This dataset provides 2011 estimates that classify households in United Kingdom by occupancy rating based on the number of rooms in the household. The estimates are as at census day, 27 March 2011.

This information is used to provide a measure of under-occupancy and over-crowding to allow central and local government to develop appropriate housing policies and plan future housing provision.

In Northern Ireland this table is numbered QS407NI.

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.
