I have continued my efforts to make sense out of the Clery Act crime data and made a couple more interesting discoveries. In trying to limit noise and floor effects in the data, I’ve been focusing on large 4-year schools with dorms. After eliminating secondary campuses and mislabeled schools, I found 54 universities with at least 30,000 students fitting the other criteria. Even at those big schools, most of the tracked crimes rarely occur. For example, from 2008 to 2012, for any of those 54 schools, there was 1 murder (Virginia Tech, 2009) and 2 manslaughters (Florida State, 2011; Michigan State, 2012). Even data for the tracked crimes of aggravated assault, arson, car theft, non-forcible rape, and robbery at the 54 biggest campuses in the country are so infrequent that any incidents are difficult, if not impossible, to differentiate from noise. That leaves only two Clery Act crimes that are reported to occur with a high enough frequency such that we might hope to learn something comparative about on-campus crime: forcible rape and burglary.
