Standard Industrial Classification (SIC)
The SIC system begins with nine major categories -- agriculture, forestry, and fishing; mining; construction; manufacturing; transportation, communications, and public utilities; wholesale trade; retail trade; finance, insurance, and real estate; and services. These groups are divided into two-digit codes, then broken down to three-digit industry groups and finally into four-digit industry codes. SIC is predecessor of NAICS and is still widely used.
