The population of England and Wales has increased by more than 3.5 million in the 10 years leading up to Census 2021. Using the first results from this census, we look at which places have seen the biggest increases and decreases, which areas had the largest growth in different age groups, and how local authority areas like North East Derbyshire compare with others.
The English region with the largest population increase was the East of England, which grew by around 8.3% or 488,000 more residents. The English region with the smallest increase was the North East, growing by 1.9% or around 50,000 people. In Wales, the population grew by 1.4% or 44,000 people.
