Census 2021

Explore the changes in Oxfordshire’s population from the Census carried out on 21 March 2021.

The census takes place every ten years. It is a detailed snapshot of all the people and households in England and Wales. Information from the census helps us plan and fund local services, such as education and roads.

One in six people in England and Wales were born outside of the UK and that figure is slightly higher in Oxfordshire at 18.7 per cent or just over one in five.
