There has been an increase in juvenile delinquency, not only in the countries devastated by war which suffered misery and famine, but also in those countries not directly touched by its ravages.

In the etiology of juvenile delinquency, the break-up of the family plays the greatest role. This is studied in relation to its contributory factors such as military service, forced labor, and other causes which were responsible for the separation of children from their parents.

The war increased aggressive behavior and feelings of hate. In the countries dominated by the Nazis there was a complete dissolution of all moral principles. In addition to poverty and hunger, the continuous propaganda, inciting contempt and hatred, allowing mass murder and pillage, shattered the basic morality of the youth.

The demoralization and the increase of juvenile delinquency will probably last for a long time, especially in those countries which suffered in the extreme under the Nazi occupation.
