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 Mid Suffolk 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.

In Mid Suffolk, the population size has increased by 6.2%, from around 96,700 in 2011 to 102,700 in 2021. This is lower than the overall increase for England (6.6%), where the population grew by nearly 3.5 million to 56,489,800.
A map of local authority areas in England is coloured to indicate the percentage change in population of each area. The data used in this article are available to download at the end.
Nearby areas like South Norfolk and Breckland have seen their populations increase by around 14.4% and 8.4%, respectively, while others such as Ipswich saw an increase of 4.7% and East Suffolk saw smaller growth (2.6%).
The map then zooms to centre on Mid Suffolk and show neighbouring areas.
At the other end of the scale, North Norfolk has seen an increase of just 1.5%.
The local authority areas displayed on the map change form and position to create a bar chart that orders selected areas of the East of England by percentage change in total population.
At 6.2%, Mid Suffolk's population increase is lower than the increase for the East of England (8.3%).
Mid Suffolk is highlighted on the bar chart along with other local authority areas in the East of England.
Tower Hamlets saw the largest percentage growth in population in England, increasing 22.1% between 2011 and 2021. Dartford was second, increasing 20.0%.
Every local authority area of England is shown as a dot on a chart, with the legend running from the largest percentage decrease to the highest percentage increase in population. Mid Suffolk is highlighted.
Some local authority areas have seen their populations decline. Kensington and Chelsea had an estimated population of 143,400 in 2021, which was around 15,200 fewer than in 2011 and a decrease of 9.6%.
The chart continues to show all areas of England as dots, ordered by the percentage change in total population, with the largest decreases towards the left and the largest increases towards the right.
The total population of local authority areas varies a lot, from Birmingham with around 1,144,900 people to the Isles of Scilly with around 2,100 people. The sizes of these circles are proportionate to the size of the population in each local authority area.
The chart changes into circles located at the centre of each local authority area on a map. The area of each circle indicates the total population.
As of 2021, Mid Suffolk is the fourth least densely populated of the East of England's 45 local authority areas, with an area equivalent to around one football pitch per resident.

Population change in certain areas may reflect how the coronavirus
(COVID-19) pandemic affected people's choice of usual residence on Census
Day, for example, students and in some urban areas.
These changes might have been temporary for some and more long-lasting for others.
