As the problem of crime continues to worsen in the 1980s, the need for up-to-date, comprehensive information on its dynamics and incidence increases. This work, the fourth in a four-volume series, is the first study to focus exclusively on demographic trends in criminality and victimization for crime as a whole. Concerned with the broad picture of crime in America as well as specific demographic correlates and characteristics, it develops profiles of patterns in criminality and suggests ways of applying this demographic data to promote more effective crime control.
