Parents reflexively believe that suburban public schools provide children with safer and more wholesome environments than their urban counterparts. This report finds that the comforting outward signs of order and decency in suburban public schools don?t reflect real student behavior. Using hard national data on high school students, this report by Manhattan Institute Senior Fellow Jay P. Greene and Senior Research Associate Greg Forster finds that urban and suburban high schools are virtually identical in terms of widespread sexual activity and alcohol use. Additionally, about 40% of 12th graders in both urban and suburban schools have used illegal drugs, and 20% of suburban 12th graders and 13% of urban 12th graders have driven while high on drugs. Both types of students are about equally likely to engage in other delinquent behaviors such as fighting and stealing. Appended are 34 tables.
