Editor’s note: This lesson discusses suicide and suicidal thoughts. Educators should consider students’ age, circumstances and readiness before beginning a classroom discussion and should familiarize themselves with their school or district’s mental health and crisis-response protocols. Anyone in the United States who is experiencing emotional distress or a suicidal crisis can call or text 988 to reach the Suicide & Crisis Lifeline. Support is free and available 24/7.
Introduction
Suicide is a tricky subject to talk about. For years, some conversations about suicide prevention emphasized avoiding discussion out of concern about “suicide contagion”—the documented phenomenon in which certain kinds of exposure, particularly sensationalized or unsafe portrayals, can contribute to suicidal behavior.
But that concern sometimes became conflated with a different fear: that simply talking openly about suicide, or asking someone whether they are considering it, could put the idea in their head. Research does not support that fear. The National Institute of Mental Health (NIMH) says asking directly about suicidal thoughts does not cause or increase them.
At the same time, the word itself became censored or suppressed in some corners of the internet. Young people adapted, using terms such as “unalive” when discussing suicide and death on social media. Researchers have described this phenomenon as “algospeak”—language that users develop in an attempt to avoid platform moderation or algorithmic penalties.
So where does that leave educators and other trusted adults when they hear young people discussing thoughts of death or self-harm?
Often, it is more complex than familiar tropes and portrayals of a teacher or staff member noticing a previously energetic young person becoming more withdrawn or a coach overhearing an athlete say everyone would be “better off” without them. Those signs can matter, but suicide rarely results from one circumstance, and young people's distress exists within a much larger social environment.
Young people today are coming of age amid concerns about climate change, economic insecurity, violence, discrimination, loneliness, social media and uncertainty about the future. Those pressures should not be treated as simple explanations for suicide; most young people who experience them will never attempt suicide, but research increasingly suggests that the conditions in which people live, learn and grow can shape mental health and suicide risk.
Each September, National Suicide Prevention Month and National Suicide Prevention Week focus attention on this difficult but critical public health challenge. For educators, that means becoming more comfortable with the language young people actually use, understanding the pressures they may be carrying, and knowing when and how to help connect a student with support.
Youth Mental Health and Suicide Risk: What the Data Shows
The numbers remain concerning.
According to the Centers for Disease Control and Prevention’s 2023 Youth Risk Behavior Survey, 20.4 percent of U.S. high school students seriously considered attempting suicide during the previous year, while 9.5 percent reported attempting suicide.
At the same time, the data requires some nuance. Several measures of poor mental health and suicidal thoughts and behaviors improved between 2021 and 2023, even as large disparities remained among different groups of students.
There is also no single explanation for why a young person thinks about suicide.
The CDC describes suicide as the result of a combination of factors operating at the individual, relationship, community and societal levels. Risk can be affected by mental health conditions and substance use, but also by social isolation, discrimination, relationship problems, financial difficulties and barriers to healthcare.
That broader context is important because many of the issues young people talk about every day—whether online, in classrooms or among friends—overlap with those sources of stress.
How Climate Change and Uncertainty About the Future Can Affect Youth Mental Health
Climate anxiety is one example.
A major international study published in the Lancet Planetary Health surveyed 10,000 people ages 16 to 25 across 10 countries. Nearly 60 percent said they were “very” or “extremely” worried about climate change, and many reported feelings including sadness, anxiety, anger, powerlessness and guilt.
This does not mean climate change directly causes suicide. But it does show that fears about the future can be a meaningful source of psychological distress for some young people.
Similar themes appear when young people talk about gun violence, war, discrimination, politics or other large-scale problems over which they may feel they have little control.
Financial Stress Can Affect Youth Mental Health, Too
Economic conditions can also affect mental health.
Research has repeatedly found associations between financial hardship and suicide risk. A CDC analysis found lower suicide rates in counties with higher household incomes, greater health insurance coverage and better broadband access. The CDC consequently includes policies that strengthen household financial security and stabilize housing among its recommended suicide-prevention strategies.
A 2020 study published in JAMA Pediatrics similarly found higher suicide rates among children and adolescents living in counties with greater levels of poverty.
For young people, financial pressure may not always mean personally paying rent or worrying about a paycheck. It can mean seeing parents struggle financially, experiencing housing instability, worrying about college costs or entering adulthood believing that economic security will be difficult to achieve.
Again, none of those experiences alone explains suicide, but they help illustrate why prevention cannot be reduced to identifying one telltale behavior.
