Goals of the HRWG were identified as follows: to forge links between research, epidemiology, and practical programs to reduce violence-related mortality; to improve data quality and the linking of diverse homicide data sources; to foster interdisciplinary research on lethal and nonlethal violence; to encourage more efficient sharing of techniques for measuring and analyzing homicide; to create and maintain a communication network among those collecting, maintaining, and analyzing homicide data sets; and to generate a stronger working relationship among homicide researchers. HRWG meeting sessions focused on important homicide data sets, characteristics of victims and offenders, geographic distribution and area characteristics of homicide, and specific factors in homicide. Meeting participants considered the relationship of theory and policy to homicide and future efforts to study homicide and violence. A brief history of the HRWG is included.
