(This is a good point to look toward the sidebar, over there to the left, which has links to more thorough statistics and some of my own analysis. Julie van Camp reliably tracks women in 54 US PhD granting philosophy departments, and her current statistic is 19.6% of full-time faculty are women. Another nice set of statistics is on Sharon Crasnow's blog.)
From the article:
I would only add that the U.S. Department of Education statistics suggest that the gender disparity, at least in the US, does begin at the undergraduate level. Women have only been earning about 30% of bachelor's degrees in philosophy, though they earn more than half of bachelor's degrees overall in all subjects. That difference between women and men is maintained and only slightly widened for master's and doctorate degrees. The gap widens again, and more significantly, at the stages of hiring and tenure.
Much has been done in STEM disciplines to decrease gender disparity. Success in engineering, math, physics, and other sciences has required concerted efforts from universities, professional organizations, and foundations, together with government support in the form of funding research and recruitment programs. The discipline of philosophy has received no similar level of support, and our professional organization has not so far even been able to collect data on hiring and on departmental make-up.
I am skeptical that our discipline will reach contemporary standards of fairness and gender inclusivity until addressing the problem of gender disparity is prioritized by the profession at large--men as well women.
