Office for National Statistics’ (ONS) Administrative Data Census Project was set up to assess whether the government’s stated ambition that “censuses after 2021 be conducted using other sources of data” can be realised.

Ambition to meet users’ needs

We’re aiming to replicate the type of information collected through a census by using the administrative data already held by government, supplemented by surveys. Our goal is to compare statistical outputs based on administrative data and surveys with 2021 Census data, to show that this alternative can meet users’ needs with high-quality information at a lower cost, and more frequently.
