Table 1. Number, percentage,* and rate of suicides among persons aged ≥10 years,§ by selected demographic characteristics of decedent, method used, and location in which injury occurred — National Violent Death Reporting System, 39 states and the District of Columbia, 2018**

* Percentages might not total 100% due to rounding.
Per 100,000 population.
§ Suicide is not reported for decedents aged <10 years, as per standard in the suicide prevention literature. Denominators for suicide rates represent the total population aged ≥10 years.
Sex was unknown for two decedents.
** Data for all violent deaths were collected in 36 states (Alabama, Alaska, Arizona, California, Colorado, Connecticut, Delaware, Georgia, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, Nebraska, Nevada, New Hampshire, New Jersey, New Mexico, New York, North Carolina, Ohio, Oklahoma, Oregon, Pennsylvania, Rhode Island, South Carolina, Utah, Vermont, Virginia, Washington, West Virginia, and Wisconsin), and the District of Columbia. Three states (California, Illinois, and Pennsylvania) collected data from a subset of counties in their state. Data for violent deaths that occurred in Illinois include 28 counties that represent 86% of the state’s population (Adams, Boone, Champaign, Cook, DuPage, Effingham, Fulton, Kane, Kankakee, Kendall, Lake, Lasalle, Livingston, Logan, McDonough, McHenry, McLean, Macoupin, Madison, Peoria, Perry, Rock Island, St. Clair, Sangamon, Tazewell, Vermillion, Will, and Winnebago). Data for violent deaths that occurred in Pennsylvania include 39 counties that represent 82.2% of the state’s population (Adams, Allegheny, Armstrong, Beaver, Berks, Blair, Bradford, Bucks, Cambria, Carbon, Centre, Chester, Clarion, Clearfield, Clinton, Columbia, Crawford, Dauphin, Delaware, Fayette, Forest, Greene, Indiana, Jefferson, Lackawanna, Lancaster, Lehigh, Luzerne, Monroe, Montgomery, Montour, Northampton, Philadelphia, Schuylkill, Union, Wayne, Westmoreland, Wyoming, and York). Data for violent deaths that occurred in California include 21 counties that represent 54% of the state’s population (Amador, Butte, Fresno, Humstrongt, Imperial, Kern, Kings, Lake, Los Angeles, Marin, Mono, Placer, Sacramento, San Benito, San Diego, San Francisco, San Mateo, Shasta, Siskiyou, Ventura, and Yolo). Denominators for the rates for these three states (California, Illinois, and Pennsylvania) represent only the populations of the counties from which the data were collected.
†† Rate is not reported when the number of decedents is <20 or when the characteristic response is “other” or “unknown.”
§§ Includes persons of any race.
¶¶ Other location includes (in descending order) office building; abandoned house, building, or warehouse; synagogue, church, or temple; bar or nightclub; and other unspecified location.

§ The following statement can be used as a general guide for interpreting the victim-suspect relationship: “The victim is the [insert relationship] of the suspect.” For example, when a parent kills a child, the relationship is “child,” not “parent” (The victim is the child of the suspect.). Some relationships might not be captured by this sentence (e.g., if the other person is known to the victim or if the victim was a law enforcement officer killed in the line of duty).
Data for all violent deaths were collected in 36 states (Alabama, Alaska, Arizona, California, Colorado, Connecticut, Delaware, Georgia, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, Nebraska, Nevada, New Hampshire, New Jersey, New Mexico, New York, North Carolina, Ohio, Oklahoma, Oregon, Pennsylvania, Rhode Island, South Carolina, Utah, Vermont, Virginia, Washington, West Virginia, and Wisconsin), and the District of Columbia. Three states (California, Illinois, and Pennsylvania) collected data from a subset of counties in their state. Data for violent deaths that occurred in Illinois include 28 counties that represent 86% of the state’s population (Adams, Boone, Champaign, Cook, DuPage, Effingham, Fulton, Kane, Kankakee, Kendall, Lake, Lasalle, Livingston, Logan, McDonough, McHenry, McLean, Macoupin, Madison, Peoria, Perry, Rock Island, St. Clair, Sangamon, Tazewell, Vermillion, Will, and Winnebago). Data for violent deaths that occurred in Pennsylvania include 39 counties that represent 82.2% of the state’s population (Adams, Allegheny, Armstrong, Beaver, Berks, Blair, Bradford, Bucks, Cambria, Carbon, Centre, Chester, Clarion, Clearfield, Clinton, Columbia, Crawford, Dauphin, Delaware, Fayette, Forest, Greene, Indiana, Jefferson, Lackawanna, Lancaster, Lehigh, Luzerne, Monroe, Montgomery, Montour, Northampton, Philadelphia, Schuylkill, Union, Wayne, Westmoreland, Wyoming, and York). Data for violent deaths that occurred in California include 21 counties that represent 54% of the state’s population (Amador, Butte, Fresno, Humboldt, Imperial, Kern, Kings, Lake, Los Angeles, Marin, Mono, Placer, Sacramento, San Benito, San Diego, San Francisco, San Mateo, Shasta, Siskiyou, Ventura, and Yolo). Denominators for the rates for these three states (California, Illinois, and Pennsylvania) represent only the populations of the counties from which the data were collected.
** Rates are not reported when the number of decedents is <20 or when the characteristic response is “other” or “unknown.”
†† Includes persons of any race.
§§ Other location includes (in descending order) office building; preschool, school, college, or school bus; synagogue, church, or temple; industrial or construction area; hospital or medical facility; farm; railroad tracks; cemetery, graveyard, or other burial ground; bridge; and other unspecified location.
¶¶ Percentage is based on the number of homicide decedents with a known victim-suspect relationship (n = 5,725 [42.6%]; 3,863 [36.4%] males and 1,862 [65.8%] females); victim-to-suspect relationship was unknown for 7,716 decedents.
*** Includes adoptive family members (e.g., adopted child), stepfamily members (e.g., stepparent), and foster family members (e.g., foster child).
††† Other relationship includes (in descending order) the victim was a law enforcement officer injured in the line of duty, and victim was an intimate partner of suspect's parent (e.g., teenager kills mother’s boyfriend).

* Percentages might not total 100% due to rounding. There were 12,693 homicide incidents overall and 9,331 suspects from 8,051 incidents with suspect information. Of the total number of homicide incidents, 6,071 (47.8%) had known suspect age, resulting in 7,331 suspects (age was unknown for n = 2,600 (26.2%) of suspects). Some incidents had >1 suspect. Denominators for suspect characteristics and circumstances vary by the availability of known information and are specified in separate footnotes.
Data for all violent deaths were collected in 36 states (Alabama, Alaska, Arizona, California, Colorado, Connecticut, Delaware, Georgia, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, Nebraska, Nevada, New Hampshire, New Jersey, New Mexico, New York, North Carolina, Ohio, Oklahoma, Oregon, Pennsylvania, Rhode Island, South Carolina, Utah, Vermont, Virginia, Washington, West Virginia, and Wisconsin), and the District of Columbia. Three states (California, Illinois, and Pennsylvania) collected data from a subset of counties in their state. Data for violent deaths that occurred in Illinois include 28 counties that represent 86% of the state’s population (Adams, Boone, Champaign, Cook, DuPage, Effingham, Fulton, Kane, Kankakee, Kendall, Lake, Lasalle, Livingston, Logan, McDonough, McHenry, McLean, Macoupin, Madison, Peoria, Perry, Rock Island, St. Clair, Sangamon, Tazewell, Vermillion, Will, and Winnebago). Data for violent deaths that occurred in Pennsylvania include 39 counties that represent 82.2% of the state’s population (Adams, Allegheny, Armstrong, Beaver, Berks, Blair, Bradford, Bucks, Cambria, Carbon, Centre, Chester, Clarion, Clearfield, Clinton, Columbia, Crawford, Dauphin, Delaware, Fayette, Forest, Greene, Indiana, Jefferson, Lackawanna, Lancaster, Lehigh, Luzerne, Monroe, Montgomery, Montour, Northampton, Philadelphia, Schuylkill, Union, Wayne, Westmoreland, Wyoming, and York). Data for violent deaths that occurred in California include 21 counties that represent 54% of the state’s population (Amador, Butte, Fresno, Humboldt, Imperial, Kern, Kings, Lake, Los Angeles, Marin, Mono, Placer, Sacramento, San Benito, San Diego, San Francisco, San Mateo, Shasta, Siskiyou, Ventura, and Yolo). Denominators for the rates for these three states (California, Illinois, and Pennsylvania) represent only the populations of the counties from which the data were collected.
§Percentage is based on the total number of suspects within each age group (i.e., column totals at the bottom of the table).
Includes persons of any race.
** Percentage is based on the number of homicide suspects with a known age and victim-suspect relationship (n = 5,159; aged <18 years = 314; aged 18–24 years = 1,316; aged 25–44 years = 2,463; aged 45–64 years = 864; aged ≥65 years = 202); victim-suspect relationship was unknown for 2,172 suspects. The victim-suspect relationship should be interpreted using the following statement: “The victim is the [insert relationship] of the suspect,” with the exception of the caregiver relationship.
†† Other relative includes other family member (e.g., cousin or uncle), sibling, grandparent, in-law, or grandchild.
§§ Includes adoptive family members (e.g., adopted child), stepfamily members (e.g., stepparent), and foster family members (e.g., foster child).

    Surveillance for Violent Deaths — National Violent Death Reporting System, 39 States, the District of Columbia, and Puerto Rico, 2018: Discussion

    processing....

    Discussion

    Violent deaths affect males and females and persons of all ages, races, and ethnicities. NVDRS data on specific manners of violent death can be used to describe characteristics of and inequities experienced by populations particularly affected by fatal violence. NVDRS data can also be used to identify cross-cutting risk factors for multiple forms of violence. These details increase the knowledge base about the circumstances associated with violence and can assist public health authorities and their partners in developing and guiding effective, data-driven approaches to violence prevention.

    The occurrence of violent death varies greatly across states, the District of Columbia, and Puerto Rico [1]. This report summarizes data on violent deaths that occurred in 2018 in 39 states and the District of Columbia, representing 72.0% of the U.S. population and accounting for 72.9% of violent deaths in the United States in 2018 [1], and Puerto Rico. In 2019, NVDRS expanded data collection to include all 50 states, the District of Columbia, and Puerto Rico, providing more comprehensive, accessible, and actionable violent death information that can be used to guide the development of evidence-based violence prevention efforts at local, regional, state, and national levels. Expanding NVDRS to a nationwide system also contributes to the national prevention initiative Healthy People 2020 objectives to increase the number of states that link data on violent deaths from death certificates, coroner or medical examiner reports, and law enforcement reports at state and local levels and the Healthy People 2030 objectives to reduce the number of suicides, homicides, and firearm-related deaths [12,13].

    Violence is preventable, and reducing violent deaths in communities is possible with evidence-based approaches, such as those outlined in CDC’s technical packages for violence prevention [14]. CDC developed technical packages to assist communities in identifying violence prevention approaches that are based on the best available evidence. The five technical packages describe strategies, approaches, and specific programs, practices, and policies with evidence to reduce the risk for suicide, youth violence, child abuse and neglect, intimate partner violence, and sexual violence. Each technical package considers the multifaceted and interactive effects of different levels of the social ecology, including individual, relationship, family, school, and community factors that influence violence-related outcomes. NVDRS gathers ongoing, systematic, and consistent data on violent deaths that can be used by violence prevention experts within their communities to guide planning and implementation and track outcomes of violence prevention strategies and approaches.

    Suicides

    Suicide Circumstances

    Suicide rates were highest among males and adults aged 45–64 years. Approximately one third of suicide decedents had a history of suicidal thoughts or plans, and approximately one fourth had disclosed their suicidal intent. Mental health problems were the most commonly identified circumstance; however, approximately one half of suicide decedents did not have a known mental health condition at the time of their death. Past suicidal behavior and mental health problems are important risk factors for suicide [15], and these circumstances are well documented as important risk factors to target in suicide prevention [15,16]. Approximately one third of suicide decedents were known to be receiving treatment at the time of death, pointing to a gap between those receiving treatment and those who would likely benefit from it. Multiple factors contribute to the risk for suicide [17], and the findings in this report indicate that intimate partner problems, recent or impending crises, and physical health problems also were common precipitating circumstances. A high prevalence of alcohol use was observed among suicide decedents tested for substances, especially those with BAC ≥0.08g/dL. Alcohol use is a robust predictor of suicidal behavior [18], victimization [19], and interpersonal violence perpetration [20,21]. Intoxication can lead to disinhibition, enhance feelings of hopelessness and depression, and impair judgment, which can lead to impulsive behaviors [16].

    Another factor that might contribute to the risk for suicide is access to lethal means [15]. Similar to rates observed for alcohol and antidepressants, toxicology results for opioids (illicit or prescription) were positive in approximately one fourth of suicide decedents who were tested for these substances. Opioid overdose has been recognized as an epidemic [22]. CDC published the Guideline for Prescribing Opioids for Chronic Pain to provide recommendations for primary care physicians who are prescribing opioids for chronic pain outside of active cancer treatment, palliative care and end-of-life care to improve communication between clinicians and patients about the risks and benefits of opioid therapy for chronic pain, support safer prescribing practices, and reduce the risks associated with long-term opioid therapy including opioid use disorder, overdose, and death [23]. Previous research suggests that chronic pain might be a contributor to suicide; for this reason, these guidelines also aim to ensure that patients receive appropriate care for pain [24]. Building on previous CDC programs focused on opioid overdose and injury prevention, CDC also has implemented comprehensive surveillance and prevention activities through Overdose Data to Action to support state and local health departments in collecting and reporting more timely and complete data on overdose morbidity and mortality and using the data to inform prevention and response efforts [25–27]. Other activities to address the opioid overdose epidemic include expanding naloxone availability and access to treatment with medications for opioid use disorder, enhancing public health and public safety partnerships, and maximizing the ability of health systems to link persons to treatment and harm-reduction services [25–28]. A firearm was the most common method used in suicides. Lethal means, such as firearms, provide limited opportunity for intervention and have high case-fatality rates [15]. Creating protective environments by reducing access to lethal means among persons at-risk can be an effective strategy to prevent suicide [15].

    Racial and Ethnic Inequities in Suicide Rates

    Demographic variations persist in the manner of death from violence-related injuries. Suicides comprise the majority of violent deaths collected in NVDRS and occur at higher rates among non-Hispanic AI/AN and White persons. The findings regarding suicide rates experienced by non-Hispanic AI/AN persons warrant attention to the contextual factors that might contribute to higher rates of suicide, such as barriers to accessing mental health care, exposure to the suicide of a friend or family member as a contributing factor to one’s own death by suicide, and alcohol and substance use [29]. AI/AN persons’ experiences with historical trauma related to the intergenerational, collective, and cumulative impact of colonialism and ongoing inequities including discrimination, disparaging stereotypes, and microaggressions can contribute to risk for suicide [30,31]. Challenges related to suicide, alcohol, and substance use are not inherent to AI/AN culture but should be interpreted within the context of historical racism and ongoing inequities. The heterogeneity among persons and groups that identify as AI/AN also should be acknowledged [29,30].

    Suicide Prevention Strategies

    States participating in NVDRS have used their data to support prevention efforts. NVDRS programs often partner with collaborators to provide data on violent deaths, and those collaborators in turn use the data to guide prevention efforts. For example, Arizona and Wisconsin use their VDRS data to support suicide prevention efforts within their respective states. Arizona VDRS partners with Arizona’s statewide Be Connected initiative to provide customized community-level data on veteran suicide deaths in Arizona. Be Connected directly engages in veteran suicide prevention, including staffing a support line, providing resource matching and navigation, and training for the community [32]. This partnership demonstrates the applied use of NVDRS data for Arizona, and consequently allows for proactive outreach to and engagement with veterans at risk for suicide.

    Wisconsin VDRS used multiple years of data (2013–2017) to identify important risk and protective factors and subsequently develop a comprehensive suicide prevention plan for Wisconsin. Wisconsin VDRS found that during 2013–2017, suicide rates were highest among non-Hispanic White and AI/AN persons [33]. Non-Hispanic groups had higher rates of suicide than the Hispanic population, and nonfatal self-harm injury rates were highest among non-Hispanic Black and AI/AN persons [33]. Rural counties had higher suicide rates compared with urban and suburban counties [33]. In addition, 25% of suicide decedents had a previous suicide attempt, and 20% had a reported job problem, financial problem, or both [33]. These findings demonstrated the impact of suicide in Wisconsin and prompted the development of the Wisconsin Suicide Prevention Plan [33], which is a comprehensive plan designed to increase the effectiveness of suicide prevention efforts in Wisconsin. In addition, to address high rates of suicide among at-risk populations, the plan proposes to expand access to services for mental health and substance use treatment (including physical health care), support innovative ways to expand access to care, including technologies and peer-led or other nonclinical support services, and increase the public’s knowledge of suicides, which includes recognizing warning signs and preparedness to support and respond to persons at risk. This plan highlights the importance of using the best available data; mobilizing coordinated, effective efforts by state agencies, local suicide prevention coalitions, and other partners; facilitating statewide impact of evidence-based and best practices; and monitoring the progress of the prevention plan at the state level, all of which might help to reduce the overall number of suicides in Wisconsin.

    CDC’s suicide prevention technical package describes seven strategies for reducing suicide and suicidal behaviors: 1) strengthen economic supports, 2) strengthen access to and delivery of suicide care, 3) create protective environments, 4) promote connectedness, 5) teach coping and problem-solving skills, 6) identify and support persons at risk, and 7) decrease harms and prevent future risk [14]. These strategies support the goals and objectives of the National Strategy for Suicide Prevention (NSSP), which is a comprehensive national agenda for suicide prevention [34], and the National Action Alliance for Suicide Prevention’s priority to strengthen community-based prevention [35]. NVDRS is relevant to NSSP’s goals of increasing timeliness and usefulness of surveillance systems related to suicide prevention and evaluating outcomes and effectiveness of suicide prevention interventions. The suicide prevention technical package includes examples of specific approaches that communities can implement to advance each strategy. The findings in this report underscore the importance of approaches outlined in the suicide technical package, such as social-emotional learning programs, enhancing parenting skills and family relationships, and treatment for persons at risk for suicide and treatment to prevent reattempts.

    Homicides

    Homicides of Infants and Children

    Infants experienced a high homicide rate, highlighting the need for prioritizing child abuse and neglect prevention and intervention strategies to reduce risk for morbidity and mortality. Child abuse and neglect are often associated with immediate physical injuries, emotional and psychological problems, involvement in risky health behaviors later in life, and a host of broader physical health challenges and long-term health consequences [36].

    CDC’s child abuse and neglect prevention technical package identified the following evidence-based strategies and approaches: 1) strengthening economic supports for families, 2) changing social norms to support parents and positive parenting, 3) providing quality care and education early in life, 4) enhancing parenting skills to promote healthy child development, and 5) intervening to decrease harms and prevent future risk [36]. Child abuse and neglect are preventable, and the specific approaches described in the technical package can help create safe, stable, and nurturing relationships and environments [37] to prevent homicides of infants and children as well as nonfatal child maltreatment.

    Racial and Ethnic Inequities in Homicide Rates

    Racial and ethnic minority groups experience inequitable rates of violent injury and homicide, particularly among youths and young adult males [38]. In the United States, homicide rates were highest among non-Hispanic Black and AI/AN persons. In Puerto Rico, where 95.1% of homicide victims were Hispanic, the homicide rate was more than double the suicide rate. Male homicide victims in Puerto Rico were predominantly Hispanic (94.8%) and experienced homicide rates similar to and even exceeding the homicide rates experienced by non-Hispanic Black, non-Hispanic AI/AN, and Hispanic males in the United States. Racial and ethnic inequities in exposure to violence are pervasive and persistent, and the elimination of these inequities should be prioritized [38]. Racial and ethnic minority groups are disproportionately exposed to systemic inequities such as residential segregation, concentrated disadvantage, stress from experiencing racism, limited access to the best educational and employment opportunities, and other conditions that increase the risk for experiencing violence [38–40]. For example, homicide rates for males in Puerto Rico have been attributed, in part, to persons living in communities that have been marginalized and the socioeconomic incentives of being involved in illegal means of income that are associated with high risks for violence [41]. Racial and ethnic minority youths often live in communities with concentrated poverty, stressed economies, residential instability, neighborhood disorganization, and low community cohesion and informal controls [35,36]. These conditions are associated with violence and violence-related injuries [39]. By addressing the structural, societal, and community-level contexts that serve as risk factors for violence, prevention efforts can have broad and sustained effects [3,41,42].

    NVDRS programs have used their local data to examine violence-related disparities in their states. For example, the Illinois VDRS used 2016–2017 Illinois VDRS data to examine the intersection of homicide and poverty at the county-level and found a relation between homicide and poverty in two thirds of the counties that were examined [43]. Similarly, Illinois VDRS examined firearm-related homicide rates among non-Hispanic Black males aged 15–19 years in Chicago during 2013–2017 and found that the 2017 firearm-related homicide rate among Black males in Chicago aged 15–19 years was 74% higher than that in 2013 [44]. During 2013–2017, non-Hispanic Black males in Chicago aged 15–19 years had an increased risk for firearm-related homicide compared with all persons in the United States and Chicago in this age group. Although firearm-related homicide risk for non-Hispanic Black males aged 15–19 years fluctuated during 2013–2017, in 2017, non-Hispanic Black males aged 15–19 years in Chicago were 13.7 times more likely to be victims of firearm-related homicide compared with non-Black males in this age group [44]. These findings indicate increasing disparities between young non-Hispanic Black males in Chicago and all other young males in the United States. In conjunction with other data sources, NVDRS data can help states identify and target salient neighborhood- and community-level factors related to violence, which can contribute to greater population-level decreases in violence through the reduction and elimination of systemic inequities [45]. CDC’s youth violence prevention technical package outlines several community- and societal-level programs and approaches [14], such as Baltimore’s Safe Streets [46], Crime Prevention Through Environmental Design [47], business improvement districts [48,49], and policies such as the Earned Income Tax Credit (EITC) [50,51]. For example, enhancing household financial security through tax credits, such as the EITC, can help families raise their income while incentivizing work or counterbalancing the costs of child-rearing and help create home environments that encourage healthy development [50,51]. Evaluations of these programs and policies have confirmed the value of using these types of approaches to reduce the risk for violence and promote protective community environments [14]. Evidence also suggests that these approaches and other universal policies that focus on general community improvements can have a substantial impact on decreasing racial and ethnic inequities in violence [39].

    Intimate Partner Violence–Related Homicide

    Homicides among males were most often preceded by an argument or conflict or precipitated by another crime, and the suspect was most often an acquaintance or friend. In contrast, approximately 45% of homicides among females were related to intimate partner violence, and a current or former intimate partner was identified as the suspect for approximately one half of female homicide victims with known suspects. These findings were consistent with another NVDRS report that highlighted the differential impact of intimate partner violence–related homicides among young and racial and ethnic minority women [52]. Intimate partner violence affects millions of persons in the United States each year [53]. Estimates from the 2015 National Intimate Partner and Sexual Violence Survey indicated that approximately 80 million persons in the United States have experienced intimate partner violence (e.g., contact sexual violence, physical violence, and stalking by an intimate partner) at some point in their lives, and approximately 12 million persons experienced intimate partner violence in the previous 12 months [53].

    Although approximately one half (49.2%) of homicides involving intimate partner violence were perpetrated by suspects aged 25–44 years, among suspects aged 45–64 years and those aged ≥65 years, the victim was most often a current or former intimate partner. For example, suspects aged ≥65 years accounted for only 8.5% of suspects involved in intimate partner violence–related homicides overall; however, 58.2% of suspects within this age group were involved in intimate partner violence–related homicides. Studies examining older adult perpetration of intimate partner homicide have highlighted the potential influence of factors such as relationship discord, impending separation, caregiver-related stressors, and physical and mental health problems have on intimate partner violence [54,55]. Intimate partner violence–related homicides warrant further research to determine the contextual factors and characteristics of these fatal incidents and how these contextual factors might vary by age group.

    NVDRS programs have used their data to examine intimate partner violence–related deaths to support prevention efforts [56]. Data from the South Carolina VDRS were used to examine intimate partner homicides that occurred in South Carolina during 2017 [56]. South Carolina VDRS found that 12% of all homicides that occurred in 2017 were intimate partner violence related, with females accounting for 52% of intimate partner violence–related homicide victims. In addition, approximately one in three intimate partner violence–related homicides occurred during an argument, and an argument contributed to the death of 44% of males and 41% of female homicide victims in South Carolina in 2017. These data were shared with domestic violence prevention collaborators in South Carolina to bolster their efforts in reducing intimate partner violence–related deaths.

    CDC’s intimate partner violence prevention technical package outlines several strategies for programs and policies to prevent intimate partner violence and to decrease harms [57]. Strategies and approaches to prevent and reduce intimate partner violence might occur across different levels of the social ecology, such as engaging men and boys as allies [57,58]; disrupting developmental pathways toward intimate partner violence; creating protective school, workplace, and neighborhood environments [57]; teaching youths about safe and healthy relationships [57,58]; empowering bystanders; and strengthening economic supports to families [57]. Prevention efforts can help change harmful gender norms that condone violence and the societal conditions that serve to maintain those norms [57,59].

    Homicide Suspects

    Most homicide suspects with known age were males aged 18–44 years, which is consistent with previous studies describing homicide suspect demographics [60]. Most suspects were accused of fatally injuring an acquaintance or friend, or a current or former intimate partner or spouse. The data provide more insight into the potential context of homicides when victim-suspect relationships are examined by age group. For example, among persons aged ≤24 years, suspects were most often accused of fatally injuring an acquaintance or friend, stranger, or other person whom they knew but who was not a relative. For suspects aged ≥24 years, increasingly larger proportions of current or former intimate partners or spouses were reflected in the victim-suspect relationship than proportions of other types of victim-suspect relationships. Attempting suicide after a homicide was another prominent contextual factor among those aged ≥45 years. The considerable prevalence of current or former intimate partners as victims and attempted suicide after the homicide are consistent with a previous study that identified having a history of intimate partner conflict as common among homicide-suicide incidents [60].

    A mental health problem was noted as a direct contributing factor to the homicide for <5% of suspects, which challenges public perceptions of associations between mental health problems and violent behavior [61]. Exploring contexts in which mental health problems are a contributing factor and dispelling stigma that can lead to discrimination and present barriers to life opportunities for those living with persistent mental health challenges are important [61]. Approximately 12% of suspects were noted as having contact with law enforcement within the 12 months before the homicide. Prior contact with law enforcement included instances in which the police were called, regardless of whether an arrest was made [6]. This finding warrants future research to determine the extent and nature of prior law enforcement contact and the potential opportunity for law enforcement to disrupt pathways toward escalating forms of violence, including homicide.

    Additional research to examine how incident contexts and risk and protective factors for homicide perpetration vary across age groups can help guide approaches to violence prevention and identify potential intervention points for reducing onset or progression of violence within relationships and communities. Individual, relationship, and community-level interventions that prevent initial violence perpetration or escalating violence are an important part of a comprehensive approach to violence prevention as described in CDC’s technical packages for violence prevention.

    Legal Intervention Deaths

    NVDRS collects more complete information than other data sources on legal intervention deaths [62]. The rate of legal intervention death was highest among non-Hispanic AI/AN persons, and the rate among non-Hispanic Black males was 2.6 times that of their non-Hispanic White male counterparts, a finding consistent with previous studies [63,64]. Racial and ethnic inequities in fatal police shootings have been examined in violence literature [63,65–67] and have been attributed to factors such as increased police contact caused by more traffic stops, a higher presence of law enforcement in racial and ethnic minority communities, and race-based bias and perceptions of threat. More analyses are needed to increase knowledge about the magnitude and circumstances of these deaths and for developing appropriate prevention strategies and monitoring their effectiveness. Other studies have provided a review of strategies for decreasing legal intervention deaths, such as increasing training in conflict de-escalation and tactical disengagement, and training to reduce potential bias in law enforcement officers’ responses to suspects [63,65]. After a number of high-profile legal intervention deaths including the murder of George Floyd in 2020, several policy changes have been proposed to reduce police violence and enhance relationships between law enforcement and the communities they serve. These proposals include strengthening and monitoring local police use-of-force policies, recruiting a diverse police force, and training officers in appropriate and safe interactions with the community [68].

    A unique strength of the NVDRS surveillance system is the ability to capture data on suspects, including characteristics of law enforcement officers involved in legal intervention deaths [2,63]. Although 49.4% of 2018 NVDRS legal intervention incidents had unknown demographic and circumstance information for the officers involved, the available information provided some insight into the officers involved in violent deaths that occurred in the line of duty. When demographic information was known, law enforcement officers involved in legal intervention deaths were most frequently non-Hispanic White males aged 25–44 years. The demographics of law enforcement officers involved in legal intervention deaths are consistent with demographics of the U.S. police force, which tends to be predominantly comprised of non-Hispanic White males [69]. Although not examined in the current report, a previous study examining characteristics of officers involved in legal intervention deaths found associations between officer use of lethal force and demographic characteristics such as race, age, sex, and education as well as previous use of force [70]. Given previous findings on officers involved in legal intervention deaths and the importance of NVDRS for capturing information on legal intervention deaths, researchers have called on NVDRS to increase the completeness of demographic information on officers involved in these deaths [63,70].

    Unintentional Firearm Deaths

    NVDRS has been recognized as a reliable source of data on unintentional firearm deaths [71] and for its ability to provide details about victims and shooters [72]. Approximately one half of unintentional firearm deaths were self-inflicted; however, approximately one third were known to have been inflicted by another person. Most of these deaths occurred while playing with a gun, accidentally pulling the trigger, or thinking the gun was unloaded, which are of concern, particularly among children [73]; these findings highlight the importance of safe storage practices and education about safe handling of firearms [74].
