A study from the ASA conference explored the data on gender and tenure in computer science, sociology and English.

Not only are men more likely than women to earn tenure, but in computer science and sociology, they are significantly more likely to earn tenure than are women who have the same research productivity. In English men are slightly (but not in a statistically significant way) more likely than women to earn tenure….

In sociology, she found that the odds of a woman earning tenure were 51 percent lower than for men, when controlling for research productivity. In computer science, the figure was 55 percent. Those gaps are “highly significant,” she said. These figures suggest, Weisshaar said, that it’s not that women have to find ways to become as productive as men, but that women must be more productive than men if they want to earn tenure at a research university.
