About the census : Overview
What is the census?
The census is a once-in-a-decade survey that gives us the most accurate estimate of all the people and households in England and Wales. The information you give helps decide how services are planned and funded in your local area. This could mean things like doctors’ surgeries, housing or new bus routes.
It asks questions about you and your household to build a picture of all of us. It looks at who we are and how we live. There’s no other survey that gives as much information about our society and future needs.
Past, present and future
The census takes place every 10 years. The first census was in 1801 and the most recent in 2011. The next census is planned for 2021. The Office for National Statistics (ONS) delivers the census. We need every household in England and Wales to take part to make it accurate.
We also need your help between each census. At the ONS, we rely on ongoing studies to provide detailed, up-to-date information about changes to society. To ensure that we represent everyone, we ask selected individuals to take part in these studies. Some are carried out face-to-face, some over the phone and some online.
These studies do not stop while the Census takes place. To find out more about the types of studies we run throughout the year, visit the ONS website.
