AutoNAICS 2.1

AutoNAICS is an electronic version of the 2002 North American Industry Classification System Manual.
The United States, Canada and Mexico created a common industrial classification system to facilitate economic analyses of the three North American countries. The result, the North American Industry Classification System (NAICS), replaces the former industrial classification systems of the three countries. A complete discussion of the NAICS system can be found at the U.S. Bureau of Census's North American Industry Classification System.
