Mid Year Population Estimates

Estimates of the population of Northern Ireland as of 30 June each year by age and sex.

NISRA released the first phase of main statistics from Census 2021 on 22 September 2022. The census population of Northern Ireland on 21 March 2021 was 1,903,175 people, which was 0.2 per cent higher than our 2020 mid-year population estimate rolled forward to March 2021 (1,898,600).

NISRA population statistics published the 2021 mid-year population and migration estimates for Northern Ireland and the 11 Local Government Districts rolled forward from Census 2021 on 29 November 2022.

Following the publication of the 2021 mid-year population estimates, NISRA population statistics will then undertake a rebasing exercise to revise the population estimates time series from 2012 to 2020 in line with the most recent Census 2021 population estimates. This exercise will be completed by spring 2023.
