Statistics and census information

Wandsworth’s resident population is 329,735 (Office for National Statistics mid-2020 estimate).

Annual estimates and projections of the population of the borough and its wards are produced by the Office for National Statistics and the Greater London Authority.

The Census and population projections based on it provide important statistics about the population so that public services like schools, community centres, health facilities and emergency services can be planned around people's needs.

Census scams

We are keen to protect the public from census scams that are still operating. These scam texts threaten the recipient with a £1000 fine for not completing the census, or for filling it in incorrectly.

Be aware:

  • The ONS will never contact someone by text in relation to the census
  • The ONS will never issue a fine by text, phone call, email or social media

Scam text messages can be forwarded to 7726 and scam emails to report@phishing.gov.uk

Read further information on the census website about your data and security.
