The North American Industry Classification System (NAICS) is the standard used by Federal statistical agencies in classifying business establishments for the purpose of collecting, analyzing, and publishing statistical data related to the U.S. business economy. It is a joint work between the Untied States, Canada, and Mexico that allows a high level of comparability between the countries. The NAICS officially replaced the SIC (Standard Industrial Classification) system in 1997. The publisher has included the SBA Size Standards Table as an appendix at the back of this book to assist users of the data.
