Back in 2017, I noticed that the percentage of women philosophy majors in the U.S. had been 30%-34% for "approximately forever". That is, despite the increasing percentage of Bachelor's degrees awarded to women overall and in most other majors, the percentage of philosophy Bachelor's degrees awarded to women had been remarkably steady from the first available years (1986-1987) in the NCES IPEDS database through the then-most-recent data year (2016).
