This table provides information that classified usual residents aged 16 and over by marital and civil partnership status, for United Kingdom as at census day, 27 March 2011.

This classification takes account of the Civil Partnership Act which came into force on 5 December 2005, providing information about civil partnership status for the first time in census results.

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.
