This table provides information that classifies households by the combination of adults and children within a household that have English (English or Welsh in Wales) as a main language, for England and Wales as at census day, 27 March 2011. The definitions of adult (aged 16 and over) and child (aged under 16) used in this table are the non-standard versions. These are used in a small number of census results. For more information refer to 2011 Census glossary.

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.
