Although recent empirical research questions the conclusion that crime is highest in the lower class, this empirical literature is plagued by limited measures of social class or of crime and by a failure to study systematically the effect of social class on crime in the adult general population. The present work was undertaken in an attempt to rectify many of the inadequacies of the class-crime research. Self-report data were collected from a general population of adult residents in a large, midwestern city and were analyzed to assess the effects of a wide range of class measures on crime measures. The overall results produced from a sample of 555 adults demonstrated that regardless of how class or crime were measured, social class exerted little direct influence on adult criminality in the general population. Consistent with research findings from nonself-report studies, social class was related to criminal involvement for nonwhites.
