2021 census has question on sexual orientation
People will be encouraged to complete Northern Ireland's next census online.
A question on sexual orientation will be included.
The census is expected to take place on March 21, 2021. Officials said it will be "digital-first". However, paper questionnaires and support will also be available.
In the UK a census is held every 10 years. By law, everyone must take part. All households will receive a census form and must complete it, with information about everyone living there.
Information includes the occupants' age, sex, occupation and educational qualifications.
Plans for the census were published yesterday by the Northern Ireland Research & Statistics Agency.
Siobhan Carey, registrar general for Northern Ireland, said: "The census provides an unparalleled and comprehensive picture of our population. The results are invaluable to help plan and shape public services by effectively targeting resources.
"The digital-first census reflects the changing preferences of our population and will make it easier for people to complete their census at a time that suits them."
