Abstract copyright UK Data Service and data collection copyright owner.The 2021 UK Census was the 23rd official census of the United Kingdom. The UK Census is generally conducted once every 10 years, and the 2021 censuses of England, Wales, and Northern Ireland took place on 21 March 2021. In Scotland, the decision was made to move the census to March 2022 because of the impact of the coronavirus pandemic. The censuses were administered by the Office for National Statistics (ONS), the Northern Ireland Statistics and Research Agency (NISRA) and National Records of Scotland (NRS), respectively. In England and Wales, Census 2021 was the first census with a digital-first design, encouraging participants to respond online rather than on a paper questionnaire.Topics covered in the 2021 UK Census included:demography and migrationethnic group, national identity, language and religionlabour market and travel to workhousingeducationhealth, disability, and unpaid careWelsh and other languagesUK armed forces veteranssexual orientation and gender identity. The 2021 Census: Safeguarded Individual Microdata Sample at Region Level dataset consists of a random sample of 5% of person records from the 2021 Census. It includes records for 3,021,455 persons. These data cover England and Wales only. The lowest level of geography is country (Wales) and regions within England. The dataset contains 89 variables and a medium level of detail.Census MicrodataMicrodata are small samples of individual records from a single census from which identifying information have been removed. They contain a range of individual and household characteristics and can be used to carry out analysis not possible from standard census outputs, such as:creating tables using bespoke variable combinationsinvestigating specific combinations of variables or categories in a high level of detailconducting non-tabular statistical analyses on record-level data.The microdata samples are designed to protect the confidentiality of individuals and households. This is done by applying access controls and removing information that might directly identify a person, such as names, addresses and date of birth. Record swapping is applied to the census data used to create the microdata samples. This is a statistical disclosure control (SDC) method, which makes very small changes to the data to prevent the identification of individuals. The microdata samples use further SDC methods, such as collapsing variables and restricting detail. The samples also include records that have been edited to prevent inconsistent data and contain imputed persons, households, and data values. To protect confidentiality, imputation flags are not included in any 2021 Census microdata sample.

Paper questionnaire used in the 2021 Census, from which you can see the questions that were asked and the directions used to help filling it in.

The UK's contribution of census data to the United Nations project, United Nations Questionnaires on Population and Housing Census.

This dataset represents ethnic group (19 tick-box level) by economic activity status and by occupation, for England and Wales combined. The census data are also broken down by age and by sex for each subtopic.

The ethnic group that the person completing the census feels they belong to. This could be based on their culture, family background, identity, or physical appearance. Respondents could choose one out of 19 tick-box response categories, including write-in response options.

Total counts for some population groups may not match between published tables. This is to protect the confidentiality of individuals' data. Population counts have been rounded to the nearest 5 and any counts below 10 are suppressed, this is signified by a 'c' in the data tables.

This dataset shows population counts for usual residents aged between 16 to 64 years old only. This is to focus on ethnic groups differences among the working age. Population counts in these tables may be different from other publications which use different age breakdowns.

"Asian Welsh" and "Black Welsh" ethnic groups were included on the census questionnaire in Wales only, these categories were new for 2021.

This dataset provides Census 2021 estimates that classify usual residents in England and Wales by ethnic group. The estimates are as at Census Day, 21 March 2021.

This dataset contains gridded human population with a spatial resolution of 1 km x 1 km for the UK based on Census 2021 (Census 2022 for Scotland) and Land Cover Map 2021 input data. Data on population distribution for the United Kingdom is available from statistical offices in England, Wales, Northern Ireland and Scotland and provided to the public e.g. via the Office for National Statistics (ONS). Population data is typically provided in tabular form or, based on a range of different geographical units, in file types for geographical information systems (GIS), for instance as ESRI Shapefiles. The geographical units reflect administrative boundaries at different levels of detail, from Devolved Administration to Output Areas (OA), wards or intermediate geographies. While the presentation of data on the level of these geographical units is useful for statistical purposes, accounting for spatial variability for instance of environmental determinants of public health requires a more spatially homogeneous population distribution. For this purpose, the dataset presented here combines 2021/2022 UK Census population data on Output Area level with Land Cover Map 2021 land-use classes 'urban' and 'suburban' to create a consistent and comprehensive gridded population data product at 1 km x 1 km spatial resolution. The mapping product is based on British National Grid (OSGB36 datum).

The Great Britain Historical Database has been assembled as part of the ongoing Great Britain Historical GIS Project. The project aims to trace the emergence of the north-south divide in Britain and to provide a synoptic view of the human geography of Britain at sub-county scales. Further information about the project is available on A Vision of Britain webpages, where users can browse the database's documentation system online.

These data were originally collected by the Censuses of Population for England and Wales, and for Scotland. They were computerised by the Great Britain Historical GIS Project and its collaborators. They form part of the Great Britain Historical Database, which contains a wide range of geographically-located statistics, selected to trace the emergence of the north-south divide in Britain and to provide a synoptic view of the human geography of Britain, generally at sub-county scales.

The Census of Population first gathered data on housing "density", i.e. the number of persons in each household relative to the number of rooms, in 1891, although the first year included here is 1901. In 1891, over-crowding was defined as over 2 persons per room; by 1931 this threshold had dropped to 1.5 persons; and by 1961 to 1 person per room. Up to 1931, the data for each locality and date form a table of numbers of persons against numbers of rooms, and these transcriptions sometimes exclude the rows/columns for the very largest households (see the documentation for individual tables). From 1951 onwards, simpler tables simply list numbers of households in each density category (e.g. over 1 person per room and not more than 1.5 persons).

This dataset represents ethnic group (19 tick-box level) by dwelling tenure and by occupancy rating, for England and Wales combined. The data are also broken down by age and by sex.

On 2 November 2022, the Office for National Statistics (ONS) published 'Demography and migration: Census 2021 in England and Wales', which helped form the Welsh Government's publication 'Demography and migration in Wales (Census 2021)'. This was an update to initial population and household estimates, and included an overview of the non-UK born population as well as characteristics of households and residents in Wales. This table is based on Census table TS012, 'Country of Birth (detailed)', which provides Census 2021 estimates that classify usual residents in Wales and England by their country of birth. For Census 2021, the ONS made changes to the data (called statistical disclosure control) so that it is not possible to identify individuals. These changes included: • Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, they 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, 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 perturbation is applied. This causes small changes to cells but does not fundamentally impact the meaning of the data. Where tables are made in different ways, the changes applied will be different, leading to differences between totals and tables not ‘adding-up’ to their totals. To minimise this, the ONS recommends where possible using totals from tables with fewer cells, at higher geographies. For example, if you wanted population by age you should use data from TS007 and if you wanted population by sex you should use data from TS008. More information about the processes used in statistical disclosure control will be provided in future publications. A usual resident of Wales is anyone who was living or staying in Wales for 12 months or longer on Census Day, 21 March 2021, or who had a permanent address in Wales and was staying outside Wales for less than 12 months.

Abstract copyright UK Data Service and data collection copyright owner.The UK censuses took place on 27 March 2011. They were run by the Northern Ireland Statistics & Research Agency (NISRA), National Records of Scotland (NRS), and the Office for National Statistics (ONS) for both England and Wales. The UK comprises the countries of England, Wales, Scotland and Northern Ireland.Statistics from the UK censuses help paint a picture of the nation and how we live. They provide a detailed snapshot of the population and its characteristics and underpin funding allocation to provide public services. This is the home for all UK census data. Census flow data involve flows of individuals in the UK between origins and destinations. These flows are either the residential migrations of individuals from one place of usual residence to another, or of commuters making journeys from home to workplace or place of study. These data are derived from the questions on the census form relating to usual place of residence one year ago, and the place of work for the respondent's main job. Flow data are currently available at a range of different spatial scales ranging from Output Areas to Local Authority Districts. Main Topics: The Census Support: Flow Data website facilitates access to the interaction data for members of UK higher and further education institutions. Access is provided through the Web-based Interface to Census Interaction Data (WICID). The 2011 sets currently held include:Census migration datasets: Special Migration Statistics. Migration data at Local Authority District, Ward, and Output Area level.Special Student Statistics: Migration data at Local Authority District, Ward, and Output Area level.Census commuting datasets: Special Workplace Statistics: Commuting data at Local Authority District, Middle-layer Super Output Area, Intermediate Zone (for Scotland), Workplace Zone (for England and Wales), and Output Area level.Census second residence datasets: Special Residence Statistics. Commuting data at Local Authority District, Ward, and Output Area level.Explicit registration is not required for the 2011 Census products that have been released under the Open Government Licence. However, outputs from the 2011 Census classified as 'safeguarded' require users to agree on additional terms and conditions. Access to these datasets is only permitted via Federated Access.

Abstract copyright UK Data Service and data collection copyright owner.The UK censuses took place on 21st April 1991. They were run by the Census Office for Northern Ireland, General Register Office for Scotland, and the Office of Population and Surveys for both England and Wales. The UK comprises the countries of England, Wales, Scotland and Northern Ireland.Statistics from the UK censuses help paint a picture of the nation and how we live. They provide a detailed snapshot of the population and its characteristics, and underpin funding allocation to provide public services. The aggregate data produced as outputs from censuses in Great Britain provide information on a wide range of demographic and socio-economic characteristics. They are predominantly a collection of aggregated or summary counts of the numbers of people or households resident in specific geographical areas possessing particular characteristics.The topics covered by the 1991 Census were virtually the same as those in the 1981 Census. However, new questions were introduced on limiting long-term illness, ethnic group, central heating and term-time address of students. Also a question on weekly hours worked was re-introduced.The 100% Sample files include information about total population; population in private households and communal establishments; sex; age; marital status; country of birth; ethnicity; migration; employment status; economic activity; household composition; dependent children; dependant adults; long-term illness; household car availability; housing; housing tenure; housing amenities; central heating; linguistic ability (Welsh/Gaelic in Wales and Scotland respectively).The 10% Sample files contain information about socio-economic composition; employment status; occupations; industry of occupation; hours of work; commuting; qualifications, family type; household composition; age; sex; marital status; ethnicity; housing tenure; social class.Local Base Statistics (LBS)The 1991 Census Local Base Statistics (LBS) have around 20,000 statistical counts (cells) contained in 99 tables and cover the complete range of topics in the 1991 Census. They form the basis of the tables to be reproduced for each county (in England and Wales) and region (in Scotland) and for each local authority district. The LBS are available down to ward level in England and Wales and postcode sector level in Scotland.Small Area Statistics (SAS)The 1991 Census Small Area Statistics (SAS) tables are an abbreviated version of the Local Base Statistics. They comprise around 10,000 counts for each area and are available as an abstract of some 86 tables for geographic areas down to Enumeration District level in England and Wales and Output Area level in Scotland.Data can be accessed through CKAN (to bulk download data).Citation: Office of Population Censuses and Surveys; General Register Office for Scotland; Registrar General for Northern Ireland (1997): 1991 Census aggregate data (Edition: 1997).
