Standard Industrial Classification (SIC) System

The Standard Industrial Classification has been replaced by the new North American Industry Classification System (NAICS), but several data sets are still available with SIC-based data. Both SIC and NAICS classify establishments by their primary type of activity.

Data available on this site by SIC:

• 1997 Economic Census: (including establishments, sales or other measure of output, employment and payroll):
  • Comparative Statistics (1992 and 1997 data by 4-digit SIC for the U.S. and states)
  • Bridge Between NAICS and SIC (a key to the comparability of the two classification systems for particular industries, national data only)
  • Minority- and Women-Owned Business (2-digit SIC for all firms as well as for employers, for the U.S. and states, with sector totals for metro areas)
  • Business Expenses (national data for selected sectors only)

• 1992 Economic Census data for the U.S., states, counties, cities, and metro areas in pdf and on CD-ROM,
  

• County Business Patterns, 1993 to 1997, including counts of establishments by employment size class, employment, and payroll, but no measures of output.

• Other economic programs, most of which discontinued SIC-based reporting between 1997 and 2001.

Lookup system to find the SIC code for keywords that you enter (transfers you to OSHA web site).

The NAICS web site includes correspondence tables and a discussion of How NAICS Will Affect Data Users.
