North American Industry Classification System (NAICS)

What is NAICS?
NAICS is the product of a cooperative effort on the part of the statistical agencies of the United States, Canada, and Mexico. Employers with similar production processes are classified in the same industry. NAICS focuses on how products and services are created, as opposed to SIC which focuses on what is produced. Using NAICS yields significantly different industry groupings than those produced using SIC. Due to these differences in NAICS and SIC structures, NAICS data will not be directly comparable to the SIC based data for earlier years.
