Coincident full censuses have taken place in the different jurisdictions of the United Kingdom every ten years since 1801, with the exceptions of 1941 (during the Second World War), Ireland in 1921/Northern Ireland in 1931,[1] and Scotland in 2021. In addition to providing detailed information about national demographics, the results of the census play an important part in the calculation of resource allocation to regional and local service providers by the UK government.
The most recent UK census took place in England, Wales and Northern Ireland on 21 March 2021.[2] Because of the COVID-19 pandemic, the census in Scotland was delayed to 20 March 2022.[3][4]
