What is the census?

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. The census asks questions about people, their household and their home. The census will give us the most accurate, up to date snapshot of Merton and the needs of our residents.

The Office for National Statistics (ONS) is responsible for delivering the census in England and Wales.

The 2021 Census was the first 'digital-first' census with most people filling the census out online. Census Day was Sunday 21 March 2021. 

Why the Census matters

Like all local authorities London Borough of Merton relies on census population statistics to get the government funding we need for public services. How much we get is directly related to how many and what kind of people the census says live in our area. This is also true for health services, policing, public transport and other local public services. So, the census figures make a very real difference to people’s lives and we would like to thank everyone who took the time to take part.
