This dataset provides 2011 Census estimates that classify the workday population aged 16 to 74 in England and Wales by industry. The estimates are as at census day, 27 March 2011.

The industry classification used is based on the UK Standard Industrial Classification of Economic Activities (UKSIC). This is used to enhance 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.

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.
