* NAICS, the North American Industry Classification System, is The North American Industry Classification System (NAICS) represents a continuing cooperative effort among Statistics Canada, Mexico's Instituto Nacional de Estadística y Geograa (INEGI), and the Economic Classification Policy Committee (ECPC) of the United States, acting on behalf of the Office of Management and Budget, to create and maintain a common industry classification system.

With its inception in 1997, NAICS replaced the existing classification of each country—the Standard Industrial Classification (1980) of Canada, the Mexican Classification of Activities and Products (1994), and the Standard Industrial Classification or SIC Codes (1987) of the United States.

Since 1997, the countries have collaborated in producing five-year revisions to NAICS in order to keep the classification system current with changes in economic activities
