Suicide is the 12th-leading cause of death in the United States. It is the second-leading cause of death for Americans ages 10-14 and 24-34, the third-leading cause for Americans ages 15-24 and the fourth-leading cause among Americans ages 25-44. In 2021, an estimated 3.5 million people planned a suicide, 1.7 million attempted suicide and 48,183 died by suicide. More than half of all suicides that year involved firearms and there were almost twice as many suicide deaths as homicide deaths.
When someone dies by suicide, as with any cause of death, the loss is felt by many people. The ripples of loss spread from close family and friends to community members, acquaintances and even people the deceased did not know. All of those exposed to the loss may experience different levels of grief and trauma.
Mental health and substance use disorders are the most significant risk factors for suicidal behaviors. In addition, environmental factors such as stressful life events and access to lethal means such as firearms or drugs may increase the risk of suicide. Previous suicide attempts and a family history of suicide are also important risk factors.
In 2020 suicide cost the U.S. $255.6 million in medical expenses and $475.7 billion in loss of life.
According to America’s Health Rankings data, the rate of suicide is higher among:
Strategies to reduce suicide include:
The Suicide Prevention Resource Center has detailed information on implementing effective suicide prevention in schools, universities, emergency departments, American Indian/Alaska Native communities and other organizations that serve populations with high suicide risk. The 988 Suicide & Crisis Lifeline provides free, confidential support for people in distress 24/7 anywhere in the United States. Their website offers additional forms of crisis support, and the previous National Suicide Prevention Lifeline number (1-800-273-TALK(8255)) is still active and usable.
Reducing the suicide rate is a Healthy People 2030 leading health indicator.
