IU: ~40000 students. Number of on campus forcible sexual assaults in 2012: 27, in 2013: 15 (42 over 2 years)
Purdue: ~39000 students. Number of on-campus forcible sexual assaults in 2012: 2, in 2013: 5 (7 over 2 years)
The dangers are not equivalent even on two similarly sized campuses in two similarly sized metro areas in the same [expletive] state.

(Should one argue that some institutions under-report I shall request data indicating this is so.)
Our DD found this site while researching colleges and removed more than one school from her list because of it.
Candidly, the number of murders in Bloomington is not acceptable. Walking between dorms should not be a capital crime; jogging should not be a capital crime; and partying until drunk, however ill advised, should not carry a death penalty.
As I recall, back when we were looking all around, the crime rate at some highly regarded universities was weirdly variable. For example, Harvard was similar to IU in per 100,000 with about 7 times the number of forcible sexual assaults as Boston U and at least double that of the adjacent MIT.
