This course offers an overview of sociological theory and research on juvenile delinquency. We start by critically examining the social facts surrounding the measurement, extent, and distribution of delinquency. Next, we study the principal sociological explanations of delinquent behavior. These theories provide conceptual tools for analyzing monographs detailing delinquency among groups such as street gangs. Throughout, we analyze the success or failure of key programs implemented in attempts to reduce delinquency. The main objectives include, understanding the measurement of delinquency, the extent and distribution of delinquent behavior according to these measures. In addition, the course helps students acquire a working knowledge of the key sociological theories of delinquency. Students will also learn to apply the conceptual tools of these theories to selected case studies, and to have a critical evaluation of concrete policy responses to delinquency.
