2020-based Interim Population Projections for Northern Ireland

Date published: 12 January 2022


National projections by sex and single year of age are produced every two years for the UK and each of the UK constituent countries by the Office for National Statistics (ONS). National projections provide an estimate of the future size and age structure of the population of Northern Ireland.


This release includes the following documents:

  • Statistical bulletin
  • Infographic summary

and the following tables (for the Principal Projection):

  • Projection summary (2020-2070)
  • Single year of age and sex (2020-2070)
  • 5 year age bands and sex (2020-2070)

A processing error was identified which affects international out migration from Wales in the 2020-based national population projections. This affects the age and sex distributions of the international out migration from Wales only. There is minimal impact on the Northern Ireland projections. We will therefore not be changing the projections or issuing a corrected version because of the small magnitude of this error which is within the inherent uncertainty seen around projections and underlying estimates. Further details can be found on the ONS website.
