The topic of youth, violence, and disintegration needs addressing because young women and men are the world's greatest capital. They have the energy, talent, and creativity for building a future. But this group also suffers grave vulnerabilities. The time of adolescence includes important and difficult periods of life (for example, becoming more independent from the family, finding an adequate position in society, and starting a family of one's own). All of these points are strongly correlated with social integration, employment, and a place in the labor market--important factors in this context. This article gives an overview of the international development and the actual situation of socially harmful behavior among youths--both fatal violence (homicide) and nonfatal violence (such as bullying, fighting, and carrying weapons). The author shows that different kinds of youth violence represent social problems in every society. The data show that youths are not only perpetrators but also the group with the highest risk of becoming victims of violence. Furthermore, the data from around the world show that their vulnerability is not limited to this sphere. It arises also from their social conditions, especially their high risk of being disintegrated from the labor market. The parallels in the data underline the significance of a functioning institutional structure without positing a deterministic relationship between the risk of economic disintegration and violent behavior.
