Standard Industrial Classification

The Standard Industrial Classification (abbreviated SIC) is a system for classifying industries by a four-digit code. Established in the United States in 1937, it is used by government agencies to classify industry areas, e.g. by the UK's Companies House.

In the Unites States the SIC code is being supplanted by the six-digit North American Industry Classification System (NAICS code), which was released in 1997; however certain government departments and agencies, such as the U.S. Securities and Exchange Commission (SEC), still use the SIC codes.

The SIC codes can be grouped into progressively broader industry classifications: industry group, major group and division. The first 3 digits of the SIC code indicate the industry group, and the first 2 digits indicate the major group. Each division encompasses a range of SIC codes: for instance, the division of manufacturing holds all SIC codes with the first two digits between 20 and 39. To look at a particular example of the hierarchy, SIC code 2024 (ice cream and frozen desserts) belongs to industry group 202 (dairy products), which is part of major group 20 (food and kindred products), which belongs to the division of manufacturing.

The following table is from the SEC's site, which allows searching for companies by SIC code in its database of filings. The acronym NEC stands for "not elsewhere classified."

Famous quotes containing the words standard and/or industrial:

    When Freedom, from her mountain height,
    Unfurled her standard to the air,
    She tore the azure robe of night,
    And set the stars of glory there;
    Joseph Rodman Drake (1795–1820)

    If you do not regard feminism with an uplifting sense of the gloriousness of woman’s industrial destiny, or in the way, in short, that it is prescribed, by the rules of the political publicist, that you should, that will be interpreted by your opponents as an attack on woman.
    Wyndham Lewis (1882–1957)
