The Los Angeles County Violent Death Reporting System

The Los Angeles County Violent Death Reporting System (LAC-VDRS) monitors the trends and circumstances of violent deaths affecting county residents. These data can inform decision-makers and program planners about ways to prevent and intervene on violence in the community, at home, and in the workplace. This system contributes to the National Violent Death Reporting System (NVDRS).

  • Collects data on violent deaths

    -          Homicides

    -          Suicides

    -          Unintentional firearm deaths

    -          Legal intervention deaths (those caused by law enforcement in the line of duty)

    -          Undetermined intent deaths (those where the cause could not be established)

  • Utilizes multiple sources

    -          Death certificates

    -          Coroner/Medical Examiner reports

    -          Toxicology results

    -          Law enforcement reports

  • Provides comprehensive information

    -          Who is killed (age, race/ethnicity, gender, etc.)

    -          When and where the injury occurred

    -          How the injury occurred (firearm, stabbing, fall, etc.)

    -          What drugs may have contributed (toxicology results for the victim)

    -          What circumstances may have led to the death (fight, gangs, job loss, mental health, etc.)

  • Available data for Los Angeles County

History of NVDRS in LA County

Los Angeles County initially participated in NVDRS from 2006-2008.  CDPH lost NVDRS funding after 2008 because of difficulties in obtaining law enforcement data, but developed their own California Electronic Violent Death Reporting System (CalEVDRS) to continue to collect available data on violent deaths throughout California.  Supported by funding from CDPH, Los Angeles County participated in CalEVDRS from 2010-2016, and when CDPH regained CDC funding in 2017, Los Angeles County again participated in NVDRS.
