Industrial classification codes (NAICS & SIC) are used to classify and measure industry activity. Knowing the code for your industry will help you find articles, reports and other information about an industry.
Adopted in 1997,the North American Industry Classification System (NAICS) is the standard used by Federal statistical agencies in classifying business establishments for the purpose of collecting, analyzing, and publishing statistical data related to the U.S. business economy.
Adopted during the 1930's, the Standard Industrial Classification System updates ended in 1987. Although many older industries still use the SIC codes, newer industries are better defined using the NAICS.
