The Population Statistics Section within Census Branch (NISRA) provides accurate, timely, user friendly and easily accessible National Statistics relating to Population Estimates, Projections and Migration for Northern Ireland.

Population statistics are widely used in policy development in areas such as housing, healthcare and education, as well as being used to allocate public funds to the Northern Ireland Executive through the Barnett formula.

These statistics are also of interest to those involved in research & academia. They are widely used to express other statistics as a rate and thus enable comparisons across the United Kingdom and other countries.

Generally, population statistics are available disaggregated by age and sex with information also available for a wide range of administrative and statistical geographies.

Further information on the statistics that we produce is available within our main publications summary. Our 2022/23 work plan is available here.

For key statistics relating to population estimates, explore the population statistics dashboard.
