This dataset provides 2011 Census estimates that classify usual residents aged 16 and over in employment the week before the census in England and Wales by industry, by ethnic group and by sex. The estimates are as at census day, 27 March 2011.

This information is used to assign a code to the industry an individual works in using the UK Standard Industrial Classification of Economic Activities (UKSIC). This enhances the quality of occupation coding and is required at a local level to understand economic performance and analyse local labour markets. It also provides information for policy development and monitoring land use, transport and housing needs.

This information is used to plan services and target resources, and allows public authorities to assess and tackle discrimination.

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.
