For STEM majors, the data are clear-cut. Just take a look at MIT/Caltech/Harvey Mudd, where nearly all applicants are STEM majors. For all three schools, the male/female applicant ratios are about 3:1. However, the male/female acceptance ratios are almost exactly 1. So a female applicant is three times more likely to be accepted than a male applicant. But it’s not an Asian thing. It’s across all ethnicities.
