About the census
The census happens only once every 10 years and gives us a picture of all the people and households in Northern Ireland.

Help with the census
If you don’t have an access code
You can request a new access code to start a new census if you have lost or not received an access code.
If you need to answer separately from the people you live with, you can request an individual access code to start a separate census.
Someone in your household must still complete a census using a household access code
If you want to fill out a paper census
You can request a paper census questionnaire to be sent in the post.
