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 2020:
  • Suicide was the twelfth leading cause of death overall in the United States, claiming the lives of over 45,900 people.
  • Suicide was the second leading cause of death among individuals between the ages of 10-14 and 25-34 , the third leading cause of death among individuals between the ages of 15-24, and the fourth leading cause of death among individuals between the ages of 35 and 44.
  • There were nearly two times as many suicides (45,979) in the United States as there were homicides (24,576).

Table 1 shows the twelve 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 twelve causes of death in 2020. The data are based on death certificate information compiled by the CDC.

*Unstable values

Note: In 2019, suicide was the 10th leading cause of death (47,511 suicide deaths). In 2020, liver disease and COVID-19 surpassed suicide as leading causes of death, but suicide deaths decreased compared to 2019 totals (45,979 suicide deaths). Suicide is not among the twelve leading causes of death among children in the 0-4 year age group nor in adults in the age group 65 years and older (data not shown).

Suicide Rates

Data in Figure 1 and Figure 2 are courtesy of the CDC ’s National Center for Health Statistics (NCHS Data Brief No. 433, March 2022).

Trends over Time

• Suicide rates are based on the number of people who have died by suicide per 100,000 population. When comparing rates from one year to another year, ‘age-adjusted’ rates allow for differences in population age distributions and changes in population size over time to be taken into account.
• Figure 1 shows age-adjusted suicide rates in the United States for each year from 2000 through 2020 for the total population, and for males and females separately.
  • The total age-adjusted suicide rate in the United States increased 35.2% from 10.4 per 100,000 in 2000 to 14.2 per 100,000 in 2018, before declining to 13.9 per 100,000 in 2019 and declining again to 13.5 per 100,000 in 2020.
  • In 2020, the suicide rate among males was 4 times higher (22.0 per 100,000) than among females (5.5 per 100,000).

Number of Suicide Deaths by Method

• Table 2 includes information on the total number of suicides for the most common methods.
• In 2020, firearms were the most common method used in suicide deaths in the United States, accounting for over half of all suicide deaths (24,292).

Statistical Methods and Measurement Caveats

National Survey on Drug Use and Health (NSDUH)

Population:

• NSDUH participants are representative of the civilian, non-institutionalized population aged 12 years old or older residing within the United States. Only adults 18 years and older are asked 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).
• Sex (i.e., male and female) was recorded by the interviewer.

Interview Response and Completion:

• In 2020, 37.2% of the NSDUH adult sample did not complete the interview.
• Reasons for non-response to interviewing include: refusal to participate (10.7%); respondent unavailable or never at home (22.6%); and various other reasons, such as physical/mental incompetence or language barriers (3.9%).
• 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.

Data Suppression:

• For some groups, data are not reported due to low precision. Data may be suppressed in the above charts if the data do not meet acceptable ranges for prevalence estimates, standard error estimates, and sample size.

Background on the 2020 NSDUH and the COVID-19 Pandemic:

• Data collection methods for the 2020 NSDUH changed in several ways because of the COVID-19 pandemic: In-person data collection was suspended in all areas in mid-March 2020. No data were collected in Quarter 2, and only a small amount of data were collected in Quarter 3. In-person data collection resumed in limited areas in Quarter 4. A new web mode for data collection was offered in all other areas, resulting in 93 percent of Quarter 4 interviews being completed via the web.
• These changes to 2020 NSDUH data collection affected imputation procedures, weighting procedures, presentation of the data, and analysis and interpretation of the data. Given these changes, interpretation of the 2020 NSDUH data must be made with caution.
• New questions were added to the Quarter 4 questionnaire that were relevant to the COVID-19 pandemic.

Please see the 2020 National Survey on Drug Use and Health Methodological Summary and Definitions report for further information on how these data were collected and calculated.
