Census 2021 rounded population and household estimates for local authorities in England and Wales, by sex and five-year age group.

This dataset provides Census 2021 estimates that classify usual residents in England and Wales by their country of birth, this dataset comprises a more detailed breakdown of birth country. The estimates are as at Census Day, 21 March 2021.

Census 2021 rounded migration estimates for local authorities in England and Wales were originally released on 28 June 2022 in rounded form. The bulletin explored change over time, regional variations and the composition of the population by sex and by five-year age group.

This update provides unrounded migration estimates from Country level down to Output Area.

Area type

Census 2021 statistics are published for a number of different geographies. These can be large, for example the whole of England, or small, for example an output area (OA), the lowest level of geography for which statistics are produced.

For higher levels of geography, more detailed statistics can be produced. When a lower level of geography is used, such as output areas (which have a minimum of 100 persons), the statistics produced have less detail. This is to protect the confidentiality of people and ensure that individuals or their characteristics cannot be identified.

Coverage

Census 2021 statistics are published for the whole of England and Wales. Data are also available in these geographic types:

• country - for example, Wales
• region - for example, London
• local authority - for example, Cornwall
• health area – for example, Clinical Commissioning Group
• statistical area - for example, MSOA or LSOA

Country of birth

The country in which a person was born.

For people not born in one of in the four parts of the UK, there was an option to select "elsewhere".

People who selected "elsewhere" were asked to write in the current name for their country of birth.

Estimates of London's population between 1801 and 2001 (persons present 1801 to 1991 and residents for 2001 onwards) derived from historic Census data.

Sources: years to 1971 - Greater London Council Research Memorandum 413, The Changing Population of the London Boroughs; 1981 Census Small Area Statistics, Table 1; 1991 Census Small Area Statistics, Table 1. Figure for Year-1939 is a mid-year estimate for the year 1939. Figure for Year-2001 onwards is the number of residents because the number of persons present is not available from 2001. Note that totals for Greater London may not match due to rounding errors. Figures are estimates to the nearest thousand.

Lower Tier Local Authorities

Lower tier local authorities provide a range of local services. In England there are 309 lower tier local authorities. These are made up of non-metropolitan districts (181), unitary authorities (59), metropolitan districts (36) and London boroughs (33, including City of London). In Wales there are 22 local authorities made up of 22 unitary authorities. Of these local authority types, only non-metropolitan districts are not additionally classified as upper tier local authorities.

About this dataset

Context

The dataset tabulates the London population distribution across 18 age groups. It lists the population in each age group along with the percentage population relative of the total population for London. The dataset can be utilized to understand the population distribution of London by age. For example, using this dataset, we can identify the largest age group in London.

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.

The Great Britain Historical GIS Project has also produced digitised boundary data, which can be obtained from the UK Data Service Census Support service. Further information is available at census.ukdataservice.ac.uk

Main Topics:

The Great Britain Historical Database is a large database of British nineteenth and twentieth-century statistics. Where practical the referencing of spatial units has been integrated, data for different dates have been assembled into single tables.

The Great Britain Historical Database currently contains :

• Statistics from the 1861 Census and the Registrar General's reports, 1851-1861
  
• Employment statistics from the census, 1841-1931
  
• Demographic statistics from the census, 1841-1931
  
• Mortality statistics from the Registrar General's reports, 1861-1920
  
• Marriage statistics from the Registrar General's reports, 1841-1870
  
• Trade union statistics for the Amalgamated Society of Engineers (ASE), 1851-1918
  
• Trade union statistics for the Amalgamated Society of Carpenters and Joiners (ASCJ), 1863-1912
  
• Official poor law statistics, 1859-1915 and 1919-1939
  
• Wage statistics, 1845-1906
  
• Hours of work statistics, 1900-1913
  
• Small debt statistics from county courts, 1847-1913 and 1938
  

There are six tables in this part of the Great Britain Historical Database :

Lee_emp holds simplified and standardised versions of the country-level employment statistics for Great Britain given in the printed census reports from 1841 to 1931, using the employment categories defined by the Standard Industrial Classification.

Emp1901m holds male employment statistics from the 1901 census for county boroughs, municipal boroughs and urban districts over 10,000 population in England and Wales.

Emp1901f holds female employment statistics from the 1901 census for county boroughs, municipal boroughs and urban districts over 10,000 population in England and Wales.

Emp1911m holds male employment statistics from the 1911 census for counties, county boroughs, municipal boroughs and urban districts over 10,000 population in England and Wales.

Emp1911f holds female employment statistics from the 1911 census for counties, county boroughs, municipal boroughs and urban districts over 10,000 population in England and Wales.

Emp1921 holds male and female employment statistics from the 1921 census for county boroughs, municipal boroughs, urban districts and rural districts, plus certain civil parishes in England and Wales.

Please note: this study does not include information on named individuals and would therefore not be useful for personal family history research.

This dataset provides Census 2021 estimates that classify usual residents in England and Wales by sex and single year of age. The estimates are as at Census Day, 21 March 2021.

The classifications for the datasets TS009 Sex by single year of age and RM200 Sex by single year of age (detailed) are the same. However, RM200 has data available at the lower geographies of:

• Lower layer Super Output Areas (LSOAs)
• Middle layer Super Output Areas (MSOAs)
• Electoral wards and divisions
• Westminster parliamentary constituencies

Estimates for single year of age between ages 90 and 100+ are less reliable than other ages. Estimation and adjustment at these ages was based on the age range 90+ rather than five-year age bands.
