    "[b]Description of Data[/b]\r\nMid-2021 to mid-2024 population estimates for Parliamentary Constituencies and Health and Social Care Trusts in Northern Ireland were published on 11th December 2025.\r\n\r\n[b]Time Period[/b]\r\nEstimates are provided for mid-2021 to mid-2024.\r\n\r\n[b]Notes:[/b]\r\n1. The mid-year population estimates are generally quoted in rounded form, this is because population counts\r\nfrom the census and subsequent updates involving births, deaths and migration cannot be precise.\r\n2. In general the precision of the population estimates could be considered to be no better than to the nearest 100.\r\n\r\n[b]Methodology[/b]\r\nThe population estimates for small geographical areas are created from an average of two statistical methods: \r\nthe ratio change and cohort-component methods. The ratio change method applies the change in secondary (typically administrative) data sources to Census estimates. The 2024 small geographical area estimates use a single statistical dataset which has been created by amalgamating a series of different administrative data sources. This statistical dataset is a de-duplicated admin based estimate for the usually resident population of NI. The cohort-component method updates the Census estimates by ‘ageing on’ populations and applying information on births, deaths and migration. An average of both methods is taken and constrained to the published population figures. Further information is available at:\r\n[url=https://www.nisra.gov.uk/publications/2024-mid-year-population-estimates-northern-ireland-and-estimates-population-aged-85]NISRA 2024 Mid-year Population Estimates webpage[/url]\r\n\r\n[b]Geographic Referencing[/b]\r\nPopulation Estimates are based on a large number of secondary datasets. 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. \r\n\r\n[b]Further Information[/b]\r\nThe next estimates of the population for Northern Ireland will be released later in 2026.\r\n\r\nContact: Census Customer Services\r\n02890 255156\r\n[url=mailto:census@nisra.gov.uk]census@nisra.gov.uk[/url] \r\nResponsible Statistician: Catherine O'Donnell"
