National Violent Death Reporting System
Data Collection and Access
The National Violent Death Reporting System (NVDRS) collects existing data from four major sources:
- death certificates;
- coroner/medical examiner reports;
- police reports; and
- crime laboratories.
NVDRS collects detailed information on victims and offenders, including:
- demographics;
- substance use;
- relationship of victim to offender;
- circumstances leading to the injury;
- whether the event occurred at home or work;
- date and location of the incident; and
- weapon type.
An incident-based, relational database collects and stores the data and is available free of charge from WISQARS NVDRS (see below). Â Unlike the existing national data systems, such as death certificates and the Federal Bureau of Investigation's Supplementary Homicide Reports, NVDRS can identify specific subtypes of violence, such as combination murder-suicides and assault weapon shootings, and can identify cases of intimate partner violence and child abuse deaths with more precision. Data are available to researchers, policymakers, and others so they can better understand and evaluate avenues to prevent interpersonal violence and suicide.
Data about the victim, mechanism of injury/death, incident circumstances, and potential suspects can be used to better understand the potentials and limits of education, mental health and social services, safety regulations, and criminal prosecution in reducing and preventing various violent injuries.
WISQARS NVDRS
WISQARS is an interactive query system that provides data on fatal and nonfatal injuries in the United States. The WISQARS NVDRS module provides detailed information on violent death from NVDRS. Data are available from participating states for violence-related deaths, including incident counts, and crude and age-adjusted death rates by manner of death and cause of injury.

Restricted Access Datasets
Restricted data contain confidential information that could lead to disclosure of the identity of suspects and victims. CDC protects these data by maintaining them on a secure, non-networked server. Individuals who apply for and complete a restricted access data agreement may obtain access to these data for legitimate research purposes. The application and agreement spell out the conditions of use pertaining to confidentiality and the measures required for keeping the restricted datasets physically safe when in the researcher's possession.
