The U.S. Department of Commerce’s Economics and Statistics Administration (ESA) released two reports that profile U.S. employment in the science, technology, engineering, and mathematics (STEM) fields. “STEM: Good Jobs Now and for the Future” reports U.S. growth in STEM jobs overall while “Women in STEM: A Gender Gap to Innovation” finds, as expected, that there are fewer women than men in STEM jobs and attaining degrees in STEM fields as well as a wage disparity based on gender.
Over the past 10 years, growth in STEM jobs was three times greater than that of non-STEM positions. STEM employment is expected to continue to grow at a faster rate than other jobs in the coming decade (see Figure 1). Meanwhile, STEM workers are also less likely to experience joblessness.

Further findings show STEM employees command higher wages, earning 26% more than their non-STEM counterparts. STEM degree holders also enjoy higher earnings, regardless of whether they work in STEM or non-STEM occupations. Likewise, college graduates—no matter what their major—enjoy an earnings premium for having a STEM position.
Through initiatives such as Race to the Top and the “Educate to Innovate” campaign, President Obama has made STEM education a key priority and has laid out an ambitious goal to move U.S. students from the middle of the pack to the top of the pack internationally in science and math achievement over the next decade.
While women make up 48% of the U.S. workforce, only 24% hold STEM jobs. Over the past decade, this underrepresentation has remained fairly constant, even as women’s share of the college-educated workforce has increased.
Women with STEM positions, however, earned 33% more than women in non-STEM jobs in 2009, exceeding the 25% earnings premium for men in STEM. Women in STEM also experience a smaller gender wage gap than their counterparts in other fields.
Engineers make up the most male-dominated STEM occupational group but also the one with the smallest regression-adjusted gender wage gap (see Figure 2). Female engineers earned 7% less per hour than their male counterparts.

According to the “Women in STEM” report, “Physical and life sciences occupations, the most gender-balanced STEM group, have an 8% wage gap, and STEM managers a 9% gap.” Data on materials engineering and materials science are captured within the engineering category.
Several possible factors contribute to the discrepancy of women and men in STEM positions, including a lack of female role models, gender stereotyping, and less family-friendly flexibility in STEM fields. Yet regardless of the causes, the findings of this report offer important evidence to inform policy efforts to encourage and support women in STEM, according to the Department of Commerce.
“We haven’t done as well as we could to encourage young people to go into STEM jobs—particularly women—which inhibits American innovation,” said Acting Secretary of Commerce Rebecca Blank. “Closing the gender gap in STEM degrees will boost the number of Americans in STEM jobs, and that will enhance U.S. innovation and sharpen our global competitiveness.” □
