This dataset provides 2011 estimates that classify household spaces with at least one usual resident in England and Wales by the number of rooms. The estimates are as at census day, 27 March 2011.

It provides data to help identify households in overcrowded or unsuitable accommodation. This information is used by central and local government to tackle deprivation, develop appropriate housing policies and plan future housing provision.

Similar estimates from the 2001 Census were provided in table UV57 however the maximum number of rooms category has increased from eight rooms or more, to nine rooms or more.

In order to protect against disclosure of personal information from the 2011 Census, there has been swapping of records in the Census database between different geographic areas, and so some counts will be affected. In the main, the greatest effects will be at the lowest geographies, since the record swapping is targeted towards those households with unusual characteristics in small areas.
