The North American Industry Classification SystemFor over sixty years, the Standard Industrial Classification (SIC) system has served as the structure for the collection, aggregation, presentation, and analysis of the economy. An industry consists of a group of establishments primarily engaged in producing or handling the same product or group of products or in rendering the same services. Industry definitions used in the Bureau of Labor Statistics programs come from the 1987 Standard Industrial Classification (SIC) Manual. Because the SIC is used by many other federal government statistical programs, it is possible for users to assemble a comprehensive statistical picture of an industry. Developed in cooperation with and , the North American Industry Classification System (NAICS) represents one of the most profound changes for statistical programs focusing on emerging economic activities. NAICS, developed using a production-oriented conceptual framework, groups 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.
