In 2020, 39% of undergraduate students leaving colleges with degrees in philosophy were women, up from 35% in 2017, reports Eric Schwitzgebel (UC Riverside).
On his blog, The mind burst, Professor Schwitzgebel writes:
Women very regularly represented 30 to 34% of baccalaureate holders in philosophy from 1987 to 2016. In 2017, they reached 35% for the first time. In 2018, 36%. In 2019, 38%. In 2020, 39%. While this may seem like a small increase, given the numbers involved and the general slowness of cultural change, it is a substantial and significant move towards parity. This increase appears to be peculiar to philosophy. For example, it is not cois linked to the overall percentage of female graduates which rose from 51% in 1987 to 57% in 1999 and has remained stable at 57-58% since then.
He notes that the tendency is especially pronounced among those who have philosophy as their second major:
In the last four years of data (2017-2020), 42% of graduates with a second major in philosophy were female, compared to 36% of graduates whose only or major major was in philosophy.
