Twenty-Seven schools were surveyed by the American Association of Universities, and over a dozen declined to participate. According to the survey, 25 percent of female undergrads experienced "non-consensual sexual contact through force or in situations when they were incapacitated and unable to consent" at Brown University, and 35 percent of all students said sexual assault and misconduct is very or extremely problematic at the school. At Dartmouth College, those numbers were 28 and 30 percent. At the University of Michigan those numbers were 30 and 29 percent. At Harvard University, those numbers were 26 and 13 percent.
