California Data Sources

  • EpiCenter - IVPB's online injury data system, is an online data query system on injury and violence-related deaths, hospitalizations, and emergency department visits in California.
  • California Violence Death Reporting System (CalVDRS) - CalVDRS starts with basic demographic information collected by CDPH through death certificate data and links this to comprehensive death data from medical examiners and coroners (including investigative reports, toxicology information, and medical history) and reports from law enforcement (such as weapon information and circumstances of the incident). While data is not yet available from this project, to find out more about current CalVDRS data collection, contact IVPB at  or visit the Centers for Disease Control and Prevention National Violence Death Reporting System.
