About the census : About the Census Quality Survey
The Census Quality Survey (CQS) is a smaller survey we carry out after the census.
How it works
We ask a certain number of households in England and Wales to take part by answering some of the same questions from the census questionnaire.
What it’s for
The results of the CQS let us work out how accurate the information was that we collected in the census and improve our statistics.
Our census statistics help to plan and fund public services in your area.
