About the census : The Census Coverage Survey

The Census Coverage Survey (CCS) was a short, separate survey that we at the Office for National Statistics (ONS) started six to eight weeks after Census Day.

The CCS helps make sure everyone is counted and our census results are as accurate as possible. It asked similar questions to the main census, just fewer of them, at addresses in a selection of postcodes across England and Wales.

The CCS has now closed.

What to do if you were invited to take part

If we left you a paper questionnaire, you will no longer need to complete it.

You needed to return your completed questionnaire by Saturday 26 June 2021.

Any questionnaires we receive after this date will not be counted.
