About those SIC numbers...
The numbers in parentheses that appear below each industry title are Standard Industrial Classification (SIC) codes that define what is covered by each industry in the Career Guide. These codes are from the 1987 edition of the Standard Industrial Classification Manual, a publication of the Federal Office of Management and Budget that defines and names industries and establishes a structure for relating industries to one another. All statistics on industries produced by the Federal Government are collected in accordance with the SIC. The SIC Manual describes the establishment types and goods produced in each of the specific industries covered in the Career Guide. Readers interested in obtaining more detailed definitions of the industries in the Career Guide should consult the SIC Manual, which is available in the reference section of many libraries. The SIC Manual may also be consulted on the internet at www.osha.gov/oshstats/sicser.html.
