At U.S. News, publish an annual ranking of jobs, to analyze some of the most important choices job seekers encounter when selecting a career and to provide context for how jobs within the same industry compare. Our picks share one thing: They're jobs where employment should grow exponentially and faster than the average rate from 2012 to 2022, according to predictions by the U.S. Department of Labor's Bureau of Labor Statistics. For 2014, there have been shake-ups. Though the BLS continues to paint a rosy landscape for some industries, it's also taken a closer look at where opportunity is most expected. What this means for us: We're ranking 18 new jobs this year. Nineteen jobs were bumped from our list entirely. And perhaps the biggest change: For the first time, our No. 1 job overall isn't from the health care industry -- it's a tech job.
