This report contains information on arrest volume, rates, and trends throughout the State. In addition, it presents information on arrestee characteristics for five separate crime categories: violent, property, drug, "society," and "other." The report is presented in three main sections: all arrests, adult arrests, and juvenile arrests. Within each of these sections, data are further broken down by crime types. For each crime type, figures and tables show volume, rates, and trends. Between 2008 and 2009, Wisconsin had a slight decrease in the number of total arrests. Arrests for violent offenses decreased 4 percent, and the number of property-crime arrests decreased 5 percent.
