Population and household estimates

These first results from Census 2021 provide the usual resident population and number of households in Northern Ireland.

The population estimates in the 24 May 2022 release were published rounded to the nearest 100 because at that time the dataset was still being subjected to a number of final statistical procedures. The statistics in ‘Census 2021 main statistics for Northern Ireland (phase 1)’ reflect the final database.
