Research for the AASHTO Standing Committee on Planning. Task 63. Making NAICS (North American Industrial Classification System) Work for Transportation

Census data historically have been reported using the Standard Industrial Classification (SIC) System. The North American Industrial Classification System (NAICS) was introduced in 1997 to address a need for a new, more rational approach to tallying industrial classes of workers. There are several differences between NAICS and SIC that make a straightforward comparison difficult. NAICS is based on how products and services are created, while SIC focuses on what is created. The main objective of this report is to analyze the differences between demographic survey data and establishment-based data when they are reported in the same NAICS categories. Specifically, the research focuses on the mismatch between the two databases for the category “Management of Companies and Enterprises”.
