The census collects information every 10 years about people and households in Northern Ireland. It is used by central and local government, health authorities and many other organisations to plan and provide future services. 

The census rehearsal is coming to an end. Online sumbissions have now closed. You can still return your paper form to be counted. In doing so, you'll help us make sure Census 2021 runs smoothly and represents everyone. Find out more about the census
