About this dataset
This dataset provides Census 2021 estimates that classify usual residents in Wales aged 3 years and over in Wales by ability to speak Welsh, by national identity, and by age. The estimates are as at Census Day, 21 March 2021.
Protecting personal data
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.

About the variables
National identity (9 categories)
Description: Someone's national identity is a self-determined assessment of their own identity, it could be the country or countries where they feel they belong or think of as home. It is not dependent on ethnic group or citizenship. Respondents could select more than one national identity.
Quality information: The increase since the 2011 Census in people identifying as 'British' and fall in people identifying as 'English' may partly reflect true changes in self-perception. It is also likely to reflect that 'British' replaced 'English' as the first response option listed on the questionnaire in England.
Comparability with 2011: Broadly comparable. This derived variable can be generally compared with the same variable used in the 2011 Census, but there are some quality issues in the data.
Read more...Age (4 categories)
Description: A person's age on Census Day, 21 March 2021 in England and Wales.
Quality information: 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.
Comparability with 2011: Highly comparable
Read more...Welsh speaking ability (3 categories)
Description: This classifies a person as being able to "Speak Welsh". They may have also ticked one or more of the following: * understand spoken Welsh * read Welsh * write Welsh
In results that classify people by Welsh language skills, a person may appear in more than one category depending on which combination of skills they have.
Comparability with 2011: Highly comparable
