Data reference periods

Data are produced and reported annually and relate to the 30 June of each year for a number of the Census years from 1871 and for each year from 2001 onwards.

Users, uses and context

The data presented here are used to understand the changing age structure of the Welsh population over the short and longer term. Since 2001, data are included for Welsh local authorities as well as Wales allowing short term change in age structure to be analysed for each local authority.

Rounding applied

Data are rounded to the nearest 0.1 of a percentage point and as a result may not total 100% when added over all age groups. The unrounded data behind the estimates for 2001 onwards can be found in the estimates folder in the same part of the StatsWales catalogue.

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 the 2011 Census (see weblinks).

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

To help with analysis of the impacts of the coronavirus pandemic on the UK population, the ONS has published a provisional set of population estimates for mid-2019. This report is by necessity a subset of the information they regularly publish in June, focusing primarily on the size, age structure and geography of the UK population.

Information of the components (drivers) of population change in each local area will be published in June. Any changes to the population estimates between now and June are likely to be minor, but it is possible that the estimates released in June 2020 will differ slightly from those published here.
