The purpose of the study was to provide data for a sample of serious assaults in three cities: Miami, Florida, Pittsburgh, Pennsylvania, and St. Louis, Missouri.
Working from a common coding scheme, the data were extracted from police offense reports by independent research teams working in each city. The data include detailed information about the incident (Part 1) and participants (Parts 2-9) for a sample of incidents occurring over a specified time range in each city. The data for Miami are from 327 incidents occurring from years 1996-1997 while those from Pittsburgh (524 incidents) are from 1994-1996 and those from St. Louis (504 incidents) are from years 1995-1996. The data include a sample of serious assaults that was stratified to over-represent females among victims and offenders.
Data are available for 1,355 unique incidents (Part 1), of which 327 incidents took place in Miami, 504 in St. Louis, and 524 in Pittsburgh. The other parts are broken down into data about the 1,273 suspects (Part 5), 1,857 victims (Part 2) and 503 witnesses (Part 9) associated with those incidents. The Victim's Relationship with Suspect Data (Part 3) contain information on 1,743 victim/suspect relationships. The Witness Relationship with Victim Data (Part 4) contain information on 332 witness/victim relationships. The Witness Relationship with Suspect Data (Part 8) contain information on 262 witness/suspect relationships. The Suspect Charge-Arrest Data (Part 6) contain information on 611 arrests. The Suspect Charge-Warrant Data (Part 7) contain information on 661 arrest warrants.
