About the census

The census is a national survey that takes place every 10 years to count households and population in England and Wales. The last census day was on 21 March 2021.

The Office for National Statistics (ONS) organises the census in partnership with local authorities, including South Gloucestershire Council.

Why census data is collected

Information from the census will help decide how services are planned and funded in your local area. This could mean things like doctors’ surgeries, housing, and new bus routes.

Information from the census is also important in helping lots of other people and organisations do their work, including:

  • charities and voluntary organisations using it as evidence to get funding
  • helping businesses to understand their customers (for example, decide where to open new shops)
  • researchers (for example, university students and people looking into their family history)

It provides data on population diversity. This allows organisations to know whether they are meeting their responsibilities and taking action where necessary.
