Welsh language in Wales

On 6 December 2022, as part of our topic summaries releases for Census 2021, the Welsh Government published data about the Welsh language skills of people aged three or older living in Wales.

What's included in the Census 2021 Welsh language in Wales results

The Census 2021 Welsh language in Wales results include data about the Welsh language skills of people aged three or older living in Wales.

This answers questions like:

  • how has the number of people who said they speak Welsh changed over time?
  • how do the numbers of people who said they speak Welsh vary according to age and across local authorities and small areas?
  • how has the ability of the population to understand spoken Welsh, read Welsh and write Welsh changed over time?

You can find out more about the Welsh language in Wales results on the Welsh Government website.
