No. 3 fastest-growing career: Biomedical engineer
Projected 2010-20 growth:
America's growing elderly population is creating lots of work for biomedical engineers, who develop cutting-edge medical devices.
"With the aging baby boom generation, there should be increased demand for hip replacements, knee replacements and other things that biomedical engineers work on," Morisi says.
She adds that biomedical engineers also help design advanced computer systems for medical record-keeping -- another "hot" product area.
As a result, the BLS predicts the number of biomedical-engineering jobs will grow by more than 60% this decade.
But like rebar work, the biomedical-engineering field is small -- so the profession (median pay: $84,670) will only add 9,700 jobs in numeric terms.
Biomedical engineers also need the most education of any workers on the list of fast-growing occupations
Most jobs require a bachelor's degree in biomedical engineering, or an undergraduate degree in some other engineering discipline plus a biomedical-engineering graduate degree or on-the-job experience.
