Data analysis confirms that, following the ordinance, the proportion of arrests involving out of town patrons to in town patrons was significantly reduced (Fisher's exact test, p 5 0.0001). Similar results were obtained for only under 21 arrests (Fisher's exact test, p0 0.0095) and over 21 arrests (Fisher's exact test, p 0 0.0058), suggesting that the campus bars were equally attractive to all age groups prior to the ordinance.
