The American Association of University Professors, analyzing data from more than 375,000 full-time faculty members across 900 institutions, said men averaged more than $117,000 in annual salary, $20,800 more than women. Excluding assistant and associate professors and only looking at full-time, full professors, men averaged $156,700, $20,300 more than women—and 65 percent of people at this higher-compensated rank were men. Men have historically made more than women in academe—and for full professors, the gap has widened in recent years. The issue has spawned litigation at a Seven Sisters institution.
