Rebased mid-2012 to mid-2020

The small area population estimates dataset was updated on 25 November 2024. Main points:

  • Estimates for mid-2012 to mid-2020 have been rebased to align with Census 2021 results.
  • Estimates for mid-2011 to mid-2022 are now available on the statistical geographies used for Census 2021.
  • Estimates for mid-2022 have been revised in line with changes to our mid-2022 local authority level estimates published in July 2024.

Datasets

The 2021-based small area population estimates dataset can be accessed under the Population Estimates source in Nomis queries:

The estimates in this release replace the old 2011-based small area poplation estimates. The dataset that contained the old estimates has been withdrawn.

Upcoming releases

ONS will publish small area estimates for mid-2023 for England and Wales after revisions are made to mid-2023 local authority estimates in summer 2025. This will be alongside a first release of mid-2024 local authority estimates.
