STEM degrees lead to higher salaries and more employment opportunities than other degrees, according to the National Center for Education Statistics (NCES). Despite these economic advantages, only 16 percent of 2008 graduates received a STEM degree. The lack of workers with STEM skills has created a difficult hiring environment for many U.S. firms. A recent Brookings Institution study reveals that the lack of STEM graduates has meant that STEM job postings take twice as long to fill as other postings.

In 2012, U.S. science and engineering graduate programs saw a small 1.7 percent drop in enrollment by U.S. citizens and permanent residents, according to data from the National Science Foundation (NSF). Enrollment by foreign students, however, rose by 4.3 percent. NSF notes that 2012 is the second year in a row that saw very little increase in citizen enrollment, following five years of growth in the range of 2-3 percent.

Groups in the greater Detroit and Pittsburgh regions recently released reports documenting the progress these metros have made over the past few years in building thriving technology economies.
