Press releases : First Census 2021 results show continued population growth in England and Wales

The usual resident population of England and Wales was 59,597,300 on Census Day, 21 March 2021.

This was the largest population ever recorded through a census in England and Wales – an increase of more than 3.5 million (6.3%) compared with Census Day 2011.

The population is also ageing, with 18.6% of people aged 65 and over, up from 16.4% a decade earlier.

There were 56,489,800 people in England and 3,107,500 people in Wales. In England, the population grew by almost 3.5 million (6.6%) from the 2011 Census population estimate of 53,012,456 people. The rate of growth was considerably lower in Wales, where the population grew by 44,000 (1.4%) from the 2011 Census population estimate of 3,063,456 people.

Commenting on the numbers, the Office for National Statistics’ Deputy National Statistician Pete Benton said: “Today’s census statistics begin to paint a rich and detailed snapshot of the nation and how we were living during the pandemic. They show the population of England and Wales continued to grow across the decade, albeit at different rates across the regions.

“Ultimately, the full suite of census results, based on the information we all gave, will ensure decisions about how the billions of pounds we spend each year as a nation are made using the best possible evidence. This includes planning our emergency services, mental health care, school places, hospital beds, houses, roads, buses, trains, trams, GPs and dentists’ services.”

Pete added: “Since Census Day the world has continued to change. People continue to move home, some people will have left the country, others will have arrived. People will have changed jobs, some of us now work in offices once again, while others continue to work from home.

“We need to understand all of this and more. The results from Census 2021 – and there’s lots more to follow - therefore provide a key bridge from the past to the future as we deliver more frequent, relevant and timely statistics using data from across government to allow us to understand population change in local areas this year and beyond.”

The first Census 2021 estimates show the region with the highest population growth was the East of England, which increased by 8.3% from 2011 (a gain of approximately 488,000 people). The South West and London were the areas with the next highest rates of population growth.

Note to editors:

  • We’ve created an interactive population game where you can guess whether the number of people living in an area is higher or lower than a neighbouring area. The embeddable code is available here
  • In July we will explain how we are transforming our population and migration statistics beyond a traditional census. We will publish a proof of concept for producing ‘admin-based’ population estimates using information from health, tax, benefits and education data sources, among others. We will also publish a statistical design for admin-based migration estimates.
