ABSTRACT
Research on homicides has shown that understanding the characteristics of a crime through the development of a typology can prove useful for defining intervention strategies and guiding policy decisions. The same principals apply to other crimes such as aggravated assault. However, the development of a clear typology requires incident level data. For homicides national incident level data has been available since the introduction of the Supplemental Homicide Reports in 1961. Until recently incident level data for one offense like aggravated assault has not been available at the national level. The FBI's National Incident-Based Reporting System (NIBRS) provides the incident level details necessary to develop a typology of aggravated assaults. The current project uses NIBRS data for the years 2000 and 2001 to develop a typology of aggravated assaults. The research has three objectives: 1) to demonstrate the utility of the FBI's NIBRS data for incident level analysis, 2) to demonstrate the utility of the FBI's NIBRS data for developing a typology of aggravated assault, and 3) use the typology of aggravated assaults for a discussion of the policy implications and intervention strategies.
