Suicidal thoughts are far more common than most people realize. In the United States alone, roughly 12.8 million adults seriously think about suicide in a given year. That’s about 1 in 20 adults, and the true number is likely higher because more than half of people who experience these thoughts never tell anyone.
How Common Suicidal Thoughts Are
The CDC’s most recent data shows that 12.8 million American adults seriously thought about suicide, 3.7 million made a plan, and 1.5 million attempted suicide. Put another way, for every person who attempts suicide, about seven others are experiencing suicidal thoughts without acting on them. About two thirds of people with suicidal ideation never make an attempt, and a population-based study found that only 7% of people with suicidal thoughts attempted suicide within the following two years.
These numbers only capture what people report. Research consistently finds that over 50% of people experiencing suicidal thoughts don’t disclose them to anyone. In one study, 31% of therapy patients admitted they had lied to a therapist about suicidal ideation in the past, and 10% had lied about a previous attempt. Among psychiatric patients specifically, roughly half withheld information about suicidal thoughts during intake assessments. In a Veterans Affairs study, 72% of patients who died by suicide had not reported suicidal ideation on their most recent screening questionnaire.
The Spectrum From Fleeting to Persistent
Not all suicidal thoughts look the same. They exist on a wide spectrum, from passive wishes (“I wish I weren’t here” or “it would be easier if I didn’t wake up”) to active ideation with a specific plan and intent to act. Passive thoughts of death are significantly more common than active planning. Of the 12.8 million adults who seriously think about suicide each year, roughly 3.7 million progress to making a plan.
The duration of suicidal episodes can be surprisingly brief. Research on people who attempted suicide found that the median time from the onset of suicidal thinking to action was just 30 minutes. More than half had a “suicidal process” lasting under 30 minutes, and about 30% described a window of 5 minutes or less. Other research has found the decision-to-action gap was 10 minutes or less in about half of attempters. This is important because it means suicidal crises are often short-lived and intense rather than slow and deliberate. For many people, getting through a brief period of acute distress is the difference between life and death.
That said, some people experience chronic suicidal ideation that persists for weeks, months, or years at varying levels of intensity. The frequency and duration of episodes varies enormously from person to person, and clinicians assess onset, frequency, intensity, triggers, and how much control a person feels over the thoughts.
Who Thinks About Suicide Most Often
Suicide rates in 2023 were highest among adults 85 and older (22.7 per 100,000), followed by those 75 to 84 (19.4) and 35 to 44 (19.2). The 45-to-54 age group (18.9), 55-to-64 range (18.7), and 25-to-34 range (18.6) all cluster closely together. Younger adults 15 to 24 had a rate of 13.5 per 100,000, and children 10 to 14 had the lowest rate at 2.3.
The pattern for suicidal thoughts doesn’t perfectly mirror the pattern for deaths. Younger people tend to report higher rates of suicidal ideation but lower rates of death by suicide, while older adults, particularly men over 75, report ideation less frequently but die by suicide at the highest rates. This disconnect partly reflects differences in method lethality and partly reflects the tendency of older adults to disclose less.
Certain groups carry disproportionate risk. Among U.S. military veterans, 7.3% report current suicidal ideation, and more than 60% of those veterans are not receiving any mental health treatment. High-stress occupations, social isolation, chronic pain, and previous trauma all increase the likelihood of recurring suicidal thoughts.
The Rise During and After COVID-19
Suicidal ideation increased measurably during the COVID-19 pandemic. A systematic review of over 50 studies found that the prevalence of suicidal thoughts rose by about 14% in the general population and 13% in clinical settings compared to pre-pandemic levels. Both increases were statistically significant. Suicide attempts also trended upward, though the overall suicide death rate remained relatively stable during this period. The factors driving the increase, including isolation, economic stress, disrupted access to care, and grief, have not fully resolved.
What These Numbers Mean in Practice
If you’ve had thoughts about suicide, you’re in the company of millions of people who have experienced the same thing. The presence of suicidal thoughts does not mean you will act on them. Most people who think about suicide do not attempt it, and the intensity of these thoughts typically fluctuates rather than remaining constant.
What matters most is recognizing patterns. Thoughts that become more frequent, more specific (shifting from “I don’t want to be here” to a concrete method or timeline), or harder to control represent a meaningful change. The brevity of many suicidal crises also means that creating even small barriers, like distance from means or contact with another person, can be enough to survive the moment when risk is highest.
The fact that more than half of people with suicidal thoughts never disclose them to anyone suggests that the 12.8 million figure substantially undercounts reality. Many people carry these thoughts privately, assuming they’re alone in the experience or fearing judgment. The data makes clear they are not alone, and that having suicidal thoughts is a recognized, common human experience with effective paths to relief.
