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 revised population estimates for England and Wales, mid-2012 to mid-2016 published by the Office for National Statistics (ONS). Methodological improvements have been implemented allowing the creation of a new series of estimates that roll forward the 2011 Census. These revised figures include new estimates of local authority international emigration and foreign armed forces dependants.

While regional, county and local authority-level estimates have changed, national-level estimates for both England and Wales have been held constant and so related national-level releases such as the 2016-based national population projections are unaffected.

Key points

  • On 30 June 2016 there were estimated to be 3,113,000 people living in Wales.
  • There were estimated to be more people aged 65 and over living in Wales (635,000) than children aged 0 to 15 (557,000).


As agreed with the Office for Statistics Regulation, these statistics will be updated at 12.30pm on the day of release by ONS. StatsWales tables will follow within 48 hours.
