The term "delinquency" is a general term meaning against normal behavior. How this term is applied is according to what type of industry uses the term. For example the credit industry uses delinquency to mean that someone hasn't paid his bill or isn't making his payment on time according to the terms of the agreement. In the criminal justice industry it is used primarily for juvenile delinquency, meaning that a child is not behaving the way he is expected to behave according to society. In the juvenile justice system children don't commit crimes: they commit "acts of delinquency," which is why juveniles are handled in a different way from adults, and are given a second chance when they become adults if they meet other criteria. Adults, on the other hand, are not "delinquent' They are either convicted felons or persons with a criminal history. Or they can be traffic offenders, "deadbeat dads/moms," or fit other classifications of criminal behaviors.
Delinquency refers to a behavior, typically exhibited by young people, that involves violating laws or rules. It often involves criminal activities or antisocial behavior, such as theft, vandalism, or drug use. Delinquency is considered a concern because it can lead to negative consequences for the individual and society.
