The Office for National Statistics (ONS) is responsible for the Census in England & Wales. The Census has been carried out every 10 years since 1801, except in 1941. Find out more about the background to the Census here....
The latest Census took place on 27th March 2011.
The Census is the most comprehensive source of information about the country's population. It is a survey that covers everyone at the same time asking the same questions everywhere, making it easy to compare different parts of the country. It is a legal requirement that everyone be included in the Census.
It covers millions of households as well as communal establishments, for example care homes. It even includes British Citizens abroad on temporary postings with the armed forces, people sleeping rough and visitors.
Census information is also vital in helping us plan and deliver local services based on customer need.
To see more information about how the survey was conducted, the reliability of the results and glossary please visit the Office for National Statistics.
Please Note : This area of our website is revised as more data from the 2011 Census becomes available.
