More than 720,000 people die by suicide every year worldwide. In the United States alone, 49,316 people died by suicide in 2023, making it one of the top eight leading causes of death for people ages 10 to 64. These numbers, while staggering, likely undercount the true toll.
Global Numbers
The World Health Organization estimates that 727,000 people take their own life each year. That works out to roughly one death every 43 seconds. Suicide affects every region and income level, though rates vary significantly between countries depending on factors like access to mental health care, cultural attitudes, and the availability of common means.
The United Nations has set a target under its Sustainable Development Goals to reduce premature mortality from noncommunicable diseases, including suicide, by one third by 2030. Progress toward that goal has been uneven.
Suicide in the United States
The most recent U.S. data tells two slightly different stories depending on the reporting year. The CDC’s 2024 mortality data (reflecting deaths recorded through its vital statistics system) counted 48,824 suicide deaths at a rate of 14.4 per 100,000 people. A separate CDC tally for the 2023 calendar year recorded 49,316 deaths at an age-adjusted rate of 14.1 per 100,000. Either way, suicide consistently claims close to 50,000 American lives per year.
Among younger Americans, the picture is especially stark. Suicide was the second leading cause of death for people ages 10 to 34 in 2023. For the broader range of 10 to 64, it ranked among the top eight causes. These rankings place suicide ahead of many conditions that receive far more public attention and research funding.
The Numbers Are Almost Certainly Too Low
Suicide is one of the hardest causes of death to certify accurately. A death may be classified as accidental, undetermined, or attributed to another cause when evidence is ambiguous or when families and officials face social or legal pressures to avoid a suicide determination. The CDC has acknowledged that the true incidence of suicide may be underestimated by 10% to 50%. If the higher end of that range is accurate, the real global figure could exceed one million deaths per year.
Common scenarios for misclassification include single-car crashes, drownings, drug overdoses, and falls where intent is difficult to establish after the fact. Coroner and medical examiner systems vary widely in their training, resources, and criteria for ruling a death a suicide, which introduces inconsistency even within a single country.
Deaths Versus Attempts
For every person who dies by suicide, many more attempt it and survive. Estimates of the ratio vary, but it is widely cited that there are roughly 25 nonfatal attempts for every completed suicide in the United States. That would put the annual number of attempts in the U.S. above one million. Globally, the figure is far higher but nearly impossible to pin down because most attempts never result in hospital visits or official records.
The gap between attempts and deaths is shaped heavily by the method used. Access to more lethal means, particularly firearms, significantly increases the likelihood that an attempt will be fatal. This is one reason public health strategies increasingly focus on reducing access to lethal means during periods of crisis, since many suicidal crises are temporary and survivable if the most dangerous options are not immediately available.
Who Is Most Affected
Men die by suicide at substantially higher rates than women in nearly every country. In the United States, men account for roughly four out of every five suicide deaths. Women, however, attempt suicide more often. This disparity is largely explained by differences in method: men are more likely to use firearms, which are the most lethal means available.
Age patterns matter too. While suicide among young people draws significant media attention, and rightly so given its ranking as a leading cause of death in that age group, older adults historically have some of the highest suicide rates per capita. Men over 75 are at particularly elevated risk in many countries, a fact that often goes unrecognized. Middle-aged adults, especially men in their 40s and 50s, also carry disproportionately high rates in the United States.
What Drives These Numbers
Suicide is rarely caused by a single factor. The most common contributors include mental health conditions like depression and substance use disorders, but also financial hardship, relationship loss, chronic pain, social isolation, and access to lethal means. Many people who die by suicide were not receiving mental health treatment at the time of their death, which points to gaps in both access and early identification.
At a population level, suicide rates tend to rise during economic downturns and periods of social disruption. They also vary by occupation, with certain fields like construction, mining, agriculture, and veterinary medicine showing consistently elevated rates. Rural communities generally have higher rates than urban ones, partly due to greater access to firearms and fewer mental health providers.
