National Violent Death Reporting System
The goal of the National Violent Death Reporting System (NVDRS) is to provide communities with a clearer understanding of violent deaths so that they can be prevented. The system's objectives are to link records on violent deaths that occurred in the same incident to help identify risk factors for multiple homicides or homicide-suicides; to provide timely preliminary information on violent deaths through faster data retrieval; to describe in detail the circumstances that may have contributed to a violent death; and to better characterize perpetrators, including their relationships to victim(s). NVDRS collects and consolidates data on violent deaths from a variety of sources including death certificates, coroner/medical examiner reports, police reports, and crime laboratories.
