Gun violence may be relatively rare on university campuses in the United States (see Nature 505, 150–152; 2014), but other violent incidents are rampant.

Acts of sexual violence, for example, are committed against an estimated 20–25% of females attending a US college or university (see C. J. Vladutiu et al. Trauma Violence Abus. 12, 67–86; 2011). According to the US Census Bureau, roughly 11,658,000 women were enrolled in higher-education institutions in 2009. Assuming 20% victimization, as many as 2,331,600 of those could have been sexually assaulted on campus.
