UK Standard Industrial Classification 2007 (UK SIC 2007)

A Standard Industrial Classification (SIC) was first introduced into the UK in 1948 for use in classifying business establishments and other statistical units by the type of economic activity in which they are engaged.

The classification provides a framework for the collection, tabulation, presentation and analysis of data, and its use promotes uniformity.

In addition, it can be used for administrative purposes and by non-government bodies as a convenient way of classifying industrial activities into a common structure.

Since 1948 the classification has been revised in 1958, 1968, 1980, 1992, 1997, and 2003.
