Ethnic group, national identity, language and religion : Overview

On 29 November 2022, as part of our topic summaries releases for Census 2021, we published data about people’s ethnic group, national identity, language and religion in England and Wales.

This gives the latest information about:

  • which ethnic groups people identified with
  • the main language people use
  • how well people, who do not have English as a main language, could speak English
  • how people describe their national identity
  • which religious groups people identified with

Welsh ethnic group, national identity, language and religion information

We will provide information in the Welsh language for all Census 2021 topic summaries, and the Welsh Government will release data specifically about Wales.

We've created downloadable PDFs in Welsh for each of the topic summary bulletins about ethnic group, national identity, language and religion. You can download these from each bulletin on the Office for National Statistics (ONS) website.

The Welsh Government will publish Census 2021 topic summaries information that is specific to Wales. The ethnic group, national identity, language and religion release includes the following insights about the population of Wales:
