The North American Industry Classification System (NAICS, pronounced Nakes) was developed as the standard for use by Federal statistical agencies in classifying business establishments for the collection, analysis, and publication of statistical data related to the business economy of the U.S. NAICS was developed under the auspices of the Office of Management and Budget (OMB), and adopted in 1997 to replace the old Standard Industrial Classification (SIC) system. It was also developed in cooperation with the statistical agencies of Canada and Mexico to establish a 3-country standard that allows for a high level of comparability in business statistics among the three countries. NAICS is the first economic classification system to be constructed based on a single economic concept.

The SIC covers the entire field of economic activities by defining industries in accordance with the composition and structure of the economy. Over the years, it was revised periodically to reflect the economy's changing industry composition and organization. The Office of Management and Budget (OMB) last updated the SIC in 1987.
