The Bureau of Labor Statistics (BLS) produces annual occupational employment and wage estimates as part of the Occupational Employment Statistics (OES) program. BLS conducts a semiannual survey of establishments to produce estimates for over 800 industries in the United States. The survey covers all full-time and part-time paid workers in non-farm industries, but does not include self-employed or unpaid workers.

The transportation occupations in table 4-1 and 4-2 cover the following worker types:

• Workers directly employed by a transportation company
• Workers engaged in in-house transportation
• Workers providing services to the transportation industry
• Workers providing transportation for non-transportation government agencies such as school districts

The occupations were selected based on a broad definition of transportation and transportation-related occupations found in Sen, B. and M. Rossetti, "A Complete Count of the U.S. Transportation Workforce," Transportation Research Record 1719: 2000, pp 259-266.
