Summary

This study was undertaken to standardize the format of national homicide data and to analyze trends over the period 1968-1978. The unit of analysis is the homicide victim, and variables include information on the reporting agency, the circumstances of the incident, and the characteristics of the victim and the offender. Within these categories are variables pertaining to population and city size, victim's and offender's age, race, and sex, and the number of victims and offenders involved in the incident. Information about the incident includes the type of weapon used and the circumstances surrounding the incident.

Data Collection Notes

  1. The data have been reformatted because of the difficulty in using FBI data as they are released. The reformatting has resulted in the unit of observation (homicide victim) being constant across the study period. The storage mode is "character-numeric." Two major changes in FBI coding of the Supplementary Homicide Reports have resulted in relatively consistent coding within the time periods 1968-1972, 1973-1975, and 1976-1978, but not among them.

ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR performed the following processing steps for this data collection:

  • Standardized missing values.
  • Performed recodes and/or calculated derived variables.
  • Checked for undocumented or out-of-range codes.
