We'll make a range of supporting information available to facilitate the use of Census 2021 data outputs in England and Wales.

This information will provide additional context to the data, for example, by outlining the questions included, definitions of key terms, quality measures and statistical methods.

We're still developing the content and are planning further work with users to ensure the supporting information can be used alongside census data effectively. We'll keep you updated on our progress here.

What we've done for Census 2021

We've been working with users to develop supporting information that meet user's needs, including how best to present supporting information through the flexible dissemination system.

We'll continue to update on our plans going forward.

More information
