About this dataset

The midyear (30 June) estimates of population are based on results from the latest Census of Population with allowance for under-enumeration. Available at Local Authority level and above.

Rebasing of population estimates: This dataset contains the population estimates for each country and local authority of the UK rebased to the results of the 2021/2022 censuses across the UK. These estimates replace previously published estimates for 2011 to 2022.

Usual residence definitions: the estimated resident population of an area includes all those people who usually live there, regardless of nationality. Arriving international migrants are included in the usually resident population if they remain in the UK for at least a year. Emigrants are excluded if they remain outside the UK for at least a year. This is consistent with the United Nations definition of a long-term migrant. Armed forces stationed outside of the UK are excluded. Students are taken to be usually resident at their term time address.

Rounding: estimates are presented unrounded. Unrounded estimates are published to enable and encourage further calculations and analysis. However, the estimates should not be taken to be accurate to the level of detail provided. More information on the accuracy of the estimates is available in the Quality and Methodology document.

Small counts: the estimates are produced using a variety of data sources and statistical models, including some statistical disclosure control methods, and small estimates should not be taken to refer to particular individuals.
