It has over thirty thousand enrolled students and faculty. Students alone outnumber the non-student population of Blacksburg by three to one. The median age of the "city" (in Virginia, any town which has a government separate from the county it is in is a "city") is about 21, so one could reasonably expect Vice City levels of mayhem.
In 2005, the national murder rate was 5.5 per 100,000. Since this is the first murder in over a year, Virginia Tech is statistically much safer than the national average.
And that's surprising to me, because I well know that while Blacksburg is a fun town with lots of fun people, the weather alone is enough to drive people insane. It rains more or less constantly from September to May, when school is in full session, which leaves students to indoor pursuits such as drinking, screwing, eating food coloring and projectile vomiting as a sport, and occasionally fighting. But oddly enough they don't kill one another nearly as much as one would expect. (One of my housemates threatened to kill me when I was there, but I'm hoping he forgot about it when he sobered up.)
As far as violent crime rates go, Virginia Tech compares favorably against the
University of Massachusetts, Amherst, which is also a huge, hard-drinking school with shitty weather plopped into the middle of a small and comparatively remote town.
