The 2021 census will take place on Sunday 21 March 2021. The census is a survey that happens every 10 years and gives us a picture of all the people and households in England and Wales. It's a unique source of information for all kinds of organisations, including local government, charities, and businesses.
Census-based local authority estimates will be available in March 2022.
The final outputs from the census are predicted to be available in March 2023.
Further information about the census is available on the Census 2021 website.
Why does the census matter?
Like all local authorities in England and Wales, we rely on census population statistics to identify local needs for public services. Central government funding relates to how many and what kind of people the census shows live in our area.
It needs to include everyone, everywhere, that's why everyone was asked to take part.
We have worked closely with our local partners and colleagues from the ONS to make sure a high response rate was secured for the 2011 Census in Slough. We have also been proactive and provided further data on the town’s population for use by the ONS as they quality assure the final census results for the area.
Census information can be mapped in 'output areas', which typically contain around 309 people. This is small enough that the council and other bodies can identify, for example:
- locations with a high proportion of children
- areas of high unemployment
- or areas with high or low house ownership.
