Beginning in 1997, the Standard Industrial Classification (SIC) was replaced by the North American Industry Classification System (NAICS). This six digit code is a major revision that not only provides for newer industries, but also reorganizes the categories on a production/process-oriented basis. This new, uniform, industry-wide classification system has been designed as the index for statistical reporting of all economic activities of the U.S., Canada, and Mexico.*
