General description

This dataset provides population estimates for the local authorities in Wales, the English regions and the UK countries for the period from 1991 onwards by sex and single year of age, together with some aggregated age groups.

It should be noted that for mid-2020 there are some definitional changes (particularly affecting the migration components) compared with mid-2019 population estimates data and it is advised users read the Quality and Methodology Information section on the Office for National Statistics website.

For Wales, England, and Northern Ireland, the mid-2021 population estimates are the first population estimates to be based on the 2021 censuses for these countries. For Scotland, the census was moved to 2022, the mid-2022 population estimates are the first population estimates to be based on the 2022 census

Users, uses and context

The data presented here are used by central government departments and local authorities for a range of purposes including planning and monitoring of services and as denominators for the calculation of various rates and indicators.

Rounding applied

Data are provided on an unrounded basis although the Office for National Statistics advises that any results presented from these data are rounded to the nearest 100 where practical.

Revisions information

The data presented here reflect changes made to population estimates from 2001 to 2010 in re-basing the data to be consistent with the results of Census 2011 (see weblinks).

The data for Scotland from 2001 to 2010 were revised on 18 March 2022 to correct an error in the age distribution over this period (see weblinks).

This data set was revised for 2012 to 2014 on 3 May 2016 to correct an error of the age distribution in the council areas of Scotland.

Mid-2012 to mid-2016 subnational population estimates for Wales and England were revised on the 22 March 2018, following methodological improvements (see weblinks).

On 23 November 2023, the data set from 2012 to 2020 for Wales and England were rebased to be consistent with the results of Census 2021. Northern Ireland published rebased 2012 to 2020 data on 29 June 2023. Data for Scotland is due to be rebased in the second half of 2024.
