About those NAICS numbers at the end of each industry statement
The numbers that appear at the end of each industry statement are North American Industry Classification System (NAICS) codes that define the economic activities covered by each industry in the Career Guide. These codes are from North American Industry Classification System, United States 2002, a manual published by the U. S. Office of Management and Budget. The NAICS Manual 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 NAICS. The NAICS Manual describes the establishment types and goods and services 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 NAICS Manual, which is available in the reference section of many libraries. The NAICS Manual also may be consulted on the Internet at http://www.census.gov/epcd/www/naics.html. This edition of the Career Guide is the third to be classified according to NAICS. Editions prior to the 2004-05 edition classified industries according to the Standard Industrial Classification (SIC), which is no longer being used by Federal statistical programs.
