This estimate is provisional, and is based on published estimates for births, deaths and international migration.

Nôl i'r tabl cynnwys Our provisional UK population estimate has been calculated using published data, including: our UK population estimate for mid-2024 (69,281,000 people) our provisional estimates of long-term international migration for year ending (YE) June 2025 birth registrations for YE 30 June 2025, with provisional data from 1 January to 30 June 2025 death registrations for YE 30 June 2025 Our provisional mid-2025 population estimate provides a timelier and more accurate estimate than is available from population projections for mid-2025. It can be used when an up-to-date estimate is needed for per capita indicators, such as gross domestic product (GDP) per head. However, it should not be used for comparisons with estimates for smaller geographic areas in previous years. Subnational survey weights should continue to use the existing subnational population estimates and projections. We aim to publish mid-2025 population estimates in summer 2026. These will include: international migration estimates updated with the latest and most complete data official estimates of international migration for Northern Ireland adjustments to the number of deaths, by date of occurrence, to account for late registrations more complete data on births; the birth estimates used in this release are based on provisional data from 1 January to 30 June 2025 changes in the number of home and foreign armed forces personnel for YE 30 June 2025 revisions to mid-year estimates for mid-2022 to mid-2024 reflecting the latest long-term international estimates.
