Mid Year Population Estimates

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

After each Census mid-year population estimates are reviewed. These reviews look at the process used to generate mid-year population estimates, to validate the published data and produce the most robust mid-year population estimate time series.  With Census 2021 the mid-year estimates and their time series will again be reviewed, and any revisions published. It is currently planned that this review will look at the series from 1971 to 2021. Users should be aware that the current series is consistent for the period 1981-2018.
