Most literature on juvenile delinquency describes it as essentially a product of the lower socio-economic classes. While there has been some speculation over the incidence and quality of middle-class delinquency, what evidence exists is largely impressionistic. Nevertheless, the prevailing view is that delinquency among middle-class youth has increased in recent years. The present paper seeks a sociological and theoretical perspective to help account for the dominant forms of juvenile delinquency among middle-class youth. It attempts also to explain the emergence and the particular qualities of middle-class delinquency as a consequence of structural changes taking place in the larger society.Accounting for middle-class delinquency in North America requires an understanding of the dominant culture of middle-class youth. Structural changes in society over the last half-century have produced opportunities for extensive adolescent peer-group participation and the emergence of a mass youth culture. During the growth of this youth culture, in which the majority of middle-class teenagers participate, there have emerged, jointly, both delinquent and non-delinquent patterns of behaviour. It is the thesis of this paper that the bulk of middle-class delinquency occurs in the course of customary, non-delinquent activities and falls within the limits of adolescent group norms. Moreover the knowledge of both delinquent and non-delinquent patterns in the youth culture is widely shared among middle-class teenagers. Thus, in order to account for middle-class delinquency one need not look for a separate “delinquent subculture.”
