (such as virtual offices, company formation agents, or foreign online sellers), which can distort local survival rates. The [Multiple Business Registrations methodology paper](https://www.ons.gov.uk/businessindustryandtrade/business/activitysizeandlocation/articles/multiplebusinessregistrationsatasinglepostcodeuk/latest) explains this and provides tables identifying postcodes with 500 or more business births or deaths. These registrations cannot be removed from the Business Register, but users may wish to consider their impact when interpreting local figures."

This dataset records the number of enterprises that were live at a reference point in March each year. An enterprise can be thought of as the overall business, made up of all the individual sites or workplaces. It is defined as the smallest combination of legal units (generally based on VAT and/or PAYE records) that has a certain degree of autonomy within an enterprise group. Please refer to the [UK business; activity, size and location quality and methods guide](https://www.ons.gov.uk/businessindustryandtrade/business/activitysizeandlocation/methodologies/ukbusinessactivitysizeandlocationqmi) for more information. Mid-year population estimates for the period 2010 to 2024 have been used to calculate rates per 1,000 population (sourced from [Nomis](https://www.nomisweb.co.uk/datasets/pestsyoala)). The most recent (2024) population estimates have been used to produce rates for the 2025 data."

This dataset records the number of enterprises that were live at a reference point in March each year. An enterprise can be thought of as the overall business, made up of all the individual sites or workplaces. It is defined as the smallest combination of legal units (generally based on VAT and/or PAYE records) that has a certain degree of autonomy within an enterprise group. Please refer to the [UK business; activity, size and location quality and methods guide](https://www.ons.gov.uk/businessindustryandtrade/business/activitysizeandlocation/methodologies/ukbusinessactivitysizeandlocationqmi) for more information. Mid-year population estimates for the period 2010 to 2024 have been used to calculate rates per 1,000 population (sourced from [Nomis](https://www.nomisweb.co.uk/datasets/pestsyoala)). The most recent (2024) population estimates have been used to produce rates for the 2025 data."

        "A business is deemed to have survived for four years if it is active in terms of employment and/or turnover at any point during the fourth calendar year following its year of birth. The four‑year business survival rate is calculated as the number of businesses that survive for four years as a proportion of businesses born in the start year. Some areas are affected by large numbers of businesses registering or de-registering at the same postcode (such as virtual offices, company formation agents, or foreign online sellers), which can distort local survival rates. The [Multiple Business Registrations methodology paper](https://www.ons.gov.uk/businessindustryandtrade/business/activitysizeandlocation/articles/multiplebusinessregistrationsatasinglepostcodeuk/latest) explains this and provides tables identifying postcodes with 500 or more business births or deaths. These registrations cannot be removed from the Business Register, but users may wish to consider their impact when interpreting local figures."

          "A business is deemed to have survived for four years if it is active in terms of employment and/or turnover at any point during the fourth calendar year following its year of birth. The four‑year business survival rate is calculated as the number of businesses that survive for four years as a proportion of businesses born in the start year. Some areas are affected by large numbers of businesses registering or de-registering at the same postcode (such as virtual offices, company formation agents, or foreign online sellers), which can distort local survival rates. The [Multiple Business Registrations methodology paper](https://www.ons.gov.uk/businessindustryandtrade/business/activitysizeandlocation/articles/multiplebusinessregistrationsatasinglepostcodeuk/latest) explains this and provides tables identifying postcodes with 500 or more business births or deaths. These registrations cannot be removed from the Business Register, but users may wish to consider their impact when interpreting local figures."

Local authority and region geographies are derived from the postcode of child residency; only children with valid geographical coding (postcode of residence) have been included in the analysis.

        "England and Wales data has been extracted from the Home Office Homicide Index, which contains detailed record-level information about each homicide recorded by police in England and Wales. This index is continually updated with revised information from the police as investigations continue and as cases are heard by the courts. The data refer to the position as at 5 December 2025 and will change as subsequent court hearings take place or as further information is received. In contrast, the Northern Ireland homicide figures represent those initially recorded as homicide, with no revisions based on further police or court decisions. Northern Ireland statistics on police recorded crime are collated and produced by statisticians seconded to the Police Service of Northern Ireland (PSNI) from the Northern Ireland Statistics and Research Agency (NISRA). They are recorded in compliance with the Home Office Counting Rules and further details of recording practices are available in the [User Guide to Police Recorded Crime Statistics](https://www.psni.police.uk/sites/default/files/2025-11/Police%20Recorded%20Crime%20User%20Guide.pdf). Mid-year population estimates covering the years 2015 to 2023 have been used to create rate per milion population. The mid-year estimate in the middle of the three-year period was used, for example the period 04/2022 to 03/2025 used 2023 mid-year population estimates. Some of this data has been aggregated and may show differences to other published figures."

          "England and Wales data has been extracted from the Home Office Homicide Index, which contains detailed record-level information about each homicide recorded by police in England and Wales. This index is continually updated with revised information from the police as investigations continue and as cases are heard by the courts. The data refer to the position as at 5 December 2025 and will change as subsequent court hearings take place or as further information is received. In contrast, the Northern Ireland homicide figures represent those initially recorded as homicide, with no revisions based on further police or court decisions. Northern Ireland statistics on police recorded crime are collated and produced by statisticians seconded to the Police Service of Northern Ireland (PSNI) from the Northern Ireland Statistics and Research Agency (NISRA). They are recorded in compliance with the Home Office Counting Rules and further details of recording practices are available in the [User Guide to Police Recorded Crime Statistics](https://www.psni.police.uk/sites/default/files/2025-11/Police%20Recorded%20Crime%20User%20Guide.pdf). Mid-year population estimates covering the years 2015 to 2023 have been used to create rate per milion population. The mid-year estimate in the middle of the three-year period was used, for example the period 04/2022 to 03/2025 used 2023 mid-year population estimates. Some of this data has been aggregated and may show differences to other published figures."

Because of increased volatility of LFS and APS estimates, estimates of change should be treated with additional caution. Updates to this indicator have been temporarily suspended until the APS reweighting is implemented in 2026.

        "This indicator previously reported the number of publicly available electric vehicle (EV) charging devices. As of May 2026, it focuses on publicly available EV chargers, representing an improvement from measuring the number of devices which can be charged at to the number of vehicles which can be charged. Reporting chargers provides a more representative estimate of the UK’s public EV charging infrastructure and aligns with wider international practice. Data are provided by individual charge point operators (CPOs) as set out in the [Public Charge Point Regulations 2023 guidance](https://www.gov.uk/government/publications/the-public-charge-point-regulations-2023-guidance/public-charge-point-regulations-2023-guidance) and collated by Zapmap for use by the Department for Transport (DfT). The data represent the number of chargers reported as operational at 00:00 on the first day of each quarter. There are instances where the published number of public EV chargers in a local authority goes down from one statistical publication to the next, or where a local increase is followed shortly by a decrease of a similar magnitude. This can be caused by quality revisions from an individual CPO and does not necessarily represent a real reduction in the availability of public EV charging infrastructure in the area. This can also happen if a CPO installs new chargers to replace old chargers which are decommissioned gradually over time. Population estimates used to calculate the per 100,000 population figures were sourced from the Office for National Statistics Mid-Year Estimates 2024. Some of this data has been aggregated and may show differences to other published figures."

Data are provided by individual charge point operators (CPOs) as set out in the [Public Charge Point Regulations 2023 guidance](https://www.gov.uk/government/publications/the-public-charge-point-regulations-2023-guidance/public-charge-point-regulations-2023-guidance) and collated by Zapmap for use by the Department for Transport (DfT). The data represent the number of chargers reported as operational at 00:00 on the first day of each quarter. There are instances where the published number of public EV chargers in a local authority goes down from one statistical publication to the next, or where a local increase is followed shortly by a decrease of a similar magnitude. This can be caused by quality revisions from an individual CPO and does not necessarily represent a real reduction in the availability of public EV charging infrastructure in the area. This can also happen if a CPO installs new chargers to replace old chargers which are decommissioned gradually over time. Population estimates used to calculate the per 100,000 population figures were sourced from the Office for National Statistics Mid-Year Estimates 2024. Some of this data has been aggregated and may show differences to other published figures."

        "Unemployment rates are calculated as a percentage of aged 16 years and over economically active population. As unemployed form a small percentage of the population, the Annual Population Survey (APS) unemployment estimates within local authorities are based on very small samples so for many areas are unreliable. To overcome this model-based estimates have been developed that provide better estimates of total unemployed for local authorities. The ongoing challenges with response rates, response levels and weighting approach mean that labour market statistics based on both the Labour Force Survey (LFS) and Annual Population Survey (APS) will be considered [official statistics in development](https://osr.statisticsauthority.gov.uk/policies/official-statistics-policies/official-statistics-in-development/) until further review. Because of increased volatility of LFS and APS estimates, estimates of change should be treated with additional caution. Updates to this indicator have been temporarily suspended until the APS reweighting is implemented in 2026. The model-based estimate improves on the APS estimate by borrowing strength from the claimant count to produce an estimate that is more precise i.e. has a smaller confidence interval. The claimant count is not itself a measure of unemployment but is strongly correlated with unemployment, and, as it is an administrative count, is known without sampling error. The gain in precision is greatest for areas with smaller sample sizes. Refer to the [user guide (pdf)](https://www.ons.gov.uk/file?uri=/employmentandlabourmarket/peopleinwork/employmentandemployeetypes/methodologies/subnationallabourmarket/modelbasedestimatesunemploymenttcm77252969.pdf) for further details."

          "Unemployment rates are calculated as a percentage of aged 16 years and over economically active population. As unemployed form a small percentage of the population, the Annual Population Survey (APS) unemployment estimates within local authorities are based on very small samples so for many areas are unreliable. To overcome this model-based estimates have been developed that provide better estimates of total unemployed for local authorities. The ongoing challenges with response rates, response levels and weighting approach mean that labour market statistics based on both the Labour Force Survey (LFS) and Annual Population Survey (APS) will be considered [official statistics in development](https://osr.statisticsauthority.gov.uk/policies/official-statistics-policies/official-statistics-in-development/) until further review. Because of increased volatility of LFS and APS estimates, estimates of change should be treated with additional caution. Updates to this indicator have been temporarily suspended until the APS reweighting is implemented in 2026. The model-based estimate improves on the APS estimate by borrowing strength from the claimant count to produce an estimate that is more precise i.e. has a smaller confidence interval. The claimant count is not itself a measure of unemployment but is strongly correlated with unemployment, and, as it is an administrative count, is known without sampling error. The gain in precision is greatest for areas with smaller sample sizes.

        "A threshold of five years of earnings is used as a broad indicator of affordability. Housing affordability estimates are calculated by dividing house sales prices for an area by average earnings to create a ratio. This ratio allows comparisons between areas and over time without needing to adjust for inflation. A higher housing affordability ratio reflects a less affordable area. Earnings data are from the [Annual Survey of Hours and Earnings (ASHE)](https://www.ons.gov.uk/employmentandlabourmarket/peopleinwork/earningsandworkinghours/datasets/placeofresidencebylocalauthorityashetable8), which provides a snapshot of earnings at April in each year. Earnings relate to gross full-time individual earnings for people who live in the area, though they may work elsewhere. A snapshot of the annual earnings of all full-time employees is used, or an annualised version of the weekly estimate where annual data are not available. House price statistics are from [house prices for small areas](https://www.ons.gov.uk/peoplepopulationandcommunity/housing/bulletins/housingaffordabilityinenglandandwales/2024/relateddata), which report the median price paid for residential property and refer to a 12 month period with April in the middle (year ending September). The House price statistics for small areas (HPSSA) data used here are not mix adjusted, so price variations may be a combination of true price changes and differences in the mix of housing types and trends. They will therefore differ from those in the [Private rent and house prices, UK bulletins](https://www.ons.gov.uk/economy/inflationandpriceindices/bulletins/privaterentandhousepricesuk/previousreleases), which are mix adjusted and comparable over time. These affordability ratio statistics are revised annually to reflect revisions to the house price statistics and earnings data. Please refer to the [Housing affordability in England and Wales bulletin](https://www.ons.gov.uk/peoplepopulationandcommunity/housing/bulletins/housingaffordabilityinenglandandwales/latest) for further information. This bulletin includes analysis of workplace‑based earnings affordability for all dwellings, which is used in England within the updated standard method for [assessing local housing need](https://www.gov.uk/guidance/housing-and-economic-development-needs-assessments)."

          "A threshold of five years of earnings is used as a broad indicator of affordability. Housing affordability estimates are calculated by dividing house sales prices for an area by average earnings to create a ratio. This ratio allows comparisons between areas and over time without needing to adjust for inflation. A higher housing affordability ratio reflects a less affordable area. Earnings data are from the [Annual Survey of Hours and Earnings (ASHE)](https://www.ons.gov.uk/employmentandlabourmarket/peopleinwork/earningsandworkinghours/datasets/placeofresidencebylocalauthorityashetable8), which provides a snapshot of earnings at April in each year. Earnings relate to gross full-time individual earnings for people who live in the area, though they may work elsewhere. A snapshot of the annual earnings of all full-time employees is used, or an annualised version of the weekly estimate where annual data are not available. House price statistics are from [house prices for small areas](https://www.ons.gov.uk/peoplepopulationandcommunity/housing/bulletins/housingaffordabilityinenglandandwales/2024/relateddata), which report the median price paid for residential property and refer to a 12 month period with April in the middle (year ending September). The House price statistics for small areas (HPSSA) data used here are not mix adjusted, so price variations may be a combination of true price changes and differences in the mix of housing types and trends. They will therefore differ from those in the [Private rent and house prices, UK bulletins](https://www.ons.gov.uk/economy/inflationandpriceindices/bulletins/privaterentandhousepricesuk/previousreleases), which are mix adjusted and comparable over time. These affordability ratio statistics are revised annually to reflect revisions to the house price statistics and earnings data. Please refer to the [Housing affordability in England and Wales bulletin](https://www.ons.gov.uk/peoplepopulationandcommunity/housing/bulletins/housingaffordabilityinenglandandwales/latest) for further information. This bulletin includes analysis of workplace‑based earnings affordability for all dwellings, which is used in England within the updated standard method for [assessing local housing need](https://www.gov.uk/guidance/housing-and-economic-development-needs-assessments)."

This 1991 Census Enumeration District (ED) boundary set – developed from the 1990s boundary set produced by the ED-line consortium – resolves long-standing issues with versions available elsewhere. Previously unaddressed problems included small-population EDs that were formed into amalgamated areas which previously could not be mapped correctly, the impacts of boundary-change Statutory Instruments taking effect before the 1991 Census Day, and various inaccuracies around the coast. The ED polygons can be matched to the ED-level SAS data available at NOMIS ( https://www.nomisweb.co.uk/datasets/sas91 ) using the field ‘NOMIS_code’.

      "notes": "This file contains the digital vector boundaries for the GEOSTAT grid in the UK as at 31 December 2011, as produced and supplied by Eurostat. The file was created as part of a ‘Pan-European' grid system. The grid contains 2011 Census data on total population and number of households for the United Kingdom and a break down by sex for England, Wales and Northern Ireland. This data is provided on the basis of the previously released postcode information from the Census where each postcode (and its associated data) is allocated to the GEOSTAT grid on the basis of its grid reference (point-in-polygon). The file is in GRE format (grid, extent), meaning that is grid formed of equally sized cells which extends beyond the coastline. It can be used to aggregate statistics to equally sized 'areas’. Please note that this product contains Eurostat, National Records of Scotland, Northern Ireland Statistics and Research Agency and ONS Intellectual Property Rights. The services for the GEOSTAT Grids are published in the ETRS 1989 LAEA projection. As the file is not in the British National Grid (BNG) projection, it may not line up with other spatial datasets.

      "notes": "A best-fit lookup between Output Areas (OA) to Nomenclature of Territorial Units for Statistics (NUTS) and Local Administrative Units (LAU) as at 31 December 2011 in England and Wales. The NUTS areas (Levels 1, 2 and 3) are operative as at January 2006 and the LAU areas (Levels 1 and 2) are operative as at January 2010. The methodology used to create the OA lookups is based on the distribution of 2011 Census population. A median average of each OA's household grid references, weighted by the population at each household has been used to create a population weighted centroid for each OA. This centroid has been used to allocate the OA and all its associated statistics to any higher geographies. Information on the percentage of an output areas population that falls into the higher geography has also been included in this best-fit lookup file. A ‘best-fit percentage’ indicator has been included in this lookup, to support an understanding of the actual relationship between the OA and the higher geography to which it has been best-fitted. This ‘best-fit percentage' indicator has been calculated by working out the percentage of the OA’s population that falls exactly within the output geography's boundary. This is calculated by plotting the grid references of the households into the output geography's digitised boundaries and aggregating the population that actually falls within the best-fitted geography's boundary. 100 indicates that all the OA's population actually fell within the best-fitted boundary. A value of 90 means that the OA's boundary is split across the output geography's boundary and that 90% of the OA's population actually fell within the geography the OA was best-fitted to. Only the higher geography to which the OA has been allocated will be given a percentage match. (File Size 26.5MB).

      "notes": "A best fit lookup between output areas and National Assembly for Wales constituencies (NAWC) and National Assembly for Wales electoral regions (NAWER) as at 31 December 2011 in Wales. The methodology used to create the OA Lookups is based on the distribution of 2011 Census population. A median average of each OA's household grid references, weighted by the population at each household has been used to create a population weighted centroid for each OA. This centroid has been used to allocate the OA and all its associated statistics to any higher geographies. Information on the percentage of an output areas population that falls into the higher geography has also been included in this best-fit lookup file. A ‘best-fit percentage’ indicator has been included in this lookup, to support an understanding of the actual relationship between the OA and the higher geography to which it has been best-fitted. This ‘best-fit percentage' indicator has been calculated by working out the percentage of the OA’s population that falls exactly within the output geography's boundary. This is calculated by plotting the grid references of the households into the output geography's digitised boundaries and aggregating the population that actually falls within the best-fitted geography's boundary. 100 indicates that all the OA's population actually fell within the best-fitted boundary. A value of 90 means that the OA's boundary is split across the output geography's boundary and that 90% of the OA's population actually fell within the geography the OA was best-fitted to. Only the higher geography to which the OA has been allocated will be given a percentage match (File Size 1MB). >REST URL of Feature Access Service – https://services1.arcgis.com/ESMARspQHYMw9BZ9/arcgis/rest/services/OA11_NAWC11_NAWER11_WA_LU_f2c7d1d156684ff396b95fe2a842a66c/FeatureServer For more information and an overview of best-fitting follow this link - https://geoportal.statistics.gov.uk/datasets/f0aac7ccbfd04cda9eb03",

      "notes": "A best-fit lookup between Output Areas (OA), civil parishes / communities and local authority districts (LAD) as at 31 December 2011 in England and Wales. This lookup has been provided with a 'small population indicator' field. This field indicates those parishes / communities which have a very small population. There are two designated categories to describe the changes, and these are as follows: - 0 - normal population, - 1 - very small population. Where a parish / community is smaller than an OA and therefore does not contain any OA population weighted centroids, the parish / community is allocated to the OA with its population weighted centroid nearest to any part of the parish / community. The methodology used to create the OA lookups is based on the distribution of 2011 Census population. A median average of each OA's household grid references, weighted by the population at each household has been used to create a population weighted centroid for each OA. This centroid has been used to allocate the OA and all its associated statistics to any higher geographies. (File Size 8.6MB).

A median average of each OA's household grid references, weighted by the population at each household has been used to create a population weighted centroid for each OA. This centroid has been used to allocate the OA and all its associated statistics to any higher geographies. Information on the percentage of an OAs population that falls into the higher geography has also been included in this best-fit lookup file. A ‘best-fit percentage’ indicator has been included in this lookup, to support an understanding of the actual relationship between the OA and the higher geography to which it has been best-fitted. This ‘best-fit percentage' indicator has been calculated by working out the percentage of the OA population that falls exactly within the output geography's boundary. This is calculated by plotting the grid references of the households into the output geography's digitised boundaries and aggregating the population that actually falls within the best-fitted geography's boundary. 100 indicates that all the OA population actually fell within the best-fitted boundary. A value of 90 means that the OA boundary is split across the output geography's boundary and that 90% of the OA population actually fell within the geography the OA was best-fitted to. Only the higher geography to which the OA has been allocated will be given a percentage match. (File Size 12.3MB).

      "notes": "A best-fit lookup between Output Areas (OA), Westminster parliamentary constituencies and European electoral regions (EER) as at 31 December 2011 in England and Wales. A ‘best-fit percentage’ indicator has been included in this lookup, to support an understanding of the actual relationship between the OA and the higher geography to which it has been best-fitted. This ‘best-fit percentage' indicator has been calculated by working out the percentage of the OA population that falls exactly within the output geography. This is calculated by plotting the grid references of the households into the output geography and aggregating the population that actually falls within the best-fitted geography. Only the higher geography to which the OA has been allocated will be given a percentage match. The other higher geographies that the OA shares its population with are not included in the best-fit lookup, and so will not be given a ‘best-fit percentage' indicator. The only exception to this will be those higher geographies, designated as having a ‘small population’. These are certain geographies that are smaller than an OA and therefore do not contain an OA population weighted centroid. For completeness of coverage, these geographies are included in the lookup based on a manual allocation of an OA to the geography, and will therefore also be given a percentage match of the OA population to the geography. Due to the nature of the OA design, and administrative area realignment, there are some OA which have low or no population in the higher geography to which they have been allocated. This is the result of the distribution of the population within certain OA, but they should still be allocated to higher geographies based on their population weighted centroid, in line with the Geography Policy for National Statistics and to keep the methodology for the production of best-fitted statistics consistent.

      "notes": "A best-fit lookup between output areas and enumeration postcode sectors as at 31 December 2011 in England and Wales. The 2011 OA to enumeration postcode sector (E&W) lookup has been created from a base file, namely the residential postcode (census enumeration only) to 2011 OA lookup. The base file was created by best-fitting postcodes to 2011 OA by plotting the postcode centroid (the point of the mean address in the postcode) into the 2011 OA. To create a 2011 OA to postcode sector lookup from the base file, the following processes were run: - postcodes were truncated to five characters (postcode sector level) from seven characters (unit postcode level). - these five character postcode sectors were grouped to form a postcode sector to OA lookup (many postcode sectors to many OA). - each unique OA was then assigned to a single postcode sector. If an OA covered more than one postcode sector, the postcode sector with most Census population falling in the OA was assigned. This gives a one OA to many postcode sectors lookup. Postcode sectors can cross administrative areas and will only be aligned within the defined postcode hierarchy. (File Size 3MB).

      "notes": "A best fit lookup between Output Areas (OA), wards and local authority districts (LAD) as at 31 December 2011 in England and Wales. This lookup has been provided with a 'small population indicator' field. This field indicates those wards which have a very small population. There are two designated categories to describe the changes, - 0 - normal population, - 1 - very small population. Where a ward is smaller than an OA and therefore does not contain any OA population weighted centroids, the ward is allocated to the OA with its population weighted centroid nearest to any part of the ward. Information on the percentage of an OA’s population that falls into the higher geography has also been included in this best-fit lookup file. This ‘best-fit percentage' indicator has been calculated by working out the percentage of the OA’s population that falls exactly within the output geography. In the case of the OA to Ward lookup three OAs have a 0% of their population in the ward to which they are allocated. The affected OA are E00071944, E00120017 and E00026547, and all are the result of the wards not aligning with the 2001 OAs. The OAs with less than 100% of their population within their allocated ward are because of the process of 'best-fitting' by which they were allocated. Each OA was assigned to a single ward on the basis of its population weighted centroid. This meant that for statistical purposes, an OA had all of its counts assigned to that ward, even if the reality was that the geographic area may have covered several wards. This is why the 'percentage best-fit match' was created - the percentage of an OAs actual population that fell within its allocated ward rather than the total population of the OA that is used for statistical purposes. This was designed to help statistical users better understand the best-fitting process. (File Size 11.6MB).

Enumeration postcodes are a sub-Output Area (OA) geography used only for the publication of estimates of males, females and households in the 2011 Census. The enumeration postcodes are defined as only those valid unit postcodes that were recorded during the 2011 Census as containing usually resident population. Postcodes have been assigned using a ‘point-in-polygon’ methodology that plots each postcode's mean address (centroid) into the areas of each of the parishes / communities, wards and local authority districts (LAD). In England there is not a full coverage of parishes, so the 2011 Census enumeration postcodes that do not fall into a parish will have no parish allocation. There are also 23 parishes (0.2%) that do not contain any enumeration postcode centroids. This occurs where a parish contains population, but the centroid of the postcode falls outside the parish. In these instances it is not possible to allocate a postcode to the parish.",

      "notes": "The Rural Definition was introduced in 2004 as a joint project between the Commission for Rural Communities (CRC - formerly the Countryside Agency), the Department for Environment, Food and Rural Affairs (Defra), the Office for National Statistics (ONS), the Office of the Deputy Prime Minister (ODPM) and the Welsh Assembly. It was delivered by the Rural Evidence Research Centre at Birkbeck College (RERC). A) This new 'spectrum', or graded system, replaces the earlier Oxford/CA binary ward classification and adopts a settlement-based approach. B) It is available for England and Wales at: Census Output Area (COA or OA) Census Super Output Area (CSOA or SOA) Ward [OAs consist of ~125 households and have a population of ~300. SOAs are built of OAs, typically 5, and so contain ~625 households or a mean population of ~1500. OAs therefore vary greatly in size and shape between urban and rural regions, for example a single tower block may consist of more than one OA, whereas a large area of remote moorland may be covered by a single OA.] More information on OAs and SOAs . C) Output areas are classified by morphology and context: Morphology Urban (over 10,000) Rural town Village Dispersed (hamlets and isolated dwellings) And context Sparse Less sparse This gives 8 Urban/Rural Classification (1 urban and 6 rural): Urban (Sparse) Urban (Less Sparse) Town (Less Sparse) Town (Sparse) Village (Less Sparse) Village (Sparse) Dispersed (Less Sparse) Dispersed (Sparse) In April 2009 significant changes in the structure of local government came into force. These changes, especially the creation of 9 new unitary authorities, have necessitated an update to the Local Authority Classification. The Government Statistical Service Regional and Geography Group (GSSRG) commissioned a working group to look at this issue, and the outcome of this working group is a revised LA Classification. Detailed information about the changes can be found here , with guidance on how to use the Definition and ",

The 2011 rural-urban classification (RUC) of clinical commissioning groups (CCG) in England is based on the 2011 RUC of output areas published in August 2013, and allows users to create a rural/urban view of clinical commissioning group level products. The classification was produced by the University of Sheffield and was sponsored by a cross-Government working group comprising Department for Environment, Food and Rural Affairs, Department of the Communities and Local Government and Office for National Statistics. Also included are a range of population counts for each CCG including - Total Rural population (2011), Urban City and Town population (2011), Urban Minor Conurbation population (2011), Urban Major Conurbation population (2011), Total Urban population (2011), Total population (2011), Hub towns (rural related) population included in Urban population (2011), Rural including hub towns (rural & rural related) population (2011) and Rural including hub towns (rural & rural related) population as % of Total population (2011).",

      "notes": "The 2011 rural-urban classification (RUC) of middle layer super output areas (MSOA) in England and Wales is based on the 2011 RUC of output areas published in August 2013, and allows users to create a rural/urban view of MSOA level products. This product was sponsored by a cross-Government working group comprising Department for Environment, Food and Rural Affairs, Department of the Communities and Local Government, Office for National Statistics and the Welsh Government. The classification at LSOA level is built from the RUC at OA level (the most detailed version of the classification). Assignments of MSOA to urban or rural categories are made by reference to the category to which the majority of their constituent OA are assigned. In the RUC at OA level, output areas are treated as ‘urban’ if they were allocated to a 2011 built-up area with a population of 10,000 or more. The urban domain is then further sub-divided into three broad morphological types based on the predominant settlement component. As with the previous version of the classification, the remaining ‘rural’ output areas are grouped into three broad morphological types based on the predominant settlement component. At the MSOA scale settlement form is less homogenous than at OA level and so there are just two rural settlement types. The classification also categorises output areas based on context – i.e. whether the wider surrounding area of a given output area is sparsely populated or less sparsely populated (File Size 368KB).

The product was sponsored by a cross-Government working group comprising Department for Environment, Food and Rural Affairs, Department for Communities and Local Government, Office for National Statistics and the Welsh Government. OAs are treated as ‘urban’ if they were allocated to a 2011 built-up area with a population of 10,000 or more. The urban domain is then further sub-divided into three broad morphological types based on the predominant settlement component. As with the previous version of the classification, the remaining ‘rural’ OAs are grouped into three broad morphological types based on the predominant settlement component. The classification also categorises OAs based on context – i.e. whether the wider surrounding area of a given OA is sparsely populated or less sparsely populated.",

      "notes": "This file provides a rural-urban view of 2011 electoral wards / divisions. The 2011 rural-urban classification of electoral wards / divisions was released in August 2013. This product was sponsored by a cross-Government working group comprising Department for Environment, Food and Rural Affairs, Department of the Communities and Local Government, Office for National Statistics and the Welsh Government. The classification at electoral wards / divisions level is built from the RUC at OA level (the most detailed version of the classification). Assignments of electoral wards / divisions to urban or rural categories are made by reference to the category to which the majority of their constituent OA are assigned. In the RUC at OA level, output areas are treated as ‘urban’ if they were allocated to a 2011 built-up area with a population of 10,000 or more. The urban domain is then further sub-divided into three broad morphological types based on the predominant settlement component. As with the previous version of the classification, the remaining ‘rural’ output areas are grouped into three broad morphological types based on the predominant settlement component. At the electoral wards / divisions scale settlement form is less homogeneous than at OA level and so there are just two rural settlement types. The classification also categorises output areas based on context – i.e. whether the wider surrounding area of a given output area is sparsely populated or less sparsely populated (File Size 429KB).

This part of the Rural Urban Classification is available only for England and complements another part of the classification concerned to classify small areas (Output Areas (OAs); Super Output Areas (SOAs) and wards) in both England and Wales. It is important to appreciate that to a substantial degree the classification in both its new and earlier forms rests on this corresponding lower level classification. This lower level small-area classification was originally developed for a consortium of government agencies for use with the 2001 Census and revised following the 2011 Census for a similar consortium which included the Department of Communities and Local Government (DCLG), the Department of Environment, Food and Rural Affairs (Defra), the Office for National Statistics (ONS) and the Welsh Government (WG). The RUCLAD classification was produced by the University of Sheffield and was sponsored by a cross-Government working group comprising Department for Environment, Food and Rural Affairs, Department of the Communities and Local Government and Office for National Statistics. 21/06/2017: UPDATED - it was noticed that not all the fields were present on the original - possibly due to a corruption when uploading the CSV file to ArcGIS Online. This has been rectified by uploading the files in ZIP file format.",

      "notes": "This zip file contains the Standard Area Measurements (SAM) for the 2021 Statistical Areas in England and Wales as at Census Day (21 March 2021). This includes the Output Areas (OA), Lower layer Super Output Areas (LSOA), Middle layer Super Output Areas (MSOA), the Lower-Tier Local Authorities (LTLA) including the Unitary Authorities (E06 and W06), Non-metropolitan Districts (E07), Metropolitan Districts (E08) and London Boroughs (E09), the Upper-Tier Local Authorities (UTLA) including the Unitary Authorities (E06 and W06), Counties (E10), Metropolitan Districts (E08) and London Boroughs (E09), the Regions including the country of Wales, Countries and National. All measurements provided are ‘flat’ as they do not take into account variations in relief e.g. mountains and valleys. Measurements are given in hectares (10,000 square metres) to 2 decimal places and square kilometres to 4 decimal places. Four types of measurements are included: total extent (AREAEHECT), area to mean high water (coastline) (AREACHECT), area of inland water (AREAIHECT) and area to mean high water excluding area of inland water (land area) (AREALHECT). The Eurostat-recommended approach is to use the ‘land area’ measurement to compile population density figures. This V2 is because the user guide name was too long. PLEASE NOTE: There is an extremely small OA with the code E00187556 and measures 400 centimetres squared. This is because all the population and household points are centred around a very small space and to make sure it was in threshold it was manually changed to make it within threshold.

This dataset has been generalised to 10 metre resolution where it is still but the space needed for downloads will be improved. A set of UK wide estimated travel area geometries (isochrones), from Output Area (across England, Scotland, and Wales) and Small Area (across Northern Ireland) population-weighted centroids. The modes used in the isochrone calculations are limited to public transport and walking. Generated using Open Trip Planner routing software in combination with Open Street Maps and open public transport schedule data (UK and Ireland). The geometries provide an estimate of reachable areas by public transport and on foot between 7:15am and 9:15am for a range of maximum travel durations (15, 30, 45 and 60 minutes). For England, Scotland and Wales, these estimates were generated using public transport schedule data for Tuesday 15 th November 2022. For Northern Ireland, the date used is Tuesday 6 th December 2022. The data is made available as a set of ESRI shape files, in .zip format. This corresponds to a total of 18 files; one for Northern Ireland, one for Wales, twelve for England (one per English region, where London, South East and North West have been split into two files each) and four for Scotland (one per NUTS2 region, where the ‘North-East’ and ‘Highlands and Islands’ have been combined into one shape file, and South West Scotland has been split into two files). The shape files contain the following attributes. For further details, see the ‘Access Constraints or User Limitations’ section: Attribute Description OA21CD or SA2011 or OA11CD England and Wales: The 2021 Output Area code. Northern Ireland: The 2011 Small Area code. Scotland: The 2011 Output Area code. centre_lat The population-weighted centroid latitude. centre_lon The population-weighted centroid longitude. node_lat The latitude of the nearest Open Street Map “highway” node to the popu",

This dataset has been generalised to 10 metre resolution where it is still but the space needed for downloads will be improved. A set of UK wide estimated travel area geometries (isochrones), from Output Area (across England, Scotland, and Wales) and Small Area (across Northern Ireland) population-weighted centroids. The modes used in the isochrone calculations are limited to public transport and walking. Generated using Open Trip Planner routing software in combination with Open Street Maps and open public transport schedule data (UK and Ireland). The geometries provide an estimate of reachable areas by public transport and on foot between 7:15am and 9:15am for a range of maximum travel durations (15, 30, 45 and 60 minutes). For England, Scotland and Wales, these estimates were generated using public transport schedule data for Tuesday 15 th November 2022. For Northern Ireland, the date used is Tuesday 6 th December 2022. The data is made available as a set of ESRI shape files, in .zip format. This corresponds to a total of 18 files; one for Northern Ireland, one for Wales, twelve for England (one per English region, where London, South East and North West have been split into two files each) and four for Scotland (one per NUTS2 region, where the ‘North-East’ and ‘Highlands and Islands’ have been combined into one shape file, and South West Scotland has been split into two files). The shape files contain the following attributes. For further details, see the ‘Access Constraints or User Limitations’ section: Attribute Description OA21CD or SA2011 or OA11CD England and Wales: The 2021 Output Area code. Northern Ireland: The 2011 Small Area code. Scotland: The 2011 Output Area code. centre_lat The population-weighted centroid latitude. centre_lon The population-weighted centroid longitude. node_lat The latitude of the nearest Open Street Map “highway” node to the popu",

      "notes": "This data is experimental, see the ‘Access Constraints or User Limitations’ section for more details. This dataset has been generalised to 10 metre resolution where it is still but the space needed for downloads will be improved. A set of UK wide estimated travel area geometries (isochrones), from Output Area (across England, Scotland, and Wales) and Small Area (across Northern Ireland) population-weighted centroids. The modes used in the isochrone calculations are limited to public transport and walking. Generated using Open Trip Planner routing software in combination with Open Street Maps and open public transport schedule data (UK and Ireland). The geometries provide an estimate of reachable areas by public transport and on foot between 7:15am and 9:15am for a range of maximum travel durations (15, 30, 45 and 60 minutes). For England, Scotland and Wales, these estimates were generated using public transport schedule data for Tuesday 15 th November 2022. For Northern Ireland, the date used is Tuesday 6 th December 2022. The data is made available as a set of ESRI shape files, in .zip format. This corresponds to a total of 18 files; one for Northern Ireland, one for Wales, twelve for England (one per English region, where London, South East and North West have been split into two files each) and four for Scotland (one per NUTS2 region, where the ‘North-East’ and ‘Highlands and Islands’ have been combined into one shape file, and South West Scotland has been split into two files). The shape files contain the following attributes. For further details, see the ‘Access Constraints or User Limitations’ section: Attribute Description OA21CD or SA2011 or OA11CD England and Wales: The 2021 Output Area code. Northern Ireland: The 2011 Small Area code. Scotland: The 2011 Output Area code. centre_lat The population-weighted centroid latitude. centre_lon The population-weighted centroid longitude. node_lat The latitude of the nearest Open Street Map “highway” node to the popu",

This dataset has been generalised to 10 metre resolution where it is still but the space needed for downloads will be improved. A set of UK wide estimated travel area geometries (isochrones), from Output Area (across England, Scotland, and Wales) and Small Area (across Northern Ireland) population-weighted centroids. The modes used in the isochrone calculations are limited to public transport and walking. Generated using Open Trip Planner routing software in combination with Open Street Maps and open public transport schedule data (UK and Ireland). The geometries provide an estimate of reachable areas by public transport and on foot between 7:15am and 9:15am for a range of maximum travel durations (15, 30, 45 and 60 minutes). For England, Scotland and Wales, these estimates were generated using public transport schedule data for Tuesday 15 th November 2022. For Northern Ireland, the date used is Tuesday 6 th December 2022. The data is made available as a set of ESRI shape files, in .zip format. This corresponds to a total of 18 files; one for Northern Ireland, one for Wales, twelve for England (one per English region, where London, South East and North West have been split into two files each) and four for Scotland (one per NUTS2 region, where the ‘North-East’ and ‘Highlands and Islands’ have been combined into one shape file, and South West Scotland has been split into two files). The shape files contain the following attributes. For further details, see the ‘Access Constraints or User Limitations’ section: Attribute Description OA21CD or SA2011 or OA11CD England and Wales: The 2021 Output Area code. Northern Ireland: The 2011 Small Area code. Scotland: The 2011 Output Area code. centre_lat The population-weighted centroid latitude. centre_lon The population-weighted centroid longitude. node_lat The latitude of the nearest Open Street Map “highway” node to the popu",

This dataset has been generalised to 10 metre resolution where it is still but the space needed for downloads will be improved. A set of UK wide estimated travel area geometries (isochrones), from Output Area (across England, Scotland, and Wales) and Small Area (across Northern Ireland) population-weighted centroids. The modes used in the isochrone calculations are limited to public transport and walking. Generated using Open Trip Planner routing software in combination with Open Street Maps and open public transport schedule data (UK and Ireland). The geometries provide an estimate of reachable areas by public transport and on foot between 7:15am and 9:15am for a range of maximum travel durations (15, 30, 45 and 60 minutes). For England, Scotland and Wales, these estimates were generated using public transport schedule data for Tuesday 15 th November 2022. For Northern Ireland, the date used is Tuesday 6 th December 2022. The data is made available as a set of ESRI shape files, in .zip format. This corresponds to a total of 18 files; one for Northern Ireland, one for Wales, twelve for England (one per English region, where London, South East and North West have been split into two files each) and four for Scotland (one per NUTS2 region, where the ‘North-East’ and ‘Highlands and Islands’ have been combined into one shape file, and South West Scotland has been split into two files). The shape files contain the following attributes. For further details, see the ‘Access Constraints or User Limitations’ section: Attribute Description OA21CD or SA2011 or OA11CD England and Wales: The 2021 Output Area code. Northern Ireland: The 2011 Small Area code. Scotland: The 2011 Output Area code. centre_lat The population-weighted centroid latitude. centre_lon The population-weighted centroid longitude. node_lat The latitude of the nearest Open Street Map “highway” node to the popu",

This dataset has been generalised to 10 metre resolution where it is still but the space needed for downloads will be improved. A set of UK wide estimated travel area geometries (isochrones), from Output Area (across England, Scotland, and Wales) and Small Area (across Northern Ireland) population-weighted centroids. The modes used in the isochrone calculations are limited to public transport and walking. Generated using Open Trip Planner routing software in combination with Open Street Maps and open public transport schedule data (UK and Ireland). The geometries provide an estimate of reachable areas by public transport and on foot between 7:15am and 9:15am for a range of maximum travel durations (15, 30, 45 and 60 minutes). For England, Scotland and Wales, these estimates were generated using public transport schedule data for Tuesday 15 th November 2022. For Northern Ireland, the date used is Tuesday 6 th December 2022. The data is made available as a set of ESRI shape files, in .zip format. This corresponds to a total of 18 files; one for Northern Ireland, one for Wales, twelve for England (one per English region, where London, South East and North West have been split into two files each) and four for Scotland (one per NUTS2 region, where the ‘North-East’ and ‘Highlands and Islands’ have been combined into one shape file, and South West Scotland has been split into two files). The shape files contain the following attributes. For further details, see the ‘Access Constraints or User Limitations’ section: Attribute Description OA21CD or SA2011 or OA11CD England and Wales: The 2021 Output Area code. Northern Ireland: The 2011 Small Area code. Scotland: The 2011 Output Area code. centre_lat The population-weighted centroid latitude. centre_lon The population-weighted centroid longitude. node_lat The latitude of the nearest Open Street Map “highway” node to the popu",

      "notes": "This data is experimental, see the ‘Access Constraints or User Limitations’ section for more details. This dataset has been generalised to 10 metre resolution where it is still but the space needed for downloads will be improved. A set of UK wide estimated travel area geometries (isochrones), from Output Area (across England, Scotland, and Wales) and Small Area (across Northern Ireland) population-weighted centroids. The modes used in the isochrone calculations are limited to public transport and walking. Generated using Open Trip Planner routing software in combination with Open Street Maps and open public transport schedule data (UK and Ireland). The geometries provide an estimate of reachable areas by public transport and on foot between 7:15am and 9:15am for a range of maximum travel durations (15, 30, 45 and 60 minutes). For England, Scotland and Wales, these estimates were generated using public transport schedule data for Tuesday 15 th November 2022. For Northern Ireland, the date used is Tuesday 6 th December 2022. The data is made available as a set of ESRI shape files, in .zip format. This corresponds to a total of 18 files; one for Northern Ireland, one for Wales, twelve for England (one per English region, where London, South East and North West have been split into two files each) and four for Scotland (one per NUTS2 region, where the ‘North-East’ and ‘Highlands and Islands’ have been combined into one shape file, and South West Scotland has been split into two files). The shape files contain the following attributes. For further details, see the ‘Access Constraints or User Limitations’ section: Attribute Description OA21CD or SA2011 or OA11CD England and Wales: The 2021 Output Area code. Northern Ireland: The 2011 Small Area code. Scotland: The 2011 Output Area code. centre_lat The population-weighted centroid latitude. centre_lon The population-weighted centroid longitude. node_lat The latitude of the nearest Open Street Map “highway” node to the popu",

This dataset has been generalised to 10 metre resolution where it is still but the space needed for downloads will be improved. A set of UK wide estimated travel area geometries (isochrones), from Output Area (across England, Scotland, and Wales) and Small Area (across Northern Ireland) population-weighted centroids. The modes used in the isochrone calculations are limited to public transport and walking. Generated using Open Trip Planner routing software in combination with Open Street Maps and open public transport schedule data (UK and Ireland). The geometries provide an estimate of reachable areas by public transport and on foot between 7:15am and 9:15am for a range of maximum travel durations (15, 30, 45 and 60 minutes). For England, Scotland and Wales, these estimates were generated using public transport schedule data for Tuesday 15 th November 2022. For Northern Ireland, the date used is Tuesday 6 th December 2022. The data is made available as a set of ESRI shape files, in .zip format. This corresponds to a total of 18 files; one for Northern Ireland, one for Wales, twelve for England (one per English region, where London, South East and North West have been split into two files each) and four for Scotland (one per NUTS2 region, where the ‘North-East’ and ‘Highlands and Islands’ have been combined into one shape file, and South West Scotland has been split into two files). The shape files contain the following attributes. For further details, see the ‘Access Constraints or User Limitations’ section: Attribute Description OA21CD or SA2011 or OA11CD England and Wales: The 2021 Output Area code. Northern Ireland: The 2011 Small Area code. Scotland: The 2011 Output Area code. centre_lat The population-weighted centroid latitude. centre_lon The population-weighted centroid longitude. node_lat The latitude of the nearest Open Street Map “highway” node to the popu",

This dataset has been generalised to 10 metre resolution where it is still but the space needed for downloads will be improved. A set of UK wide estimated travel area geometries (isochrones), from Output Area (across England, Scotland, and Wales) and Small Area (across Northern Ireland) population-weighted centroids. The modes used in the isochrone calculations are limited to public transport and walking. Generated using Open Trip Planner routing software in combination with Open Street Maps and open public transport schedule data (UK and Ireland). The geometries provide an estimate of reachable areas by public transport and on foot between 7:15am and 9:15am for a range of maximum travel durations (15, 30, 45 and 60 minutes). For England, Scotland and Wales, these estimates were generated using public transport schedule data for Tuesday 15 th November 2022. For Northern Ireland, the date used is Tuesday 6 th December 2022. The data is made available as a set of ESRI shape files, in .zip format. This corresponds to a total of 18 files; one for Northern Ireland, one for Wales, twelve for England (one per English region, where London, South East and North West have been split into two files each) and four for Scotland (one per NUTS2 region, where the ‘North-East’ and ‘Highlands and Islands’ have been combined into one shape file, and South West Scotland has been split into two files). The shape files contain the following attributes. For further details, see the ‘Access Constraints or User Limitations’ section: Attribute Description OA21CD or SA2011 or OA11CD England and Wales: The 2021 Output Area code. Northern Ireland: The 2011 Small Area code. Scotland: The 2011 Output Area code. centre_lat The population-weighted centroid latitude. centre_lon The population-weighted centroid longitude. node_lat The latitude of the nearest Open Street Map “highway” node to the popu",

This dataset has been generalised to 10 metre resolution where it is still but the space needed for downloads will be improved. A set of UK wide estimated travel area geometries (isochrones), from Output Area (across England, Scotland, and Wales) and Small Area (across Northern Ireland) population-weighted centroids. The modes used in the isochrone calculations are limited to public transport and walking. Generated using Open Trip Planner routing software in combination with Open Street Maps and open public transport schedule data (UK and Ireland). The geometries provide an estimate of reachable areas by public transport and on foot between 7:15am and 9:15am for a range of maximum travel durations (15, 30, 45 and 60 minutes). For England, Scotland and Wales, these estimates were generated using public transport schedule data for Tuesday 15 th November 2022. For Northern Ireland, the date used is Tuesday 6 th December 2022. The data is made available as a set of ESRI shape files, in .zip format. This corresponds to a total of 18 files; one for Northern Ireland, one for Wales, twelve for England (one per English region, where London, South East and North West have been split into two files each) and four for Scotland (one per NUTS2 region, where the ‘North-East’ and ‘Highlands and Islands’ have been combined into one shape file, and South West Scotland has been split into two files). The shape files contain the following attributes. For further details, see the ‘Access Constraints or User Limitations’ section: Attribute Description OA21CD or SA2011 or OA11CD England and Wales: The 2021 Output Area code. Northern Ireland: The 2011 Small Area code. Scotland: The 2011 Output Area code. centre_lat The population-weighted centroid latitude. centre_lon The population-weighted centroid longitude. node_lat The latitude of the nearest Open Street Map “highway” node to the popu",

This dataset has been generalised to 10 metre resolution where it is still but the space needed for downloads will be improved. A set of UK wide estimated travel area geometries (isochrones), from Output Area (across England, Scotland, and Wales) and Small Area (across Northern Ireland) population-weighted centroids. The modes used in the isochrone calculations are limited to public transport and walking. Generated using Open Trip Planner routing software in combination with Open Street Maps and open public transport schedule data (UK and Ireland). The geometries provide an estimate of reachable areas by public transport and on foot between 7:15am and 9:15am for a range of maximum travel durations (15, 30, 45 and 60 minutes). For England, Scotland and Wales, these estimates were generated using public transport schedule data for Tuesday 15 th November 2022. For Northern Ireland, the date used is Tuesday 6 th December 2022. The data is made available as a set of ESRI shape files, in .zip format. This corresponds to a total of 17 files; one for Northern Ireland, one for Wales, eleven for England (one per English region, where London, and North West have been split into two files each) and four for Scotland (one per NUTS2 region, where the ‘North-East’ and ‘Highlands and Islands’ have been combined into one shape file, and South West Scotland has been split into two files). The shape files contain the following attributes. For further details, see the ‘Access Constraints or User Limitations’ section: Attribute Description OA21CD or SA2011 or OA11CD England and Wales: The 2021 Output Area code. Northern Ireland: The 2011 Small Area code. Scotland: The 2011 Output Area code. centre_lat The population-weighted centroid latitude. centre_lon The population-weighted centroid longitude. node_lat The latitude of the nearest Open Street Map “highway” node to the population-weig",

This dataset has been generalised to 10 metre resolution where it is still but the space needed for downloads will be improved. A set of UK wide estimated travel area geometries (isochrones), from Output Area (across England, Scotland, and Wales) and Small Area (across Northern Ireland) population-weighted centroids. The modes used in the isochrone calculations are limited to public transport and walking. Generated using Open Trip Planner routing software in combination with Open Street Maps and open public transport schedule data (UK and Ireland). The geometries provide an estimate of reachable areas by public transport and on foot between 7:15am and 9:15am for a range of maximum travel durations (15, 30, 45 and 60 minutes). For England, Scotland and Wales, these estimates were generated using public transport schedule data for Tuesday 15 th November 2022. For Northern Ireland, the date used is Tuesday 6 th December 2022. The data is made available as a set of ESRI shape files, in .zip format. This corresponds to a total of 18 files; one for Northern Ireland, one for Wales, twelve for England (one per English region, where London, South East and North West have been split into two files each) and four for Scotland (one per NUTS2 region, where the ‘North-East’ and ‘Highlands and Islands’ have been combined into one shape file, and South West Scotland has been split into two files). The shape files contain the following attributes. For further details, see the ‘Access Constraints or User Limitations’ section: Attribute Description OA21CD or SA2011 or OA11CD England and Wales: The 2021 Output Area code. Northern Ireland: The 2011 Small Area code. Scotland: The 2011 Output Area code. centre_lat The population-weighted centroid latitude. centre_lon The population-weighted centroid longitude. node_lat The latitude of the nearest Open Street Map “highway” node to the popu",

This dataset has been generalised to 10 metre resolution where it is still but the space needed for downloads will be improved. A set of UK wide estimated travel area geometries (isochrones), from Output Area (across England, Scotland, and Wales) and Small Area (across Northern Ireland) population-weighted centroids. The modes used in the isochrone calculations are limited to public transport and walking. Generated using Open Trip Planner routing software in combination with Open Street Maps and open public transport schedule data (UK and Ireland). The geometries provide an estimate of reachable areas by public transport and on foot between 7:15am and 9:15am for a range of maximum travel durations (15, 30, 45 and 60 minutes). For England, Scotland and Wales, these estimates were generated using public transport schedule data for Tuesday 15 th November 2022. For Northern Ireland, the date used is Tuesday 6 th December 2022. The data is made available as a set of ESRI shape files, in .zip format. This corresponds to a total of 18 files; one for Northern Ireland, one for Wales, twelve for England (one per English region, where London, South East and North West have been split into two files each) and four for Scotland (one per NUTS2 region, where the ‘North-East’ and ‘Highlands and Islands’ have been combined into one shape file, and South West Scotland has been split into two files). The shape files contain the following attributes. For further details, see the ‘Access Constraints or User Limitations’ section: Attribute Description OA21CD or SA2011 or OA11CD England and Wales: The 2021 Output Area code. Northern Ireland: The 2011 Small Area code. Scotland: The 2011 Output Area code. centre_lat The population-weighted centroid latitude. centre_lon The population-weighted centroid longitude. node_lat The latitude of the nearest Open Street Map “highway” node to the popu",

This dataset has been generalised to 10 metre resolution where it is still but the space needed for downloads will be improved. A set of UK wide estimated travel area geometries (isochrones), from Output Area (across England, Scotland, and Wales) and Small Area (across Northern Ireland) population-weighted centroids. The modes used in the isochrone calculations are limited to public transport and walking. Generated using Open Trip Planner routing software in combination with Open Street Maps and open public transport schedule data (UK and Ireland). The geometries provide an estimate of reachable areas by public transport and on foot between 7:15am and 9:15am for a range of maximum travel durations (15, 30, 45 and 60 minutes). For England, Scotland and Wales, these estimates were generated using public transport schedule data for Tuesday 15 th November 2022. For Northern Ireland, the date used is Tuesday 6 th December 2022. The data is made available as a set of ESRI shape files, in .zip format. This corresponds to a total of 18 files; one for Northern Ireland, one for Wales, twelve for England (one per English region, where London, South East and North West have been split into two files each) and four for Scotland (one per NUTS2 region, where the ‘North-East’ and ‘Highlands and Islands’ have been combined into one shape file, and South West Scotland has been split into two files). The shape files contain the following attributes. For further details, see the ‘Access Constraints or User Limitations’ section: Attribute Description OA21CD or SA2011 or OA11CD England and Wales: The 2021 Output Area code. Northern Ireland: The 2011 Small Area code. Scotland: The 2011 Output Area code. centre_lat The population-weighted centroid latitude. centre_lon The population-weighted centroid longitude. node_lat The latitude of the nearest Open Street Map “highway” node to the popu",

This dataset has been generalised to 10 metre resolution where it is still but the space needed for downloads will be improved. A set of UK wide estimated travel area geometries (isochrones), from Output Area (across England, Scotland, and Wales) and Small Area (across Northern Ireland) population-weighted centroids. The modes used in the isochrone calculations are limited to public transport and walking. Generated using Open Trip Planner routing software in combination with Open Street Maps and open public transport schedule data (UK and Ireland). The geometries provide an estimate of reachable areas by public transport and on foot between 7:15am and 9:15am for a range of maximum travel durations (15, 30, 45 and 60 minutes). For England, Scotland and Wales, these estimates were generated using public transport schedule data for Tuesday 15 th November 2022. For Northern Ireland, the date used is Tuesday 6 th December 2022. The data is made available as a set of ESRI shape files, in .zip format. This corresponds to a total of 18 files; one for Northern Ireland, one for Wales, twelve for England (one per English region, where London, South East and North West have been split into two files each) and four for Scotland (one per NUTS2 region, where the ‘North-East’ and ‘Highlands and Islands’ have been combined into one shape file, and South West Scotland has been split into two files). The shape files contain the following attributes. For further details, see the ‘Access Constraints or User Limitations’ section: Attribute Description OA21CD or SA2011 or OA11CD England and Wales: The 2021 Output Area code. Northern Ireland: The 2011 Small Area code. Scotland: The 2011 Output Area code. centre_lat The population-weighted centroid latitude. centre_lon The population-weighted centroid longitude. node_lat The latitude of the nearest Open Street Map “highway” node to the popu",

      "notes": "This data is experimental, see the ‘Access Constraints or User Limitations’ section for more details. This dataset has been generalised to 10 metre resolution where it is still but the space needed for downloads will be improved. A set of UK wide estimated travel area geometries (isochrones), from Output Area (across England, Scotland, and Wales) and Small Area (across Northern Ireland) population-weighted centroids. The modes used in the isochrone calculations are limited to public transport and walking. Generated using Open Trip Planner routing software in combination with Open Street Maps and open public transport schedule data (UK and Ireland). The geometries provide an estimate of reachable areas by public transport and on foot between 7:15am and 9:15am for a range of maximum travel durations (15, 30, 45 and 60 minutes). For England, Scotland and Wales, these estimates were generated using public transport schedule data for Tuesday 15 th November 2022. For Northern Ireland, the date used is Tuesday 6 th December 2022. The data is made available as a set of ESRI shape files, in .zip format. This corresponds to a total of 18 files; one for Northern Ireland, one for Wales, twelve for England (one per English region, where London, South East and North West have been split into two files each) and four for Scotland (one per NUTS2 region, where the ‘North-East’ and ‘Highlands and Islands’ have been combined into one shape file, and South West Scotland has been split into two files). The shape files contain the following attributes. For further details, see the ‘Access Constraints or User Limitations’ section: Attribute Description OA21CD or SA2011 or OA11CD England and Wales: The 2021 Output Area code. Northern Ireland: The 2011 Small Area code. Scotland: The 2011 Output Area code. centre_lat The population-weighted centroid latitude. centre_lon The population-weighted centroid longitude. node_lat The latitude of the nearest Open Street Map “highway” node to the popu",

This dataset has been generalised to 10 metre resolution where it is still but the space needed for downloads will be improved. A set of UK wide estimated travel area geometries (isochrones), from Output Area (across England, Scotland, and Wales) and Small Area (across Northern Ireland) population-weighted centroids. The modes used in the isochrone calculations are limited to public transport and walking. Generated using Open Trip Planner routing software in combination with Open Street Maps and open public transport schedule data (UK and Ireland). The geometries provide an estimate of reachable areas by public transport and on foot between 7:15am and 9:15am for a range of maximum travel durations (15, 30, 45 and 60 minutes). For England, Scotland and Wales, these estimates were generated using public transport schedule data for Tuesday 15 th November 2022. For Northern Ireland, the date used is Tuesday 6 th December 2022. The data is made available as a set of ESRI shape files, in .zip format. This corresponds to a total of 18 files; one for Northern Ireland, one for Wales, twelve for England (one per English region, where London, South East and North West have been split into two files each) and four for Scotland (one per NUTS2 region, where the ‘North-East’ and ‘Highlands and Islands’ have been combined into one shape file, and South West Scotland has been split into two files). The shape files contain the following attributes. For further details, see the ‘Access Constraints or User Limitations’ section: Attribute Description OA21CD or SA2011 or OA11CD England and Wales: The 2021 Output Area code. Northern Ireland: The 2011 Small Area code. Scotland: The 2011 Output Area code. centre_lat The population-weighted centroid latitude. centre_lon The population-weighted centroid longitude. node_lat The latitude of the nearest Open Street Map “highway” node to the popu",

We are committed to ITLs aligning with international standards, enabling comparability both over time and internationally, and we will actively monitor global standards to ensure we are following and contributing to the development of world-class statistics. To ensure continued alignment between UK official statistics and international standards, the ITLs will be established as a mirror to the pre-existing NUTS system and will follow a similar timetable to the review of the NUTS system, meaning ITLs will be reviewed every 3 years. New official GSS codes will be developed for the ITL geography aligned with existing NUTS codes. Statistical users are encouraged to adopt the ITL geography from 1 January 2021 as a replacement to NUTS. Lookups between NUTS and ITL geographies will be maintained and published until 2023.",

We are committed to ITLs aligning with international standards, enabling comparability both over time and internationally, and we will actively monitor global standards to ensure we are following and contributing to the development of world-class statistics. To ensure continued alignment between UK official statistics and international standards, the ITLs will be established as a mirror to the pre-existing NUTS system and will follow a similar timetable to the review of the NUTS system, meaning ITLs will be reviewed every 3 years. New official GSS codes will be developed for the ITL geography aligned with existing NUTS codes. Statistical users are encouraged to adopt the ITL geography from 1 January 2021 as a replacement to NUTS. Lookups between NUTS and ITL geographies will be maintained and published until 2023.",

We are committed to ITLs aligning with international standards, enabling comparability both over time and internationally, and we will actively monitor global standards to ensure we are following and contributing to the development of world-class statistics. To ensure continued alignment between UK official statistics and international standards, the ITLs will be established as a mirror to the pre-existing NUTS system and will follow a similar timetable to the review of the NUTS system, meaning ITLs will be reviewed every 3 years. New official GSS codes will be developed for the ITL geography aligned with existing NUTS codes. Statistical users are encouraged to adopt the ITL geography from 1 January 2021 as a replacement to NUTS.",

We are committed to ITLs aligning with international standards, enabling comparability both over time and internationally, and we will actively monitor global standards to ensure we are following and contributing to the development of world-class statistics. To ensure continued alignment between UK official statistics and international standards, the ITLs will be established as a mirror to the pre-existing NUTS system and will follow a similar timetable to the review of the NUTS system, meaning ITLs will be reviewed every 3 years. New official GSS codes will be developed for the ITL geography aligned with existing NUTS codes. Statistical users are encouraged to adopt the ITL geography from 1 January 2021 as a replacement to NUTS.",

This includes: The two new combined authorities - Cambridgeshire and Peterborough and West of England. The names of the combined authorities in this product reflect those that are in common use, both within the areas and beyond. It should be noted that the names are not always the same as the names in the Statutory Instruments that established them. This is because the statutory names are often very long and not suitable for the presentation of statistics.

      "notes": "This zip file contains the Code History Database for the United Kingdom as at April 2018. To download the zip file click the Download button. The Code History Database (CHD) contains the GSS nine-character codes, where allocated, for current and new statistical geographies from 1 January 2009. The codes consist of a simple alphanumeric structure; the first three characters (ANN) represent the area entity (i.e. type; or category of geography) and the following six characters (NNNNNN) represent the specific area instance. The CHD provides multiple functionality including details of codes, relationships, hierarchies and archived data. The CHD can be used in conjunction with the Register of Geographic Codes (RGC) that summarises the range of area instances within each geographic entity. The GSS Coding and Naming policy for some statistical geographies was implemented on 1 January 2011. From this date, where new codes have been allocated they should be used in all exchanges of statistics and published outputs that normally include codes. For further information on this product, please read the user guide and version notes contained within the product zip file. Updated Geographies Updates to Parishes (E04) (name change), Wards (E05) (name change), NMD (E07) (name change), Clinical Commissioning Groups in England (E38), NHS (Region, Local Office) (E39) and NHS England Regions (E40) Updates to Council Areas (S13) and Wards (S13) Updates to the Change History, SI Details, Name Changes, Equivalents table and Information table.

      "notes": "This zip file contains the Code History Database for the United Kingdom as at August 2018. To download the zip file click the Download button. The Code History Database (CHD) contains the GSS nine-character codes, where allocated, for current and new statistical geographies from 1 January 2009. The codes consist of a simple alphanumeric structure; the first three characters (ANN) represent the area entity (i.e. type; or category of geography) and the following six characters (NNNNNN) represent the specific area instance. The CHD provides multiple functionality including details of codes, relationships, hierarchies and archived data. The CHD can be used in conjunction with the Register of Geographic Codes (RGC) that summarises the range of area instances within each geographic entity. The GSS Coding and Naming policy for some statistical geographies was implemented on 1 January 2011. From this date, where new codes have been allocated they should be used in all exchanges of statistics and published outputs that normally include codes. For further information on this product, please read the user guide and version notes contained within the product zip file.

      "notes": "This zip file contains the Code History Database for the United Kingdom as at December 2017. To download the zip file click the Download button. The Code History Database (CHD) contains the GSS nine-character codes, where allocated, for current and new statistical geographies from 1 January 2009. The codes consist of a simple alphanumeric structure; the first three characters (ANN) represent the area entity (i.e. type; or category of geography) and the following six characters (NNNNNN) represent the specific area instance. The CHD provides multiple functionality including details of codes, relationships, hierarchies and archived data. The CHD can be used in conjunction with the Register of Geographic Codes (RGC) that summarises the range of area instances within each geographic entity. The GSS Coding and Naming policy for some statistical geographies was implemented on 1 January 2011. From this date, where new codes have been allocated they should be used in all exchanges of statistics and published outputs that normally include codes. For further information on this product, please read the user guide and version notes contained within the product zip file. Updated Geographies · New entity for County Electoral Divisions (E58) · Updates to Electoral Wards in England (E05), Clinical Commissioning Groups in England (E38) (name changes) and Waste Authorities in England (E50). · Updates to all Geography Constitutions to as at 31/12/2017 · Changes to the SI Details, Name Changes and Information table.

      "notes": "This zip file contains the Code History Database for the United Kingdom as at December 2018. To download the zip file click the Download button. The Code History Database (CHD) contains the GSS nine-character codes, where allocated, for current and new statistical geographies from 1 January 2009. The codes consist of a simple alphanumeric structure; the first three characters (ANN) represent the area entity (i.e. type; or category of geography) and the following six characters (NNNNNN) represent the specific area instance. The CHD provides multiple functionality including details of codes, relationships, hierarchies and archived data. The CHD can be used in conjunction with the Register of Geographic Codes (RGC) that summarises the range of area instances within each geographic entity. The GSS Coding and Naming policy for some statistical geographies was implemented on 1 January 2011. From this date, where new codes have been allocated they should be used in all exchanges of statistics and published outputs that normally include codes. For further information on this product, please read the user guide and version notes contained within the product zip file.

      "notes": "This zip file contains the Code History Database for the United Kingdom as at June 2017. To download the zip file click the Download button. The Code History Database (CHD) contains the GSS nine-character codes, where allocated, for current and new statistical geographies from 1 January 2009. The codes consist of a simple alphanumeric structure; the first three characters (ANN) represent the area entity (i.e. type; or category of geography) and the following six characters (NNNNNN) represent the specific area instance. The CHD provides multiple functionality including details of codes, relationships, hierarchies and archived data. The CHD can be used in conjunction with the Register of Geographic Codes (RGC) that summarises the range of area instances within each geographic entity. The GSS Coding and Naming policy for some statistical geographies was implemented on 1 January 2011. From this date, where new codes have been allocated they should be used in all exchanges of statistics and published outputs that normally include codes. For further information on this product, please read the user guide and version notes contained within the product zip file. Update 3rd July 2017 · Updated a missing record in the changes table. Specifically, there was now record for the change for the South East Midlands LEP from E37000031 to E37000041.

      "notes": "This zip file contains the Code History Database for the United Kingdom as at June 2019. To download the zip file click the Download button. BUG FIX (29th July 2019) A bug was identified in one of the queries that was used to create the equivalents listings within the database. This has now been fixed and the Code History Database is running correctly as of 29th July 2019. Updates to Changes.csv and Equivalents.csv have been made and re-issued within the downloadable ZIP file as a result of this bug fix. The Code History Database (CHD) contains the GSS nine-character codes, where allocated, for current and new statistical geographies from 1 January 2009. The codes consist of a simple alphanumeric structure; the first three characters (ANN) represent the area entity (i.e. type; or category of geography) and the following six characters (NNNNNN) represent the specific area instance. The CHD provides multiple functionality including details of codes, relationships, hierarchies and archived data. The CHD can be used in conjunction with the Register of Geographic Codes (RGC) that summarises the range of area instances within each geographic entity. The GSS Coding and Naming policy for some statistical geographies was implemented on 1 January 2011. From this date, where new codes have been allocated they should be used in all exchanges of statistics and published outputs that normally include codes. For further information on this product, please read the user guide and version notes contained within the product zip file.

      "notes": "This zip file contains the Code History Database for the United Kingdom as at September 2017. To download the zip file click the Download button. The Code History Database (CHD) contains the GSS nine-character codes, where allocated, for current and new statistical geographies from 1 January 2009. The codes consist of a simple alphanumeric structure; the first three characters (ANN) represent the area entity (i.e. type; or category of geography) and the following six characters (NNNNNN) represent the specific area instance. The CHD provides multiple functionality including details of codes, relationships, hierarchies and archived data. The CHD can be used in conjunction with the Register of Geographic Codes (RGC) that summarises the range of area instances within each geographic entity. The GSS Coding and Naming policy for some statistical geographies was implemented on 1 January 2011. From this date, where new codes have been allocated they should be used in all exchanges of statistics and published outputs that normally include codes. For further information on this product, please read the user guide and version notes contained within the product zip file.

The boundaries available are: (BFC) Full resolution - clipped to the coastline (Mean High Water mark). These boundaries ha ve released alongside our 1961 Census Small Area Statistics which are being treated as a beta product in order that we can obtain feedback from users on all aspects of the data, including the boundary work, as this is the first historic Census digitisation product that we’ve released. Contains both Ordnance Survey and ONS Intellectual Property Rights. These boundaries were created by Justin Hayes' team at Salford University.

The NSPL relates both current and terminated postcodes to a range of current statutory geographies via ‘best-fit’ allocation from the 2011 Census Output Areas (national parks and Workplace Zones are exempt from ‘best-fit’ and use ‘exact-fit’ allocations). It supports the production of area based statistics from postcoded data. The NSPL is produced by ONS Geography, who provide geographic support to the Office for National Statistics (ONS) and geographic services used by other organisations. The NSPL is issued quarterly .

To download the zip file click the Download button. The NSPL relates both current and terminated postcodes to a range of current statutory geographies via ‘best-fit’ allocation from the 2011 Census Output Areas (national parks and Workplace Zones are exempt from ‘best-fit’ and use ‘exact-fit’ allocations). It supports the production of area based statistics from postcoded data. The NSPL is produced by ONS Geography, who provide geographic support to the Office for National Statistics (ONS) and geographic services used by other organisations. The NSPL is issued quarterly.

The NSPL relates both current and terminated postcodes to a range of current statutory geographies via ‘best-fit’ allocation from the 2011 Census Output Areas (national parks and Workplace Zones are exempt from ‘best-fit’ and use ‘exact-fit’ allocations). It supports the production of area based statistics from postcoded data. The NSPL is produced by ONS Geography, who provide geographic support to the Office for National Statistics (ONS) and geographic services used by other organisations. The NSPL is issued quarterly .

To download the zip file click the Download button. The NSPL relates both current and terminated postcodes to a range of current statutory geographies via ‘best-fit’ allocation from the 2011 Census Output Areas (national parks and Workplace Zones are exempt from ‘best-fit’ and use ‘exact-fit’ allocations). It supports the production of area based statistics from postcoded data. The NSPL is produced by ONS Geography, who provide geographic support to the Office for National Statistics (ONS) and geographic services used by other organisations. The NSPL is issued quarterly . (File size - 193 MB) . Please note that this product contains Royal Mail, Gridlink, LPS (Northern Ireland), Ordnance Survey and ONS Intellectual Property Rights.",

To download the zip file click the Download button. The NSPL relates both current and terminated postcodes to a range of current statutory geographies via ‘best-fit’ allocation from the 2011 Census Output Areas (national parks and Workplace Zones are exempt from ‘best-fit’ and use ‘exact-fit’ allocations). It supports the production of area based statistics from postcoded data. The NSPL is produced by ONS Geography, who provide geographic support to the Office for National Statistics (ONS) and geographic services used by other organisations. The NSPL is issued quarterly .

To download the zip file click the Download button. The NSPL relates both current and terminated postcodes to a range of current statutory geographies via ‘best-fit’ allocation from the 2011 Census Output Areas (national parks and Workplace Zones are exempt from ‘best-fit’ and use ‘exact-fit’ allocations). It supports the production of area based statistics from postcoded data. The NSPL is produced by ONS Geography, who provide geographic support to the Office for National Statistics (ONS) and geographic services used by other organisations. The NSPL is issued quarterly .

The NSPL relates both current and terminated postcodes to a range of current statutory geographies via ‘best-fit’ allocation from the 2011 Census Output Areas (national parks and Workplace Zones are exempt from ‘best-fit’ and use ‘exact-fit’ allocations). It supports the production of area based statistics from postcoded data.

The NSPL relates both current and terminated postcodes to a range of current statutory geographies via ‘best-fit’ allocation from the 2021 Census Output Areas (national parks and Workplace Zones are exempt from ‘best-fit’ and use ‘exact-fit’ allocations) for England, Wales, Scotland and Northern Ireland. It supports the production of area-based statistics from postcoded data. The NSPL is produced by ONS Geography, who provide geographic support to the Office for National Statistics (ONS) and geographic services used by other organisations. The NSPL is issued quarterly.

The NSPL relates both current and terminated postcodes to a range of current statutory geographies via ‘best-fit’ allocation from the 2011 Census Output Areas (national parks and Workplace Zones are exempt from ‘best-fit’ and use ‘exact-fit’ allocations). It supports the production of area based statistics from postcoded data. The NSPL is produced by ONS Geography, who provide geographic support to the Office for National Statistics (ONS) and geographic services used by other organisations. The NSPL is issued quarterly .

PLEASE READ THE USER GUIDE AND THE README.TXT FILE This file contains the National Statistics Postcode Lookup (NSPL) for the United Kingdom as at February 2018 in Comma Separated Variable (CSV) and ASCII text (TXT) formats . To download the zip file click the Download button. The NSPL relates both current and terminated postcodes to a range of current statutory geographies via ‘best-fit’ allocation from the 2011 Census Output Areas (national parks and Workplace Zones are exempt from ‘best-fit’ and use ‘exact-fit’ allocations). It supports the production of area based statistics from postcoded data. The NSPL is produced by ONS Geography, who provide geographic support to the Office for National Statistics (ONS) and geographic services used by other organisations. The NSPL is issued quarterly .

To download the zip file click the Download button. The NSPL relates both current and terminated postcodes to a range of current statutory geographies via ‘best-fit’ allocation from the 2011 Census Output Areas (national parks and Workplace Zones are exempt from ‘best-fit’ and use ‘exact-fit’ allocations). It supports the production of area based statistics from postcoded data. The NSPL is produced by ONS Geography, who provide geographic support to the Office for National Statistics (ONS) and geographic services used by other organisations. The NSPL is issued quarterly .

To download the zip file click the Download button. The NSPL relates both current and terminated postcodes to a range of current statutory geographies via ‘best-fit’ allocation from the 2011 Census Output Areas (national parks and Workplace Zones are exempt from ‘best-fit’ and use ‘exact-fit’ allocations). It supports the production of area based statistics from postcoded data. The NSPL is produced by ONS Geography, who provide geographic support to the Office for National Statistics (ONS) and geographic services used by other organisations. The NSPL is issued quarterly .

It supports the production of area based statistics from postcoded data.

The NSPL relates both current and terminated postcodes to a range of current statutory geographies via ‘best-fit’ allocation from the 2011 Census Output Areas (national parks and Workplace Zones are exempt from ‘best-fit’ and use ‘exact-fit’ allocations). It supports the production of area based statistics from postcoded data. The NSPL is produced by ONS Geography, who provide geographic support to the Office for National Statistics (ONS) and geographic services used by other organisations. The NSPL is issued quarterly .

To download the zip file click the Download button. The NSPL relates both current and terminated postcodes to a range of current statutory geographies via ‘best-fit’ allocation from the 2021 Census Output Areas (national parks and Workplace Zones are exempt from ‘best-fit’ and use ‘exact-fit’ allocations) for England, Wales, Scotland and Northern Ireland. It supports the production of area-based statistics from postcoded data. The NSPL is produced by ONS Geography, who provide geographic support to the Office for National Statistics (ONS) and geographic services used by other organisations. The NSPL is issued quarterly. (File size - 196 MB). N.B. From now onwards this will be known simply as the National Statistics Postcode Lookup (NSPL).",

To download the zip file click the Download button. The NSPL relates both current and terminated postcodes to a range of current statutory geographies via ‘best-fit’ allocation from the 2021 Census Output Areas (national parks and Workplace Zones are exempt from ‘best-fit’ and use ‘exact-fit’ allocations) for England, Wales, Scotland and Northern Ireland. It supports the production of area-based statistics from postcoded data. The NSPL is produced by ONS Geography, who provide geographic support to the Office for National Statistics (ONS) and geographic services used by other organisations. The NSPL is issued quarterly.

It supports the production of area-based statistics from postcoded data. The NSPL is produced by ONS Geography, who provide geographic support to the Office for National Statistics (ONS) and geographic services used by other organisations. The NSPL is issued quarterly.

The NSPL relates both current and terminated postcodes to a range of current statutory geographies via ‘best-fit’ allocation from the 2011 Census Output Areas (national parks and Workplace zones are exempt from ‘best-fit’ and use ‘exact-fit’ allocations). It supports the production of area based statistics from postcoded data. The NSPL is produced by ONS Geography, which provides geographic support to the Office for National Statistics (ONS) and geographic services used by other organisations. The NSPL is issued quarterly.

To download the zip file click the Download button. The NSPL relates both current and terminated postcodes to a range of current statutory geographies via ‘best-fit’ allocation from the 2011 Census Output Areas (national parks and Workplace Zones are exempt from ‘best-fit’ and use ‘exact-fit’ allocations). It supports the production of area based statistics from postcoded data. The NSPL is produced by ONS Geography, who provide geographic support to the Office for National Statistics (ONS) and geographic services used by other organisations. The NSPL is issued quarterly .

The NSPL relates both current and terminated postcodes to a range of current statutory geographies via ‘best-fit’ allocation from the 2011 Census Output Areas (national parks and Workplace Zones are exempt from ‘best-fit’ and use ‘exact-fit’ allocations). It supports the production of area based statistics from postcoded data. The NSPL is produced by ONS Geography, who provide geographic support to the Office for National Statistics (ONS) and geographic services used by other organisations. The NSPL is issued quarterly .

To download the zip file click the Download button. The NSPL relates both current and terminated postcodes to a range of current statutory geographies via ‘best-fit’ allocation from the 2011 Census Output Areas (national parks and Workplace Zones are exempt from ‘best-fit’ and use ‘exact-fit’ allocations). It supports the production of area based statistics from postcoded data. The NSPL is produced by ONS Geography, who provide geographic support to the Office for National Statistics (ONS) and geographic services used by other organisations. The NSPL is issued quarterly .

The NSPL relates both current and terminated postcodes to a range of current statutory geographies via ‘best-fit’ allocation from the 2011 Census Output Areas (national parks and Workplace Zones are exempt from ‘best-fit’ and use ‘exact-fit’ allocations). It supports the production of area based statistics from postcoded data. The NSPL is produced by ONS Geography, who provide geographic support to the Office for National Statistics (ONS) and geographic services used by other organisations. The NSPL is issued quarterly .

This file replaces the Clinical Commissioning Group to NHS Region (Geography) to NHS Commissioning Region (April 2017) Lookup in England file. The version 3 of the lookup supersedes the previous version of the same name and contains: We were notified of a late CCG change between NHS Norwich CCG and NHS South Norfolk CCG. Eight LSOAs were moved from NHS South Norfolk CCG to NHS Norwich CCG. The eight LSOAs were E01026895, E01033538, E01033540, E01026924, E01026925, E01026916, E01026917 and E01026918 and have now been allocated to NHS Norwich CCG and the lookup have been recreated as V3. Please note that NHS Norwich CCG (E38000218) and NHS South Norfolk CCG (E38000219) have new 9 character codes. (09/05/2017). Previous corrections include: The newly formed clinical commissioning groups - NHS Cumbria CCG (E38000215), NHS Morecambe Bay CCG (E38000216) and NHS Manchester CCG (E38000217). The newly formed NHS England (Region, Local Office) - NHS England North (Cumbria and North East) (E39000039) and NHS England North (Lancashire and South Cumbria) (E39000040) A name change for NHS Cumbria CCG to NHS North Cumbria CCG (05/05/2017) Organisation Data Service, part of NHS Digital, received formal confirmation from NHS England that they wished to update the collective organisation role/type names for the NHS Region (Geography) and Commissioning Region areas. The new name for these geography entities are NHS England (Region, Local Office) and NHS England (Region), respectively. This is purely a change to organisation role names. The associated organisation role codes, and the names and codes of individual organisations of this type, will all remain unchanged.

The eight LSOAs were E01026895, E01033538, E01033540, E01026924, E01026925, E01026916, E01026917 and E01026918 and have now been allocated to NHS Norwich CCG and the lookup have been recreated as V3. Please note that NHS Norwich CCG (E38000218) and NHS South Norfolk CCG (E38000219) have new 9 character codes. (09/05/2017). Previous corrections include: The newly formed clinical commissioning groups - NHS Cumbria CCG (E38000215), NHS Morecambe Bay CCG (E38000216) and NHS Manchester CCG (E38000217) and means that NHS Cumbria CCG is not split between two STPs.

To that end, the data provided for regions includes Monmouthshire within the “Welsh counties”. However, for the purposes of the 1921 Census outputs, Monmouthshire was generally included within England. In some of the printed tables, figures were given for both “England including Monmouthshire” and “England excluding Monmouthshire”, likewise for Wales. These additional breakdowns are not being included within the digitised data at this time and for the purposes of dissemination on Nomis, Monmouthshire has been included within England only to align with the majority of printed tables. As such, any user aggregated data from regions to country will not match figures given for England and for Wales on Nomis.",

          "In order to protect against disclosure of personal information from the 2011 Census, there has been swapping of records in the Census database between different geographic areas, and so some counts will be affected. In the main, the greatest effects will be at the lowest geographies, since the record swapping is targeted towards those households with unusual characteristics in small areas. More details on the ONS Census disclosure control strategy may be found on the http://www.ons.gov.uk/ons/guide-method/census/2011/census-data/2011-census-prospectus/new-developments-for-2011-census-results/statistical-disclosure-control/index.html[Statistical Disclosure Control] page on the ONS web site.",
          "This dataset provides 2011 Census estimates that classify usual residents aged 16 and over in employment the week before the census in Wales by ability to speak Welsh by industry. The estimates are as at census day, 27 March 2011. This information helps public bodies to understand the extent to which the Welsh language is used and, therefore, to meet their statutory duties under the Welsh Language Act 1993. It is also used for policy development and monitoring, and provides data for the allocation of grants to support the Welsh language. This information is used to assign a code to the industry an individual works in using the UK Standard Industrial Classification of Economic Activities (UKSIC). This enhances the quality of occupation coding and is required at a local level to understand economic performance and analyse local labour markets. It also provides information for policy development and monitoring land use, transport and housing needs."

In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

In the main, the greatest effects will be at the lowest geographies, since the record swapping is targeted towards those households with unusual characteristics in small areas. More details on the ONS Census disclosure control strategy may be found on the http://www.ons.gov.uk/ons/guide-method/census/2011/census-data/2011-census-prospectus/new-developments-for-2011-census-results/statistical-disclosure-control/index.html[Statistical Disclosure Control] page on the ONS web site.",
          "This dataset provides 2011 estimates that classify occupied household spaces in England and Wales by the types of central heating present. The estimates are as at census day, 27 March 2011. The central heating classifications used in this dataset follow the single tick box options on the questionnaire with an additional category for multiple tick options. Although similar to the estimates provided from the 2001 Census in table UV60, central heating was grouped with other household amenities and did not provide this level of detail. This information will support work on housing deprivation where access to central heating is used as a measure of deprivation. It will also contribute to work being undertaken by both central and local government; to meet the thermal comfort criteria of the decent homes standard; related work on assessing housing fitness; development of policies to improve housing quality; and to direct resources to the areas of greatest need."

          "In order to protect against disclosure of personal information from the 2011 Census, there has been swapping of records in the Census database between different geographic areas, and so some counts will be affected. In the main, the greatest effects will be at the lowest geographies, since the record swapping is targeted towards those households with unusual characteristics in small areas. More details on the ONS Census disclosure control strategy may be found on the http://www.ons.gov.uk/ons/guide-method/census/2011/census-data/2011-census-prospectus/new-developments-for-2011-census-results/statistical-disclosure-control/index.html[Statistical Disclosure Control] page on the ONS web site.",
          "This dataset provides 2011 estimates that classify occupied household spaces in England and Wales by the types of central heating present. The estimates are as at census day, 27 March 2011. The central heating classifications used in this dataset follow the single tick box options on the questionnaire with an additional category for multiple tick options. Although similar to the estimates provided from the 2001 Census in table UV60, central heating was grouped with other household amenities and did not provide this level of detail. This information will support work on housing deprivation where access to central heating is used as a measure of deprivation. It will also contribute to work being undertaken by both central and local government; to meet the thermal comfort criteria of the decent homes standard; related work on assessing housing fitness; development of policies to improve housing quality; and to direct resources to the areas of greatest need. Data for Northern Ireland comes from table KS404NI."

In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

In the main, the greatest effects will be at the lowest geographies, since the record swapping is targeted towards those households with unusual characteristics in small areas.

In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

More details on the ONS Census disclosure control strategy may be found on the http://www.ons.gov.uk/ons/guide-method/census/2011/census-data/2011-census-prospectus/new-developments-for-2011-census-results/statistical-disclosure-control/index.html[Statistical Disclosure Control] page on the ONS web site."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

          "Sometimes we need to make changes to data if it is possible to identify individuals. This is known as statistical disclosure control. In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation.",
          "This dataset provides Census 2021 estimates that classify usual residents aged 16 years and over in employment the week before the census in England and Wales by the distance they travelled to work. The estimates are as at Census Day, 21 March 2021. Census 2021 took place during a period of rapid change. We gave extra guidance to help people on furlough answer the census questions about work. However, we are unable to determine how furloughed people followed the guidance. Take care when using this data for planning purposes. Read more about specific quality considerations in our [Labour market quality information for Census 2021 methodology](https://www.ons.gov.uk/employmentandlabourmarket/peopleinwork/employmentandemployeetypes/methodologies/traveltoworkqualityinformationforcensus2021). National Park data are created by plotting unique properties as identified by their Unique Property Reference Number or postcodes into National Park boundaries current at December 2022. This differs from the OA best fit methodology used for other geographic level data."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

          "Sometimes we need to make changes to data if it is possible to identify individuals. This is known as statistical disclosure control. In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation.",

In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

More details on the ONS Census disclosure control strategy may be found on the http://www.ons.gov.uk/ons/guide-method/census/2011/census-data/2011-census-prospectus/new-developments-for-2011-census-results/statistical-disclosure-control/index.html[Statistical Disclosure Control] page on the ONS web site."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

          "Sometimes we need to make changes to data if it is possible to identify individuals. This is known as statistical disclosure control. In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation.",
          "This dataset provides Census 2021 estimates that classify usual residents aged 16 years and over in England and Wales by gender identity. The estimates are as at Census Day, 21 March 2021. Gender identity estimates from Census 2021 are official statistics in development. Quality work has been completed to provide more detailed information on the uncertainty associated with the Census 2021 gender identity estimates and guidance can be found in Census 2021 gender identity estimates for England and Wales [additional guidance on uncertainty and appropriate use](https://www.ons.gov.uk/peoplepopulationandcommunity/culturalidentity/genderidentity/articles/census2021genderidentityestimatesforenglandandwalesadditionalguidanceonuncertaintyandappropriateuse/2025-03-26).

          "Sometimes we need to make changes to data if it is possible to identify individuals. This is known as statistical disclosure control. In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation.",

In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation.",

          "Sometimes we need to make changes to data if it is possible to identify individuals. This is known as statistical disclosure control. In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation.",

The estimates are as at Census Day, 21 March 2021. Gender identity estimates from Census 2021 are official statistics in development. Quality work has been completed to provide more detailed information on the uncertainty associated with the Census 2021 gender identity estimates and guidance can be found in Census 2021 gender identity estimates for England and Wales [additional guidance on uncertainty and appropriate use](https://www.ons.gov.uk/peoplepopulationandcommunity/culturalidentity/genderidentity/articles/census2021genderidentityestimatesforenglandandwalesadditionalguidanceonuncertaintyandappropriateuse/2025-03-26).

          "Sometimes we need to make changes to data if it is possible to identify individuals. This is known as statistical disclosure control. In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation.",

          "Sometimes we need to make changes to data if it is possible to identify individuals. This is known as statistical disclosure control. In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation.",
          "This dataset provides Census 2021 estimates that classify usual residents aged 16 years and over in England and Wales by gender identity and ethnic group. The estimates are as at Census Day, 21 March 2021. Gender identity estimates from Census 2021 are official statistics in development. Quality work has been completed to provide more detailed information on the uncertainty associated with the Census 2021 gender identity estimates and guidance can be found in Census 2021 gender identity estimates for England and Wales [additional guidance on uncertainty and appropriate use](https://www.ons.gov.uk/peoplepopulationandcommunity/culturalidentity/genderidentity/articles/census2021genderidentityestimatesforenglandandwalesadditionalguidanceonuncertaintyandappropriateuse/2025-03-26). Please refer to the [Sexual Orientation and Gender Identity Quality Information page](https://www.ons.gov.uk/peoplepopulationandcommunity/culturalidentity/sexuality/methodologies/sexualorientationandgenderidentityqualityinformationforcensus2021) before using these estimates."

          "Sometimes we need to make changes to data if it is possible to identify individuals. This is known as statistical disclosure control. In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation.",

In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation.",

          "Sometimes we need to make changes to data if it is possible to identify individuals. This is known as statistical disclosure control. In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation.",
          "This dataset provides Census 2021 estimates that classify usual residents aged 16 years and over in employment the week before the census in England and Wales, by gender identity and hours worked. The estimates are as at Census Day, 21 March 2021. Gender identity estimates from Census 2021 are official statistics in development. Quality work has been completed to provide more detailed information on the uncertainty associated with the Census 2021 gender identity estimates and guidance can be found in Census 2021 gender identity estimates for England and Wales [additional guidance on uncertainty and appropriate use](https://www.ons.gov.uk/peoplepopulationandcommunity/culturalidentity/genderidentity/articles/census2021genderidentityestimatesforenglandandwalesadditionalguidanceonuncertaintyandappropriateuse/2025-03-26).

          "Sometimes we need to make changes to data if it is possible to identify individuals. This is known as statistical disclosure control. In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation.",

          "Sometimes we need to make changes to data if it is possible to identify individuals. This is known as statistical disclosure control. In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation.",
          "This dataset provides Census 2021 estimates that classify usual residents aged 16 years and over in England and Wales, by gender identity and industry. The estimates are as at Census Day, 21 March 2021. Gender identity estimates from Census 2021 are official statistics in development. Quality work has been completed to provide more detailed information on the uncertainty associated with the Census 2021 gender identity estimates and guidance can be found in Census 2021 gender identity estimates for England and Wales [additional guidance on uncertainty and appropriate use](https://www.ons.gov.uk/peoplepopulationandcommunity/culturalidentity/genderidentity/articles/census2021genderidentityestimatesforenglandandwalesadditionalguidanceonuncertaintyandappropriateuse/2025-03-26).

          "Sometimes we need to make changes to data if it is possible to identify individuals. This is known as statistical disclosure control. In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation.",

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

          "Sometimes we need to make changes to data if it is possible to identify individuals. This is known as statistical disclosure control. In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation.",

In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation.",

          "Sometimes we need to make changes to data if it is possible to identify individuals. This is known as statistical disclosure control. In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation.",

The estimates are as at Census Day, 21 March 2021. Gender identity estimates from Census 2021 are official statistics in development. Quality work has been completed to provide more detailed information on the uncertainty associated with the Census 2021 gender identity estimates and guidance can be found in Census 2021 gender identity estimates for England and Wales [additional guidance on uncertainty and appropriate use](https://www.ons.gov.uk/peoplepopulationandcommunity/culturalidentity/genderidentity/articles/census2021genderidentityestimatesforenglandandwalesadditionalguidanceonuncertaintyandappropriateuse/2025-03-26).

          "Sometimes we need to make changes to data if it is possible to identify individuals. This is known as statistical disclosure control. In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation.",

          "Sometimes we need to make changes to data if it is possible to identify individuals. This is known as statistical disclosure control. In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation.",
          "This dataset provides Census 2021 estimates that classify usual residents aged 16 years and over in England and Wales, by gender identity and religion. The estimates are as at Census Day, 21 March 2021. Gender identity estimates from Census 2021 are official statistics in development. Quality work has been completed to provide more detailed information on the uncertainty associated with the Census 2021 gender identity estimates and guidance can be found in Census 2021 gender identity estimates for England and Wales [additional guidance on uncertainty and appropriate use](https://www.ons.gov.uk/peoplepopulationandcommunity/culturalidentity/genderidentity/articles/census2021genderidentityestimatesforenglandandwalesadditionalguidanceonuncertaintyandappropriateuse/2025-03-26). Please refer to the [Sexual Orientation and Gender Identity Quality Information page](https://www.ons.gov.uk/peoplepopulationandcommunity/culturalidentity/sexuality/methodologies/sexualorientationandgenderidentityqualityinformationforcensus2021) before using these estimates."

          "Sometimes we need to make changes to data if it is possible to identify individuals. This is known as statistical disclosure control. In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation.",

In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation.",

          "Sometimes we need to make changes to data if it is possible to identify individuals. This is known as statistical disclosure control. In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation.",
          "This dataset provides Census 2021 estimates that classify usual residents aged 16 years and over in households in England and Wales, by gender identity and tenure. The estimates are as at Census Day, 21 March 2021. Gender identity estimates from Census 2021 are official statistics in development. Quality work has been completed to provide more detailed information on the uncertainty associated with the Census 2021 gender identity estimates and guidance can be found in Census 2021 gender identity estimates for England and Wales [additional guidance on uncertainty and appropriate use](https://www.ons.gov.uk/peoplepopulationandcommunity/culturalidentity/genderidentity/articles/census2021genderidentityestimatesforenglandandwalesadditionalguidanceonuncertaintyandappropriateuse/2025-03-26).

          "Sometimes we need to make changes to data if it is possible to identify individuals. This is known as statistical disclosure control. In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation.",

In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation.",

In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

          "Sometimes we need to make changes to data if it is possible to identify individuals. This is known as statistical disclosure control. In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

In the main, the greatest effects will be at the lowest geographies, since the record swapping is targeted towards those households with unusual characteristics in small areas.

In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

          "Sometimes we need to make changes to data if it is possible to identify individuals. This is known as statistical disclosure control. In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

          "Sometimes we need to make changes to data if it is possible to identify individuals. This is known as statistical disclosure control. In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

          "Sometimes we need to make changes to data if it is possible to identify individuals. This is known as statistical disclosure control. In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

More details on the ONS Census disclosure control strategy may be found on the http://www.ons.gov.uk/ons/guide-method/census/2011/census-data/2011-census-prospectus/new-developments-for-2011-census-results/statistical-disclosure-control/index.html[Statistical Disclosure Control] page on the ONS web site."

          "Sometimes we need to make changes to data if it is possible to identify individuals. This is known as statistical disclosure control. In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation.",
          "This dataset provides Census 2021 estimates that classify usual residents in England and Wales by their method used to travel to work (2001 specification). The estimates are as at Census Day, 21 March 2021. Census 2021 took place during a period of rapid change. We gave extra guidance to help people on furlough answer the census questions about work. However, we are unable to determine how furloughed people followed the guidance. Take care when using this data for planning purposes.

In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

More details on the ONS Census disclosure control strategy may be found on the http://www.ons.gov.uk/ons/guide-method/census/2011/census-data/2011-census-prospectus/new-developments-for-2011-census-results/statistical-disclosure-control/index.html[Statistical Disclosure Control] page on the ONS web site."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

In the main, the greatest effects will be at the lowest geographies, since the record swapping is targeted towards those households with unusual characteristics in small areas.

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

          "Sometimes we need to make changes to data if it is possible to identify individuals. This is known as statistical disclosure control. In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

In Census 2021, we: * Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation."

Very unusual households could be swapped with one in a nearby local authority. * Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five.
