The Northern Ireland Statistics and Research Agency (NISRA) have released results for Census 2021. View the results on the NISRA website (opens in a new tab) .

What is the census?

The census happens only once every 10 years. It gives us the most accurate estimate of all the people and households in Northern Ireland. The information you give us helps decide how services are planned and funded in your local area. This could mean things like doctors’ surgeries, housing or new bus routes.

It asks questions about you and your household to build a picture of us all. It looks at who we are and how we live. It provides vital information about us, our society and future needs.

We have had a great response to the 2021 Census from households across Northern Ireland, thank you to all who took part.
