Louisville Business Research: Research an Industry

Industry Classification Codes

Every industry is given a classification code by the U.S. government. The two main classification systems are:

  • NAICS (North American Industry Classification System): 6-digits
  • SIC (Standard Industrial Classification): 4-digit

While some databases will allow you to search for the appropriate NAICS code, the government websites below can help you identify the correct NAICS and SIC codes for a particular industry. There may be multiple codes relevant to the industry you are researching.

Industry Profiles & Reports

Use these resources to find profiles and data about U.S. industries.  While a few profiles will be international, most will be national, and some may discuss regional strengths and weaknesses or provide regional data breaks.
