• 7th January 2026: Dataset first published.

Main information

• Designation: Accredited official statistics
• Data provider: Office for National Statistics (ONS)
• Data source: 2021 Census

Overview

• Summary of dataset and variables:

  This dataset shows counts and percentages of people in Wales by high level ethnic group and age group for Wales and local authorities. Data is for usual residents from Census 2021. The count shows the number of people of a given ethnic group and age group in an area, the percentage shows the proportion of people in a given ethnic group and age group in an area.

  The ethnic group is that which 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. This dataset shows the five high level ethnic groups: Asian, Asian British or Asian Welsh; Black, Black British, Black Welsh, Caribbean or African; Mixed or Multiple ethnic groups; White; Other ethnic group.

  For Census 2021, a usual resident of the UK is anyone who, on census day, was in the UK and had stayed or intended to stay in the UK for a period of 12 months or more or had a permanent UK address and was outside the UK and intended to be outside the UK for less than 12 months.

• Data collection or calculation:

  Estimates provided are for usual residents as on Census Day, 21 March 2021. The data was collected through questionnaires for every household and communal establishment in Wales. Please see the Office for National Statistics (ONS) quality and methodology information on the 2021 Census for more information - a link is provided in the Related Reports section.

• Statistical quality:

  The census provides the most detailed picture of the entire population, with the same core questions asked to everybody across England and Wales. There is less margin for error in the census than with surveys based on a sample of the population, because the whole population is included.

  Due to statistical disclosure procedures, totals may not exactly match. Sometimes changes need to be made to data if it is possible to identify individuals. This is known as statistical disclosure control. The disclosure control carried out by ONS for Census 2021 included: Swapping records (targeted record swapping). For example, if a household was likely to be identified in datasets because it has unusual characteristics, the records were swapped with a similar one from a nearby small area (very unusual households could be swapped with one in a nearby local authority). Adding small changes to some counts (cell key perturbation). For example, a count of four might be changed to a three or a five – this might make small differences between tables depending on how the data is broken down.
