"Industry classification or industry taxonomy organizes companies into industrial groupings based on similar production processes, similar products, or similar behavior in financial markets. A wide variety of taxonomies is in use, sponsored by different organizations and based on different criteria."
Industry Classification Systems
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. NAICS was developed under the auspices of the Office of Management and Budget (OMB), and adopted in 1997 to replace the Standard Industrial Classification (SIC) system. It was developed jointly by the U.S. Economic Classification Policy Committee (ECPC), Statistics Canada , and Mexico's Instituto Nacional de Estadistica y Geografia , to allow for a high level of comparability in business statistics among the North American countries. This site provides the latest information on plans for NAICS revisions, as well as access to various NAICS reference files and tools. The official 2012 U.S. NAICS Manual includes definitions for each industry, background information, tables showing changes between 2007 and 2012, and a comprehensive index.

Published only once every five years, the North American Industry Classification System (NAICS) is an indispensable volume of official industry codes used by businesses, libraries, and other establishments and individuals to complete tax returns, grant requests, and fill out other forms and to improve analyses and comparisons of different industries. NAICS officially replaced the U.S. Standard Industrial Classification (SIC) system in 1997. It provides a consistent system of economic analysis across the three NAFTA nations—Canada, Mexico, and the United States. NAICS is used by U.S. statistical agencies to facilitate the collection, tabulation, presentation, and dissemination of data relating to establishments and to provide uniformity and comparability in the presentation of statistical data describing the U.S. economy. These statistics are used by all kinds of businesses, government agencies, policy analysts, academics and researchers, and the general public. NAICS is a comprehensive system covering all economic activities. The 2012 edition of NAICS supersedes the 2007 edition published in May 2007. The 2012 edition includes new and emerging industries, several title changes, and clarification of industry definitions.
Note: In the United States the SIC code is being supplanted by the six-digit North American Industry Classification System (NAICS code), which was released in 1997; however certain government departments and agencies, such as the U.S. Securities and Exchange Commission (SEC), still use the SIC codes.
