Juvenile justice is a subfield of criminal justice that focuses on the criminal behavior and legal issues involving individuals who are under the age of 18. The primary goal of juvenile justice is to rehabilitate and reintegrate young offenders into society, rather than simply punishing them. This often involves a combination of social services, counseling, and educational programs in addition to legal consequences. Juvenile justice systems vary by country, but generally have a separate set of laws and procedures designed to address the unique needs of young offenders.
