As the demand increases for statistics and data to measure the impact of the COVID-19 pandemic, we have had to change our data gathering and release practices, focussing efforts on priority analysis and statistics.

Frequency of publication


Data reference periods

Data are produced and reported annually and relate to the 30 June of each year from 1991 onwards.

Users, uses and context

The data presented here are used by central government departments and local authorities 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 2001 to 2010 in re-basing the data to be consistent with the results of the 2011 Census (see weblinks).

This data set was revised on 3 May 2016 to correct an error of the age distribution in the council areas of Scotland.

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.
