Data notes

Overview

• Summary of dataset and variables:

  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.

  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 for Scotland.

  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. Scotland published rebased 2012 to 2020 data on 9 July 2024.

  On 15 July 2024 estimates for mid-2022 were revised by the ONS to account for updated estimates of international migration for Wales and England.

  On 30 July 2025 estimates for mid-2022 and mid-2023 were revised by the ONS to account for updated estimates of international migration for Wales and England.

  Internal migration estimates for mid-2023 have been produced using a different method to previous years, following a change to the variables available in the Higher Education Statistics Agency data.
