2021 Census 




The first results of the 2021 Census were published in June 2022 and show information at Local Authority level, so we are able to identify major data that relates to the Borough of Colchester. At a later stage, we will be able to analyse this, and more specific, data data by Parish. But here are the headlines:


The population of the Borough of Colchester has increased by 11.3% since the last census in 2011. The population of the Borough at that time was 173,074; it was 192,700 at the time of the latest census, and will have grown further in the last year.

The area encompassing the Borough of Colchester is far greater than the area covered by the Deanery, which covers around 56 square miles; the Borough covers 125 square miles. Therefore, care should be taken when using the these figures. However, making an assumption based on the last census, we would estimate the Deanery's population at 145,000 this time last year.




The overall population increase in England was 6.6% over the last decade. The East of England as a whole shows the highest percentage growth at 8.3%; Colchester's growth at 11.3% was the highest of the Local Authority areas which border us.


Of the 309 Local Authorities in England, Colchester is now in the 100 most highly populated (99th, up from 105 in 2021).


Here are the rankings for our local areas:

Density and dwellings

At the time of the census, population density was 587 people per Km2, the equivalent of four people living on each football-pitch piece of land. The average for Essex is 435; Chelmsford is, for instance, 536 and Tendring 440.

There are 79,700 dwellings within the Borough - showing an increase of around 5,100 in the last decade.

More about our population

Of the 192,700 people in the Borough in 2021, 98,500 (51.1%) were female and 94,200 male.

Numbers in each age group are reported as follows:

Or, in broader bands:

The number of children aged 0-4 has not changed significantly (up 1%) in the decade, whereas those of working age (say 20-64) at 112,900 shows an increase of 8.2%.The number of those 65 and over (34,300) is 25% greater than in 2021; however, it's a truism that anyone aged (say) 50 has personally aged 25% in the last decade!

This is the first release of statistics from the Census, and much more will follow in the months ahead. Every effort has been made to ensure that the facts, figures and summarisations are accurately and appropriately represented, but we apologise if any errors have been inadvertently made. We trust that the information will be found helpful for Parishes in their ministry to the people of Colchester.
