This study was conducted in an effort to better understand the circumstances surrounding murder cases in large urban areas. To evaluate the 75 largest counties in the nation, 33 counties were chosen. The ranking of these counties was based on a combination of crime data and population data. The criteria for including a case on a roster from which cases would be sampled was that (1) one or more defendants must have been arrested for murder and (2) the case must have been adjudicated during 1988. These cases were a sample of about half of all those in the 33 counties studied that had a murder charge brought to the prosecutors in 1988, or earlier, and that were disposed during 1988. When statistically weighted, the sample cases represent a total of 9,576 murder defendants in the nation's 75 largest counties. Demographic information on victims and defendants includes sex, date of birth, area of residence, and occupation. Variables are also provided on the circumstances of the crime, including the relationship between the victim and the defendant, the type of weapon used, the time of death, and the number of victims.
These data are freely available.

Scope of Study
Geographic Coverage: United States
Date of Collection:
Universe: Murder cases adjudicated in 1988 in the 75 largest counties of the United States.
