The number of U.S.-trained female science, engineering, or health (SEH) doctorate holders residing and working in the U.S. has more than doubled, going  from 119,350 in 1997 to 287,250 in 2017, according to a new report from the National Science Foundation (NSF). In 1997, less than one-fourth (23 percent) of the U.S.-trained SEH doctorate holders working in the U.S. were women. Twenty years later, that number had increased to 35 percent.
