1- Brief descriptions of SIC and NAICS codes

SIC: The Standard Industrial Classification System (SIC) “attempts to classify all business establishments by the types of products or services they make available. Establishments engaged in the same activity, whatever their size or type of ownership, are assigned the same SIC code.”  (Moss & Strauss, 2004)

NAICS: “On April 9, 1997, the Office of Management and Budget (OMB) announced the adoption of a new industry classification replacing the Standard Industrial Classification (SIC)” The objectives of the 1997 revision were to identify new industries and to recognize the system according to a more consistent economic principle, according to the types of production activities performed rather than the mixture of production-based and market- based categories in SIC.” (Moss & Strauss, 2004)
