Although women make about half of the workforce in the U.S., women in STEM remain underrepresented. These numbers have seen a slight increase, however.

According to Pew Research, women make up 40% of the nation’s physical scientists. They are 48% of life scientists, compared with 47% in 2016. Women’s representation among mathematical workers has also slightly increased (46% to 47%).

Pew’s research also shows that women have increased their share of employment in some of the higher profile health-related STEM occupations. Women are 38% of physicians and surgeons and 33% of dentists. Among optometrists, 46% are women and 64% are veterinarians. Lastly, women make up 33% of EMTs and paramedics.

Women are more largely represented in medical occupations, according to Pew Research.

When it comes to race, Black and Hispanic people remain underrepresented. Although Hispanics make up 17% of total employment across all occupations, only 8% are in STEM occupations.

Black workers, who comprise 11% of total employment across all occupations, are 9% of STEM workers.

Although some changes have been made since 2016, there is still work to be done when it comes to representation in STEM. Programs like Girls 4 Science aim to close this gap.
