The mid-year estimates refer to the population on 30 June of the reference year and are published annually.

They are the official set of population estimates for the UK and its constituent countries, the regions and counties of England, and local authorities and their equivalents.

This headline is based on the mid-2017 population estimates for England and Wales published by the Office for National Statistics (ONS).

The ONS published revised mid-2012 to mid-2016 estimates of the population on 22 March 2018 due to methodological improvements. The revised figures included new estimates of local authority international emigration and foreign armed forces dependants.
