We know that women students and staff remain underrepresented in Higher Education STEM disciplines. Even in subjects where equivalent numbers of men and women participate, however, many women are still disadvantaged by everyday sexism. Our recent research found that women who study STEM subjects at undergraduate level in England were up to twice as likely as non-STEM students to have experienced sexism. The main perpetrators of this sexism were not university staff, however, but were men STEM degree students.
That seems to say that there is a slight over-representation of women in STEM (degrees earned) overall but only because of a single subject/job-cluster, “health-related”, with a slight to very large under-representation in all others. No “predominant” anywhere. (well maybe health-related)
