A stunning number of U.S. colleges -- nearly 89 percent -- reported zero incidents of rape in 2015, according to the American Association of University Women (AAUW) analysis of data provided by schools to the U.S. Department of Education. But don't let that statistic fool you-- the key word being "reported." Just because a school had no rape reports doesn't mean that no rapes happened.
A 2014 report by the U.S. Department of Justice estimated that nearly 80 percent of student victims don't report their rape or sexual assault to police based on data from 1995 to 2013, USA Today noted.
Other studies more likely depict a more accurate picture of sexual assault on college campuses. According to a 2011 survey by Fifth & Pacific and Knowledge Networks found that more than one in five students said they had experienced sexual abuse, accompanied with physical abuse and threats of physical violence.
The reasons why victims refrain from reporting instances of sexual assault are wide-ranging. Twelve percent of victims said they felt their assaults weren't important enough to report to police, the DOJ noted. Other reasons include fears of not being believed or even being shamed.
