Ah, you're focusing on the "on campus" part, not necessarily the estimate.  Got it.  Yes, most victimization estimates of college students include both on and off campus incidents.  Other studies have shown that campus serves as a nexus — victims and offenders frequently meet on campus.

You're also right that such victimization estimates speak to broader cultural issues and we shouldn't limit our discussion to students or university campuses.  But universities are uniquely positioned to 1) have an open, honest discussions about consent; 2) educate both men and women on issues related to consent; and 3) provide services and support to victims. Historically, universities have not done any of these things nearly well enough.
