2021 census data is being published for England, Wales, and Northern Ireland across 2022 and 2023.

The census asked people about topics including their background (such as ethnicity, religion, and sexual orientation), housing, health, and work.

This page brings together our constituency data dashboards and other analysis of 2021 census results. We’ll release publications on new topics here as data becomes available.
