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 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.
The NAICS & SIC codes are used by many other reference sources as a basis for organizing information. For more information click Here.
Industry ratios provide information that allows the user to determine how well the industry as a whole is doing, how an individual company is performing in comparison to the industry, and how competing companies within an industry compare. Financial information is derived from annual reports and income statements.
