|The most exciting table I've seen since breakfast.|
Some useful figures to get started with:
- Roughly 30,000 students attend GMU, 7,000 of them on living on campus.
- From the BJS, around 35% of property crimes and 45% of violent crimes are reported to the police.
So, to get a quick back-of-the-envelope calculation on risk of a certain crime you could take the number reported above (averaging across the three years to be fancy), multiply by three for property crimes or two for violent crimes, and then divide by 30,000. That would give the raw chance for any one individual becoming a victim of that crime. For example, burglary: 20.67 burglaries were reported per year, and if that's only 35% of the total we expect the true number to be about 62. Divide that by 30,000 and you find a 0.2% chance of being burglarized at GMU in a given year.
If a student was wondering about the chance of being caught for drinking on campus, they could perform a similar exercise. An average of 647 students get referrals or arrests for alcohol per year. From a resident student population of 7,000 we might assume 75% are underage (if everyone starts college at age 18, and stays 4 years) and nationally, 82% of underage college students report drinking in the last year. Taking one extreme, if we assume that all students caught drinking are underage, the chance of being caught for drinking is about 15% as an upper bound. If instead we assume that students above the legal age may also be arrested or referred for drinking, and that everyone drinks (an extreme belief indeed) then the chance of being caught drinking in a year is 9%.
If caught, about 40% are arrested if caught on campus, with the rest getting referrals. Of course, common sense would indicate that acting drunk and stupid in public can sway those probabilities in a dramatic fashion. It's also worth noting that students caught for drinking in the student residences were much more likely to get referrals, rather than being arrested.
In other respects, these figures are less helpful. Looking at "Nonforcible Sex Offenses" there are none reported in any of the last three years. While I would like to say this proves that GMU students are paragons of virtue and would never take sexual advantage of each other, it is more likely that these offenses just go unreported. How many such crimes occur at any college is a hotly debated question, which is important to address but very hard to answer conclusively.
Overall, I'd say that GMU's Annual Security Report paints a fairly pleasant picture of crime risks on campus, and justifiably so -- anecdotally, the George Mason area and Fairfax in general are probably the safest places I've lived yet. Compared to my undergraduate institution, Gonzaga University, which had a rash of stick-up robberies by two teenage thugs with shotguns during one year, GMU-Fairfax seems pretty rosy. It's no reason for complacency, but safety-conscious parents or students should take some comfort in knowing that their lives and property are pretty well-protected when attending George Mason.
