Comparison of Northern Ireland Statistical Population Dataset with Census 2021

Date published: 19 December 2024

Statistics: Population,  Research into using administrative data for population estimates

This statistical research paper describes how NISRA used a range of administrative data sources to develop the Statistical Population Dataset (SPD).

The aim of the SPD was to approximate the usually resident population by age and sex at the Northern Ireland (NI) and sub-NI geographic levels.

Tables, charts and maps from this publication are available to download.

Disclaimer: The Statistical Population Dataset estimates are statistical research and do not replace the accredited official statistics: the mid-year population estimates.
