North American Industry Classification System (NAICS)
Mining, Quarrying, and Oil and Gas Extraction - Utilities - Construction
The NAICS has replaced the U.S. Standard Industrial Classification (SIC) system. NAICS was developed jointly by the U.S., Canada, and Mexico to provide new comparability in statistics about business activity across North America. For the first time, government and business analysts will be able to compare directly industrial production statistics collected and published in the three North American Free Trade Agreement countries.
