This paper examines factors that contribute to delinquency or deterrence among high school dropouts. It identifies common characteristics of delinquent dropouts, such as coming from low-income single-parent homes, living in impoverished environments, and having mental health issues. Conversely, dropouts deterred from crime often have commitments to legitimate institutions like work or family that replace school. The paper argues that increasing graduation rates and access to after-school programs could help deter crime and save billions annually spent on the juvenile justice system.
