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. NAICS uses a production-oriented conceptual framework to group establishments into industries based on the activity in which they are primarily engaged. Establishments using similar raw material inputs, similar capital equipment, and similar labor are classified in the same industry. In other words, establishments that do similar things in similar ways are classified together. NAICS was introduced in 1997 (replacing most but not all SIC codes) and is periodically revised to reflect changes in the industrial structure of the U.S. and North American economy.

A standard series of four-digit codes created by the U.S. government in 1937 for categorizing business activities. In 1997, the use of SIC codes was replaced in most (but not all) capacities by a six-digit code called the North American Industry Classification System (NAICS). One major government department that still uses SIC codes is the Securities and Exchange Commission (SEC). The SIC codes are listed in a business's electronic data gathering, analysis and retrieval system (EDGAR) filings in order to indicate the industry to which the company belongs.

The following files contain all data from the Bridge Between NAICS and SIC (both tables). Unlike most other reports from the 1997 Economic Census, these data are not accessible in American FactFinder.
