This dataset provides 2011 Census estimates that classify usual residents aged 16 and over in England and Wales by NS-SeC, by economic activity and by sex. The estimates are as at census day, 27 March 2011.

These statistics are used to help in developing and monitoring policy aimed at assessing the needs of population according to their socio-economic status. This information is used to plan services and target resources, and allows public authorities to assess and tackle discrimination.

Information on economic activity status - as defined by the International Labour Organisation - is used by central and local government, researchers and other organisations to understand local labour markets and to develop and monitor policies at local and regional levels. It is used to identify deprived areas, to allocate community and economic development funding, and for housing and transport planning purposes.

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.
