General description

This dataset provides population estimates for the local health boards in Wales, for the period from 2009 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 populations estimates data and it is advised users read the Quality and Methodology Information section on the Office for National Statistics website.

For Wales, the mid-2021 population estimates are the first population estimates to be based on Census 2021.

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 (HESA) data.

Users, uses and context

The data presented here are used by central government departments, local authorities and local health boards 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 2009 to 2010 in re-basing the data to be consistent with the results of Census 2011 (see weblinks).

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

From 1 April 2019, health service provision for residents of Bridgend local authority moved from Abertawe Bro Morgannwg to Cwm Taf. For more information see the joint statement from Cwm Taf and Abertawe Bro Morgannwg University Health Boards (see weblinks). The health board names have changed with Cwm Taf University Health Board becoming Cwm Taf Morgannwg University Health Board and Abertawe Bro Morgannwg University Health Board becoming Swansea Bay University Health Board. A link to the statement from the Minister for Health and Social Services can be found in the weblinks section.

On 23 November 2023, the data set from 2012 to 2020 for Wales and England was rebased to be consistent with the results of Census 2021.

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