2011 census

Every 10 years the Office for National Statistics (ONS) carries out a census to find out more about the people who live in England and Wales and about the make-up of local neighbourhoods.

The 2011 census asked about work, health, national identity, citizenship, ethnic background, education, second homes, language, religion, marital status and more.

The statistics from the responses are used to build a picture of today's society.

Results and comparison to 2001 census

The results showed that the usually resident population for Cambridge in 2011 was 123,900 - an increase of about 15,000 (13%) from the results of the 2001 census.

The number of households in Cambridge had increased by 4,042 (9.5%) since 2001, and the population continued to show a 'bulge' in the number of people between 16 to 24 and 25 to 39 years of age, reflecting the large number of students resident in the city.

Overall, the population of Cambridge had aged slightly, although the increase in the number of older people, as a proportion of the population, still wasn't as high as in other areas.
