NAICS

The North American Industry Classification System (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.

The Gross Domestic Product (GDP) by state estimates currently use the 1997 NAICS.

The state and local area personal income, earnings, and employment estimates currently use the 2002 NAICS.

For descriptions of NAICS industries, please see http://www.census.gov/epcd/www/naics.html at the Census Bureau.
