NEW INDUSTRY CLASSIFICATION SYSTEM: "NAICS" or
THE NORTH AMERICAN INDUSTRIAL CLASSIFICATION SYSTEM
For over sixty years, industry information has been compiled using the Standard Industrial Classification (SIC) system. The industry data tables produced for this website were classified by SIC. As of the industry data tables for the year 2001 and beyond the North American Industry Classification System (NAICS) will be used for industry related data.
Developed jointly by the United States, Canada and Mexico to produce comparable data among these nations, NAICS was introduced in 1997 to replace the SIC system. Because of its scope and complexity, the transition to NAICS has taken three years to complete and is now effective beginning with 2001 data. Most all federal data pertaining to business and industry will be provided using the new NAICS industry classifications. NAICS provides a more specific classification system reflecting the economy's changing industrial composition. NAICS focuses on how products and services are created, as opposed to the SIC focus on what is produced.
The reorganization of the industry classification system has created breaks in industrial time series data. To illustrate, in the case of manufacturing, even though the Manufacturing industry group is still listed, the current statistical data for Manufacturing may not be comparable to what was previously shown. For example, an industrial machine company has its employment offices in a separate building. Those workers may now be listed in the Professional and Business Services industry under NAICS, rather than in Manufacturing. The same is possible for other industries.
NAICS uses a six digit hierarchical coding system to classify all economic activity. NAICS-United States allows for the identification of 1,170 industries compared to the 1,004 found in the SIC system. NAICS classifications are reviewed every three years. For purposes of the industry pages produced for this website economic activities will be aggregated into 11 NAICS 'super sectors'.
NAICS 2002 is the same as NAICS 1997 for fourteen of the twenty sectors. Construction and wholesale trade are substantially changed, but the revisions also modify a number of retail classifications and the organization of the information sector. Very minor boundary adjustments affect administrative and support services and mining.
The following is a listing of the NAICS industry 'super sectors':
Natural Resources & Mining includes agriculture, forestry, fishing, hunting, and mining.
