This dataset provides 2011 estimates that classify household spaces in England and Wales as those with none, and those with at least one usual resident. The estimates are as at census day, 27 March 2011.

This information is used to help central and local government assess changes in overcrowding. It provides data to help identify households in unsuitable accommodation, to tackle deprivation, develop appropriate housing policies, plan future housing provision and allocate resources.

Similar estimates from the 2001 Census were provided in table UV53.

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.

More details on the ONS Census disclosure control strategy may be found on the Statistical Disclosure Control page on the ONS web site.
