The Council of State Governments (CSG) Justice Center has just released Reducing Recidivism and Improving Other Outcomes for Young Adults in the Juvenile and Adult Criminal Justice Systems, an issue brief designed to help state and local officials better support young adults in the juvenile and adult criminal justice systems. Research has shown that young adults ages 18 to 24 stand out as a distinct developmental group with heightened impulsive behavior, risk taking, and poor decision making; and many young adults are disconnected from school and work. These factors increase the odds that a young adult might come into contact with the justice system. Of course, the majority of young adults are not involved in any criminal activity, and those young adults who have committed a crime most often have committed a minor offense. Still, young adults drive a disproportionately large share of criminal justice activity and therefore should be an important focus of juvenile and adult justice systems alike.
