The conduct of the 2021 Censuses in the UK
- A statement of agreement between the National Statistician and the Registrars General for Scotland and Northern Ireland - October 2015
This is statement of agreement, similar to the one for the 2011 Census, between the National Statistician and the Registrars General for Scotland and Northern Ireland about the conduct of the 2021 Censuses.
The statement outlines a number of principles where the three census offices will work in unison to ensure the 2021 Censuses are a success in providing high-quality population and housing statistics for the UK, meeting the needs of data users and reflecting UN-ECE, Eurostat and other international requirements.
This statement ensures that the independent censuses carried out in each constituent country of the UK are able to provide consistent and high-quality statistics that meet user requirements for UK level data.
