ABSTRACT
The Supplemental Homicide Reports (SHR) are the most widely used data on U.S. homicides. These reports, however, are severely affected by missing data. Drawing upon two recent studies (Pampel and Williams, 2000; Regoeczi and Riedel 2000), the current study uses SHR data and the method of Qualitative Comparative Analysis (QCA) to explore the structure of missing data across combinations of offender, victim, and situational factors. Comparisons of SHR data in the 1976-79 and 1990-98 time periods are conducted to evaluate the nature of change and stablility in the empirical profile of missing data over time. The results are then discussed in terms of their implications on missing data estimation models and further research on the characteristics of homicide trends over time.
