• A follow up evaluation survey will be taking place in some areas and we may invite you to give us your views on the test through a short interview.

We would like to thank the people in all our test areas for your invaluable assistance. Testing is an important part of our preparations for the next census. We understand that modern life places many demands on us all, and we do not take your contribution lightly. We are grateful for your time and your help, and for the kindness shown to our field staff. We’ve learned valuable lessons which will help us to hold a better census in 2021.

With kind regards from the 2017 Census Test teams.

About the census

A census has been held in England and Wales every 10 years for over 200 years (except in 1941). It gathers information about the population and housing so that central and local government can plan and fund public services. The next census in England and Wales will be in 2021.
