U.S. Has More Prisoners Than Engineers

If sitting in a prison cell was a job, it would be one of the most common jobs in the United States. In 2012, there were some 1,570,000 inmates in state and federal prisons in the U.S., according to data from the Justice Department. By contrast, there were about 1,530,000 engineers in America last year, 815,000 construction workers, and 1 million high school teachers, according to the Bureau of Labor Statistics.
