Mid-year population estimates - Northern Ireland

<b>Description of Data</b> Notes: 1. The estimates are produced using a variety of data sources and statistical models. Therefore small estimates should not be taken to refer to particular individuals. 2. The migration element of the components of change have been largely derived from a data source which is known to be deficient in recording young adult males and outflows from Northern Ireland. Therefore the estimates are subject to adjustment to account for this and, while deemed acceptable for their use, will not provide definitive numbers of the population in the reported groups/areas. Further information is available in the Limitations section of the statistical bulletin: [NISRA 2024 Mid-year Population Estimates webpage](https://www.nisra.gov.uk/publications/2024-mid-year-population-estimates-northern-ireland) <b>Time Period</b> Estimates are provided for mid-1971 to mid-2024. <b>Methodology</b> The cohort-component method was used to create the population estimates for 2024. This method updates the Census estimates by 'ageing on' populations and applying information on births, deaths and migration.

Where the full address was available, the Pointer Address database was used to allocate a unique property reference number (UPRN) and geo-spatial co-ordinates to each home address. These can then be used to map the address to particular geographies. Where it was not possible to assign a unique property reference number to an address using the Pointer database, or where the secondary dataset contained only postcode information, the Central Postcode Directory was used to map home address postcodes to higher geographies. A small proportion of records with unknown geography were apportioned based on the spatial characteristics of known records. <b>Further Information</b> [NISRA Mid-year Population Estimates webpage](https://www.nisra.gov.uk/statistics/population/mid-year-population-estimates) Contact: NISRA Customer Services 02890 255156 [census@nisra.gov.uk](mailto:census@nisra.gov.uk) Responsible Statistician: Shauna Dunlop
