Introduction to NAICS
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.
NAICS was developed under the auspices of the Office of Management and Budget (OMB), and adopted in 1997 to replace theStandard Industrial Classification (SIC) system. It was developed jointly by theU.S. Economic Classification Policy Committee (ECPC),Statistics Canada, and Mexico'sInstituto Nacional de Estadistica y Geografia, to allow for a high level of comparability in business statistics among the North American countries.
This official U.S. Government Web site provides the latest information on plans for NAICS revisions, as well as access to various NAICS reference files and tools. Additional information on the background and development of NAICS is available in the section of this Web site.
