Nationwide, family issues still create greater challenges for women than men, Goulden said, despite the "feminizing" trend in academia. In 1966 only 8 percent of doctoral recipients were female compared to about 44 percent today. Yet, among the findings nationally: For each year after receiving a doctorate, married men with children under 6 years are 50 percent more likely to enter a tenure-track position than married women with children under 6.
For each year after securing a tenure-track position, men are 20 percent more likely to achieve tenure than are women.

Tenure and turnover for women faculty reflect disproportional numbers in comparison to men. Fewer than a quarter of all faculty men held temporary appointments as compared with nearly half of all faculty women. The annual separation rate of temporary faculty was about five times the annual separation rate of tenure system faculty. The study concludes that the disproportionate number of women with temporary appointment status accounts for the fact that faculty women have a higher turnover than faculty men.

Among full-time faculty, 38 percent are women. But among full professors, only 23 percent are women. Conversely, women are well-represented among the lower ranks; women are 58 percent of all instructors, 54 percent of all lecturers and hold 51 percent of all unranked positions.

Women occupied about 9 percent of full professor positions at four-year college and universitites in 1972 and still only 23 per cent of all full professors in 2003.
