This UI study, the original of which I can't find, is popping up in the slow weekend news:
About 4 percent of University of Iowa students were cited or arrested for criminal offenses in Iowa City between Aug. 1, 2008 and May 20, 2009, according to a UI report.
In the last academic year, 1,194 students were charged with one or more non-traffic criminal offenses in Iowa City, according to numbers gathered by the UI Student Services office.
UI undergraduates had a higher rate of criminal offenses — 5.5 percent — than the overall student body.
Most of the charges — 75 percent of them —were for alcohol-related violations, such as public intoxication and underage drinking.
