|This study examines street-level retail drug markets and their location in relationship to facilities in Newark, NJ. Rational choice, routine activity, and environmental theories serve as a guide for determining where drug markets are likely to occur. Using geographic information system (GIS) technology, arrest data from 2001 was analyzed. Density maps were created to identify concentrations of drug arrests, and these locations were then compared to public housing locations, schools, major street arteries, grocery stores, liquor stores, public transportation, and parks. Selected sites were observed to further understand the interaction between these drug markets and the facilities at the location.
