National Violent Death Reporting System

Data Access

NVDRS data are stored in an incident-based, relational database. Descriptive data can be accessed free of charge from NCIPC’s Web-based Injury Statistics and Query System (WISQARS). More detailed data from the NVDRS Restricted Access Database (RAD) is available by request for users meeting certain eligibility criteria.

WISQARS Violent Deaths (NVDRS) Module

WISQARS is an interactive query system that provides data on fatal and nonfatal injuries in the United States. Any data user can access WISQARS online.

The NVDRS module in WISQARS provides descriptive information on violence-related deaths available from participating states. The query system provides incident counts as well as crude and age-adjusted death rates by manner of death and cause of injury. Also, queries can be tailored to include states, years, age ranges, sex, and racial or ethnic groups of interest. Visit WISQARS NVDRS online for more information.

NVDRS Restricted Access Database (RAD)

The NVDRS Restricted Access Database (RAD) is a de-identified, multi-state, case-level microdata set comprised of hundreds of unique variables. The database uses short narratives to describe the circumstances related to violent deaths, including descriptions from law enforcement and medical examiner or coroner investigative reports.

The RAD contains confidential information that could lead to disclosure of the identity of suspects and victims. CDC protects these data by requiring users to meet certain eligibility requirements and to take steps necessary to ensure the security of data, preserve confidentiality, and prevent unauthorized access to these data.  

Learn more about these data and obtain information about the application process on the Restricted Access Database page.
