02639 Victimization Patterns in Los Angeles: Who is at High Risk of Gang Violence and Where Does It Occur? Kiminori Nakamura Mentor: George Tita In order to understand the nature of gangs and their activities, one cannot avoid the issue of their territoriality. We explore the question: Is one’s place of residency associated with one’s gang territory? The answer to this question bears considerable weight in terms of the impact of gang violence on communities. If gang members spend most of their time in their gang territory instead of the neighborhood where they live, then communities where gangs hang out should be more susceptible to gang violence than the communities where they reside. The current study employs a quantitative approach by using the spatial typology of homicide developed by Tita and Griffiths (2003). The spatial typology categorizes homicide incidents based on the spatial relationship between offender’s residence, victim’s residence, and location of the incident. We extend the typology to not only examining the residence of known gang members involved in homicide, but also where the turf of the gang member is located. The data we employ contain information on all homicides for the period 1990–2000 in two areas of Los Angeles: The Hollenbeck and the Southeast policing districts. We expect to find a noticeable contribution of territoriality information to the spatial typology. The potential findings could have implications for solutions to gang violence.
