"We see every year that STEM [science, technology, engineering and math] jobs are rising on the list for a variety of reasons," said Tony Lee, publisher and editor for CareerCast. "Their hiring outlook, salary, better work environment brought on by competition for employees … all walk hand-in-hand to make these jobs more appealing than any others."
CareerCast annually examines the 200 most populated U.S. jobs and then ranks them based on a variety of metrics. Lee said that while there are three health care–related jobs in CareerCast's 2105 Jobs Rated Report, they used to dominate the top of the list. Now STEM jobs have taken over.
"The jobs that are rising into the top 10 are jobs that didn't even exist a few years ago," Lee said.
Also, most of the top 10 jobs in the report are on pace to grow by at least 20 percent between 2012 and 2022.
