Research Brief
Women follow a man up a ladder

Women who graduate high school and earn further degrees confront disparities in finding and working in occupations in the burgeoning and well-paying areas of science, technology, engineering, and mathematics — fields collectively known as STEM.

Members of some underrepresented minority groups, even with additional educational credentials, hit some of these hurdles too.

Only 31.1 percent of all bachelor’s degrees awarded to women were in STEM fields, compared with 42.4 percent for men.

About 20 percent of all jobs in the U.S. economy require STEM training. Those occupations are projected to grow about 9 percent over the next decade, faster than any other employment category.

New research and analysis from the nonprofit, nonpartisan RAND Corporation found that women increasingly outpace men in earning the rising number of all types of bachelor’s and associate’s degrees. But they lag in doing so in STEM subjects: In 2015, the most recent year for which data were available, only 31.1 percent of all bachelor’s degrees awarded to women were in STEM fields compared with 42.4 percent for men.

Furthermore, women with STEM degrees do not necessarily land in these fields. Only about 30 percent of women with STEM bachelor’s degrees go on to work in STEM fields compared with 49 percent of men.

Another report finding underscores the uphill climb for women: Men with a non-STEM bachelor’s degree have a slightly higher likelihood of working in a STEM occupation than do women with a STEM bachelor’s degree.

Once they get in STEM occupations, women confront pay disparities, RAND researchers found. They make much more — $10.37 an hour more — than women in non-STEM occupations. But women in STEM occupations earn less — $2.08 an hour less — than men in STEM occupations. However, that is a smaller gap than the $5.62 an hour gender pay difference that women confront in non-STEM occupations. Getting more women into higher-paying STEM occupations, as well as reducing gender pay disparities in the sector, could help reduce the overall gender pay gap.

Comparison of hourly rates of pay between men and women in STEM and non-STEM occupations

Women in STEM occupations earn 6% less — $2.08 an hour less — than men in STEM occupations.

Not all STEM occupations require a bachelor’s degree, but many of these good positions — such as nurses, home health aides, mechanics, engineering technicians, and information technology support — demand licenses and certifications. Women with licenses or certifications, generally speaking, were more likely to find work and earn higher wages than women without such credentials, the RAND study found. The same advantage was found for Hispanics and people who lack high school degrees.

In examining trends by racial and ethnic group, the RAND researchers found that whites and Asians earn most of the STEM bachelor’s degrees and benefit more in terms of wages from their STEM educations than their black and Hispanic peers.
