Mid-Year Population Estimates – Urban/Rural Change

Date published: 13 August 2020

Last updated: 25 April 2024

Annual estimates of the Northern Ireland resident population are produced by the Northern Ireland Statistics and Research Agency (NISRA). 

As the estimates refer to the number of people in the population at 30 June each year, they are referred to as the ‘mid-year’ estimates.  They are updated using a standard technique known as the cohort component method.  To show change over time, the previous year’s population estimate is ‘aged on’ by one year, with births added, deaths removed, and net migration accounted for.  The mid-year estimates are calculated using the 2011 NI Census of Population as a base.
