This dataset provides 2011 estimates that classify households in England and Wales by four dimensions of deprivation: Employment, Education, Health and disability, and Household overcrowding. The estimates are as at census day, 27 March 2011.

A household is classified as being deprived in none, or one to four of these dimensions in any combination.

Similar estimates from the 2001 Census were provided in table UV67 however there have been some minor changes to the definition of these dimensions, including the removal of the age restriction on employment.

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.
