Census 2021

What is the census?

On 21 March 2021, the 2021 United Kingdom census, called Census 2021, will occur throughout most of the United Kingdom. It will be administered by the Office of National Statistics (ONS) in England and Wales, by the Northern Ireland Statistics and Research Agency in Northern Ireland, and by the National Records of Scotland in Scotland. Census 2021 will be the first British census to collect most data online, and the ONS has confirmed that the census will go ahead despite the COVID-19 pandemic, in part because the information obtained will assist government and public understanding of the pandemic’s impact.
