Summary from this article:
"Despite making up nearly half of the U.S. workforce, women are still vastly underrepresented in the science, technology, engineering and math (STEM) workforce.
Women made gains – from 8% of STEM workers in 1970 to 27% in 2019 – but men still dominated the field. Men made up 52% of all U.S. workers but 73% of all STEM workers."
