Highlights of Findings From the Denver Youth Study (FS 99106) April 1999 Fact Sheet 2 page(s) Browning, K., Huizinga, D. Presents findings from the Denver Youth Survey, a longitudinal study of urban youth. The study, one of three coordinated projects supported by OJJDP since 1986 through its Program of Research on the Causes and Correlates of Delinquency, explored changes in the nature of delinquency and drug use from the 1970's to the 1990's. The study revealed that overall there was little change in the prevalence rates of delinquency although the level of injury from violent offenses increased substantially. The relationship between drug use and delinquency has changed; the prevalence of drug use decreased substantially, and a smaller percentage of serious delinquents are using hard drugs. PDF Text
