Definitions

Suicide is a major public health concern. Suicide is among the leading causes of death in the United States. Based on recent nationwide surveys, suicide in some populations is on the rise.

  • Suicide is defined as death caused by self-directed injurious behavior with intent to die as a result of the behavior.
  • A suicide attempt is a non-fatal, self-directed, potentially injurious behavior with intent to die as a result of the behavior. A suicide attempt might not result in injury.
  • Suicidal ideation refers to thinking about, considering, or planning suicide.

Additional information about suicide can be found on the NIMH health topics page on Suicide Prevention.

Suicide is a Leading Cause of Death in the United States

  • According to the Centers for Disease Control and Prevention (CDC) WISQARS Leading Causes of Death Reports, in 2017:
    • Suicide was the tenth leading cause of death overall in the United States, claiming the lives of over 47,000 people.
    • Suicide was the second leading cause of death among individuals between the ages of 10 and 34, and the fourth leading cause of death among individuals between the ages of 35 and 54.
    • There were more than twice as many suicides (47,173) in the United States as there were homicides (19,510).

Table 1 shows the ten leading causes of death in the United States, and the number of deaths attributed to each cause. Data are shown for all ages and select age groups where suicide was one of the leading ten causes of death in 2017. The data are based on death certificate information compiled by the CDC.

Suicide Rates

Data in Figure 1, Figure 2, and Figure 3 are courtesy of the CDC Fatal Injury Data Visualization.

Trends over Time

  • Suicide rate is based on the number of people who have died by suicide per 100,000 population. Because changes in population size are taken into account, rates allow for comparisons from one year to the next.
  • Figure 1 shows the age-adjusted suicide rates in the United States for each year from 2001 through 2017 for the total population, and for males and females presented separately.
    • During that 16-year period, the total suicide rate increased 31% from 10.7 to 14.0 per 100,000.
    • The suicide rate among males remained nearly four times higher (22.4 per 100,000 in 2017) than among females (6.1 per 100,000 in 2017).

Figure 1

2015 13.3 6.0 21.0
2016 13.4 6.0 21.3
2017 14.0 6.1 22.4

Demographics

  • Because suicide rates take population size into account, they can be a useful tool for understanding the relative proportion of people affected within different demographic groups.
  • Figure 2 shows the crude rates of suicide within sex and age categories in 2017.
    • Among females, the suicide rate was highest for those aged 45-54 (10.0 per 100,000).
    • Among males, the suicide rate was highest for those aged 65 and older (31.0 per 100,000). 

Figure 2

Suicide Rates by Age (per 100,000)
Age Female Male
10–14 1.0 3.0
15–24 5.0 22.0
25–34 7.0 27.0
35–44 8.0 27.0
45–54 10.0 30.0
55–64 8.0 29.0
65+ 5.0 31.0
  • Figure 3 shows the rates of suicide for race/ethnicity groups in 2017. The rates of suicide were highest for American Indian/Alaska Native, Non-Hispanic males (33.6 per 100,000) and females (11.0 per 100,000), followed by White, Non-Hispanic males (28.2 per 100,000) and females (7.9 per 100,000).

Suicide Rates by State

  • Suicide rates are not the same from state to state. Based on data from the CDC WISQARS Fatal Injury Mapping tool, Figure 4 shows a map of the United States with each state’s age-adjusted average suicide rate from 2008 to 2014 indicated by color.

Suicide by Method

Data in Table 2 and Figure 5 are courtesy of the CDC WISQARS Leading Causes of Death Reports.

Number of Suicide Deaths by Method

  • Table 2 includes information on the total number of suicides for the most common methods.
  • In 2017, firearms were the most common method used in suicide deaths in the United States, accounting for almost half of all suicide deaths (23,854).

Total 47,173
Firearm 23,854
Suffocation 13,075
Poisoning 6,554
Other 3,690

Percent of Suicide Deaths by Method

  • Figure 5 shows the percentages of suicide deaths by method among males and females in 2017. Among males, the most common method of suicide was firearm (56.0%). Among females, the most common methods of suicide were poisoning (31.4%) and firearm (31.2%).

Female 9.6 27.9 31.4 31.2
Male 7.3 27.7 9.0 56.0

Cost of Suicide Deaths

  • In addition to the emotional loss associated with suicide, there is also an economic loss as the burden of suicide falls most heavily on adults of working age.
    • Figure 6 shows data from a 2013 CDC report on the medical and work-loss costs of fatal injury by intent in the United States.
    • Suicide accounted for $50.8 billion (24%) of the fatal injury cost.

Suicidal Thoughts and Behaviors Among U.S. Adults

Data in Figure 7, Figure 8, and Figure 9 are based on data from the 2017 National Survey on Drug Use and Health (NSDUH)1 by the Substance Abuse and Mental Health Services Administration (SAMHSA).

  • Figure 7 shows that 4.3% of adults age 18 and older in the United States had thoughts about suicide in 2017.
    • Among adults across all age groups, the prevalence of serious suicidal thoughts was highest among adults aged 18-25 (10.5%).
    • Among adults reporting race/ethnicity, the prevalence of serious suicidal thoughts was highest among adults reporting two or more races (8.9%).

  • Figure 8 shows that 0.6% of adults age 18 and older in the United States attempted suicide in 2017.
    • Among adults across all age groups, the prevalence of suicide attempts in the past year was highest among adults aged 18-25 (1.9%).
    • Among adults reporting race/ethnicity, the prevalence of suicide attempts in the past year was highest among adults reporting two or more races (1.3%).

  • Figure 9 shows that in 2017, 10.6 million adults aged 18 or older reported having serious thoughts about trying to kill themselves, and 1.4 million adults made a non-fatal suicide attempt during the past year. Among those adults who attempted suicide, 1.2 million reported making suicide plans.

Statistical Methods and Measurement Caveats

National Survey on Drug Use and Health (NSDUH)

Population:

  • The survey participants are from a civilian, non-institutionalized population aged 18 years old or older residing within the United States. NSDUH does not ask adolescents aged 12 to 17 about suicidal thoughts and behavior.
  • The survey covers residents of households (persons living in houses/townhouses, apartments, condominiums; civilians living in housing on military bases, etc.) and persons in non-institutional group quarters (e.g., shelters, rooming/boarding houses, college dormitories, migratory workers' camps, and halfway houses).
  • The survey does not cover persons who, for the entire year, had no fixed address (e.g., homeless and/or transient persons not in shelters); were on active military duty; or who resided in institutional group quarters (e.g., correctional facilities, nursing homes, mental institutions, long-term hospitals).

Survey Non-response:

  • In 2017, 32.9% of the NSDUH adult sample did not complete the interview.
  • Reasons for non-response to interviewing include: refusal to participate (23.1%); respondent unavailable or never at home (5.0%); and various other reasons, such as physical/mental incompetence or language barriers (4.8%).
  • People with suicidal behavior may disproportionately fall into these non-response categories. While NSDUH weighting includes non-response adjustments to reduce bias, these adjustments may not fully account for differential non-response by suicide behavior status.
  • Please see the 2017 National Survey on Drug Use and Health Methodological Summary and Definitions report for further information on how these data were collected and calculated.
