2011 Census

The census has been taken every ten years since 1801 (with the exception of 1941). It forms the most comprehensive data set on the population and its characteristics and is used to inform policy and spending decisions, identify community needs and shape local priorities.

The most recent census was undertaken by the Office for National Statistics on 27th March 2011.

The next census in England and Wales will be in 2021.
