The job descriptions come from the good people at the U.S. Department of Labor, as published in the most recent edition of the Occupational Outlook Handbook. The OOH is the best source of career information available, and the descriptions include the most current, accurate data on jobs. The figures on earnings have been updated with data from the Occupational Employment Statistics survey. Thank you to all the people at the Department of Labor who gather, compile, analyze, and make sense of this information. It’s good stuff, and we hope you can make good use of it.
