Surveillance for violent deaths--National Violent Death Reporting System, 16 states, 2009.

PROBLEM/CONDITION: An estimated 50,000 persons die annually in the United States as a result of violence-related injuries. This report summarizes data from CDC's National Violent Death Reporting System (NVDRS) regarding violent deaths from 16 U.S. states for 2009. Results are reported by sex, age group, race/ethnicity, marital status, location of injury, method of injury, circumstances of injury, and other selected characteristics.

REPORTING PERIOD COVERED

DESCRIPTION OF SYSTEM

NVDRS collects data regarding violent deaths obtained from death certificates, coroner/medical examiner reports, and law enforcement reports. NVDRS data collection began in 2003 with seven states (Alaska, Maryland, Massachusetts, New Jersey, Oregon, South Carolina, and Virginia) participating; six states (Colorado, Georgia, North Carolina, Oklahoma, Rhode Island, and Wisconsin) joined in 2004, four (California, Kentucky, New Mexico, and Utah) in 2005, and two (Ohio and Michigan) in 2010, for a total of 19 states. This report includes data from 16 states that collected statewide data in 2009. California is excluded because data were collected in only four counties. Ohio and Michigan are excluded because data collection did not begin until 2010.

RESULTS

For 2009, a total of 15,981 fatal incidents involving 16,418 deaths were captured by NVDRS in the 16 states included in this report. The majority (60.6%) of deaths were suicides, followed by homicides and deaths involving legal intervention (i.e., deaths caused by police and other persons with legal authority to use deadly force, excluding legal executions) (24.7%), deaths of undetermined intent (14.2%), and unintentional firearm deaths (0.5%). Suicides occurred at higher rates among males, non-Hispanic whites, American Indians/Alaska Natives, and persons aged 45-54 years. Suicides occurred most often in a house or apartment and involved the use of firearms. Suicides were preceded primarily by mental health, intimate partner, or physical health problems or by a crisis during the previous 2 weeks. Homicides occurred at higher rates among males and persons aged 20-24 years; rates were highest among non-Hispanic black males. The majority of homicides involved the use of a firearm and occurred in a house or apartment or on a street/highway. Homicides were preceded primarily by arguments and interpersonal conflicts or in conjunction with another crime. Characteristics associated with other manners of death, circumstances preceding death, and special populations also are highlighted in this report.

INTERPRETATION

This report provides a detailed summary of data from NVDRS for 2009. The results indicate that violent deaths resulting from self-inflicted or interpersonal violence disproportionately affected adults aged <55 years, males, and certain racial/ethnic minority populations. For homicides and suicides, relationship problems, interpersonal conflicts, mental health problems, and recent crises were among the primary factors that might have precipitated the fatal injuries. Because additional information might be reported subsequently as participating states update their findings, the data provided in this report are preliminary.

PUBLIC HEALTH ACTION

For the occurrence of violent deaths in the United States to be better understood and ultimately prevented, accurate, timely, and comprehensive surveillance data are necessary. NVDRS data can be used to monitor the occurrence of violence-related fatal injuries and assist public health authorities in the development, implementation, and evaluation of programs and policies to reduce and prevent violent deaths at the national, state, and local levels. The continued development and expansion of NVDRS is essential to CDC's efforts to reduce the personal, familial, and societal costs of violence. Additional efforts are needed to increase the number of states participating in NVDRS, with an ultimate goal of full national representation.
