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 online census has now closed, but it's not too late to take part. You can still complete and return the paper form that we sent you in the post. Visit the Census 2021 to request a new paper form.
Government and the census
It is important to know how many people live in Northern Ireland so that the Government can work out what types of services are needed now and in the future. With statistics from the census, central and local government can allocate funds, decide future policy and plan important services.
You can find out more about the census, including the information collected, how it’s used and how it’s stored on the Northern Ireland Research and Statistics Agency (NISRA) website.
The last census was held on 27 March 2011. You can access the results of the 2011 Census on the Northern Ireland Neighbourhood Information Service (NINIS) website.
You can also access older census results from the NISRA website.
If you want further information on the census you can contact the Census Customer Services team.
