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.

The mid-2020 population estimates are the first population estimates to show some of the impacts of the coronavirus (COVID-19) pandemic. However, these estimates refer to the population as at 30 June 2020, meaning that they only account for the first three months of the pandemic.
Future releases of the population estimates will provide information on the impact from mid-2020 onwards.
It should be noted that for mid-202 there are some definitional changes (particularly affecting the migration components) compared to mid-2019 populations estimates data and it is advised users read the Quality and Methodology Information section on the Office for National Statistics website.

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).
