Census 2021 data about the Welsh language skills (ability to understand spoken Welsh, speak Welsh, read Welsh, and write Welsh) of people aged three years or older living in Wales.
The Office for National Statistics has published a statistical bulletin about the Welsh language in Wales from Census 2021. It includes data from Census 2021 about the ability of usual residents aged three years and older living in Wales to understand spoken Welsh, and to speak, read or write Welsh.
Information about Welsh language skills in the census is based on a person’s self-assessment of their ability. In some cases, especially for children, Welsh language ability was reported by another person, for example, a parent or guardian.
