About one-third of people who die by suicide leave a note. The most comprehensive U.S. data, drawn from nearly 272,000 suicide deaths recorded between 2003 and 2020 in the CDC’s National Violent Death Reporting System, puts the figure at 32.1%. That means roughly two out of three people who die by suicide leave no written explanation behind.
How Rates Differ by Gender
Women who die by suicide are more likely to leave a note than men. In that same dataset of over 270,000 deaths, 38.6% of female decedents left a note compared to 30.2% of male decedents. The reasons behind this gap aren’t fully settled, but it aligns with broader patterns: women are generally more likely to communicate emotional states and relational concerns in writing. When researchers have compared the actual content of notes left by men and women, the themes are largely similar, though men tend to reference specific triggering events more often.
Why Most People Don’t Leave a Note
The absence of a note is far more common than its presence, and there are several reasons for this. Many suicides happen impulsively, during a crisis that unfolds in minutes rather than hours. A person in acute distress may not have the time, clarity, or desire to sit down and write. Alcohol and drugs, which are involved in a significant portion of suicide deaths, further reduce the likelihood of planning a written message.
Some people may feel there’s nothing left to say, or that words can’t capture what they’re experiencing. Others may not want to burden the people they’re leaving behind. Depression itself narrows thinking in ways that can make the act of writing feel pointless or overwhelming. Researchers have found that people with depression who do leave notes are more likely to express difficulty forming close connections and to show rigid, all-or-nothing thinking in their writing.
There’s also no social script that says you’re “supposed to” leave one. Despite how prominently suicide notes appear in movies and television, the reality is that most people simply don’t write them.
What Notes Typically Contain
When notes are left, they tend to fall into a few broad categories. Some are apologetic, expressing regret or sorrow toward loved ones. Some are instructional, covering practical matters like finances, passwords, or funeral wishes. Others attempt to explain the decision, describing emotional pain, hopelessness, or feeling like a burden. A smaller number express anger or blame toward specific people or circumstances.
Many notes contain more than one of these themes. A single note might apologize to a spouse, leave instructions about the house, and try to articulate why the person felt they had no other option. Researchers studying 45 suicide notes alongside coroner’s reports found that the psychological themes in the notes often matched clinical indicators visible in the person’s broader history, suggesting the notes tend to be honest reflections of the person’s mental state rather than performative gestures.
One detail that surprises many people: the word “sorry” appears far less often than expected. In one study of notes from both men and women, only 5% of notes from each group actually contained an apology using that word.
Why the Absence of a Note Matters
The low rate of note-leaving creates a real problem for death investigators. Some medical examiners and coroners have historically required a suicide note to classify a death as a suicide. The CDC has pushed back against this standard, noting that requiring a note effectively guarantees that a large number of actual suicides get classified as something else, typically “undetermined” deaths. As the CDC has stated directly: the absence of evidence of intent is not evidence of absence of intent.
This means official suicide statistics likely undercount the true number of deaths. When a note is present, the classification is straightforward. When it isn’t, the determination depends on other evidence: the method used, the person’s mental health history, recent life events, statements made to others, and the circumstances at the scene. Jurisdictions that rely too heavily on notes as proof of intent will systematically miss cases, particularly among demographics less likely to leave written messages.
What This Means for Survivors
For families and friends left behind, the absence of a note can be one of the most painful aspects of a suicide loss. It’s natural to want an explanation, and when none exists, people often fill the silence with guilt or speculation. Understanding that most people don’t leave notes, and that the reasons have more to do with the nature of crisis and mental illness than with any message to survivors, can help reframe that absence. A missing note doesn’t mean the person didn’t care about the people in their life. It means they were in a state where writing wasn’t possible, or wasn’t something that occurred to them in their final moments.
