Links Census 2021 Census 2021 - What's it all about? What the census is - Click here for different langauges All kinds of organisations, from local authorities to charities, use the information to help provide the services we all need, including transport, education and healthcare. Without the census, it would be much more difficult to do this. By taking part, you’ll be helping make sure you and your community get the services needed now and in the future. Past, present and future The first census was in 1801 and the most recent in 2011. The Office for National Statistics (ONS) runs the census in England Wales and the next one will happen on Sunday 21 March 2021. To prepare for it, we held a census rehearsal in 2019 to check our processes, systems and services were running smoothly ahead of the real thing. Between censuses We also need your help between each census. At the ONS, we rely on ongoing surveys to provide detailed, up-to-date information about changes to society. To make sure that we represent everyone, we ask people to take part in these surveys. We carry out interviews in person, by phone or online. These surveys do not stop while the census takes place.
