Examining Space–Time Interaction in City-Level Homicide Data: Crack Markets and the Diffusion of Guns Among Youth

This paper examines the linkage between crack market activity and gunhomicide suggested by Blumstein (1995), who argues that the arrival ofcrack stimulated an increased availability of guns among juveniles. Thisgreater availability of guns, the argument continues, is responsible for thesharp upswing in juvenile homicide experienced in the United States in themid-1980s. Using city-level data on crack arrests and gun-related juvenilehomicide, we fit a change-point version of the Bass (1969) model ofinnovation diffusion. We find that, in most large American cities, thediffusion process for crack cocaine experienced an onset of dramatic growththat was followed by a similar, slightly slower growth in gun homicidescommitted by juveniles. We further use cluster analysis to find that thespatial patterning of the two processes is similar, starting on the East andWest Coasts and working their way toward other regions of the nation. Gunuse in homicide among slightly older offenders (ages 18–24) alsoexperienced a change at roughly the same time as the juveniles, but the rateof diffusion was considerably milder than for the younger group; offendersages 25 or older generally show no growth in gun-related homicide whatsoever. In addition, there is no detectable surge in juvenile nongun homicide activity. Based on these findings, we conclude that the crack cocaine markets–gun availability linkage is highly plausible, and we suggest directions for future research in clarifying the dynamics of the late-1980s surge in juvenile homicide.

WHAT'S GOOD FOR THE GAYS IS GOOD FOR THE GANDER: MAKING HOMELESS YOUTH HOUSING SAFER FOR LESBIAN,GAY, BISEXUAL,AND TRANSGENDER YOUTH

Across the United States, lesbian, gay, bisexual, and transgender (LGBT) youth are grossly overrepresented in the homeless youth population. These youth are at an increased risk of being victims of violence in homeless youth housing facilities. This Note examines the causes of the overrepresentation of LGBT youth in the homeless youth population. Additionally, this Note suggests the following changes to the regulation of homeless youth housing programs to make them safer for these youth: (1) placing low maximum limits on the occupancy capacity at which these programs may operate, (2) requiring that all showering facilities provide individual privacy, (3) prohibiting anti‐LGBT discrimination in the provision of services, (4) requiring nondiscrimination and sensitivity training, and (5) promoting the creation of LGBT‐specific homeless youth housing programs.
