1997 Economic Census:
Summary Relationships Between NAICS and SIC

The adoption of the NAICS has had a major impact on the comparability of industry data between the 2000 and 1990 censuses of population. The comparability between the SIC (used in 1990) and NAICS (used in 2000) classification systems is most thoroughly explored in the 1997 Economic Census, where each business establishment was coded according both systems. The Sector Descriptions below provide a broad-based summary of each NAICS sector and its SIC components. For more specific industry-by-industry details, see the Bridge Between NAICS and SIC.
