The federal government has recently unveiled the North American Industry Classification System (NAICS), which will provide common industry definitions for Canada, Mexico, and the US. NAICS replaces the older Standard Industrial Classification System (SIC) in the US, where implementation of NAICS will begin this year with the Census Bureau's 1997 Economic Census. This site provides the NAICS implementation time schedule, NAICS and SIC comparability tables, and a number of issue papers and concept reports relating to the new system. Most of these documents are offered in either PDF or ASCII formats. While the site is probably most useful to specialists, it does provide a thorough overview of this new structure for comparing economic and financial statistics of the NAFTA partners.
