    Suicide prevention explained: what works and where to get help

    Suicide is preventable: WHO says timely, evidence-based and often low-cost interventions can prevent it.[1] Proven approaches include crisis lines such as 988, safety planning with follow-up after an emergency visit, limiting access to means at the population level, responsible media reporting and better identification and follow-up in health care.[2][3][4]

    If you are thinking about suicide, or worried about someone, help is available now. In the US, call or text 988 or chat at 988lifeline.org; it is free, confidential and open 24 hours a day.[2] Veterans can press 1 after dialling 988.[5] In the UK and Ireland, call Samaritans free on 116 123, day or night.[6] Elsewhere, find a local helpline at findahelpline.com.[7] In an emergency, call your local emergency number.

    Suicide is a public health problem that can be prevented.[1] Most people who survive a suicide attempt go on to live out their lives, and support at the right moment matters.[8] This explainer covers what the evidence says works, the latest data, and how prevention is organised. It follows international safe-messaging guidance and is not medical advice: anyone struggling should talk to a clinician or contact a crisis line.

    Why prevention is possible

    Suicide has many causes, and it is not inevitable. WHO links it to mental health conditions such as depression and alcohol use disorders and to a previous attempt, but says many suicidal crises happen in moments of acute stress, such as money problems, relationship breakdown or chronic pain.[9] Crises can pass. Getting someone through that moment, and connecting them to ongoing care, saves lives.[1][8] Stigma is a major barrier, because it stops people from asking for help.[10]

    WHO frames suicide as requiring a multisectoral public health response across health, education, labour, agriculture, justice and the media.[11][1] Risk is elevated among people with depression and alcohol use disorders, after a previous attempt, and among groups facing discrimination, including refugees and migrants, Indigenous peoples, LGBTI people and prisoners.[9][12] Yet only 38 countries report having a national suicide prevention strategy.[10] Data quality is a constraint too: only about 80 WHO member states have good-quality vital registration for suicide.[13]

    What works

    WHO’s LIVE LIFE initiative recommends four core interventions: limiting access to the means of suicide, working with the media on responsible reporting, building socio-emotional life skills in adolescents, and early identification, assessment, management and follow-up of anyone affected by suicidal behaviour.[4]

    • Crisis lines. The 988 Suicide & Crisis Lifeline connects callers, texters and chatters to a network of over 200 local crisis centers.[2] The Lifeline says evaluations by a Columbia University team show callers feel less suicidal and more hopeful after contact.[14] An observational JAMA study estimated that suicides among 15- to 34-year-olds were 11% lower than expected in the first two and a half years after 988 launched, though it could not prove cause and effect.[15][16]
    • Safety planning and follow-up. A safety plan is a short, personalised list, written with a clinician, of warning signs, coping strategies, people to contact and professional services for a crisis.[17] In a 2018 study in US emergency departments, a brief Safety Planning Intervention plus structured follow-up phone calls was associated with 45% fewer suicidal behaviours over six months and patients were more than twice as likely to attend mental health treatment.[3] The study was a cohort comparison rather than a randomised trial.[18]
    • Safer health systems. The Zero Suicide framework asks health systems to commit to safer suicide care across screening, treatment and follow-up, on the premise that deaths among people in care are preventable.[19] Its backers note that most people who die by suicide saw a health care provider in the prior year.[20]
    • Population means safety. WHO counts limiting access to the means of suicide among its most effective population-level measures.[4] WHO treats this as a population-level policy measure; in line with safe-messaging guidance, we do not discuss specific means.
    • Treating depression. Depression is a major risk factor, and effective treatment for it exists.[21] See Depression explained.

    The numbers, in context

    WHO estimates that 727,000 people died by suicide worldwide in 2021, and that it was the third leading cause of death among 15- to 29-year-olds.[22] In the US, CDC counted 48,824 suicide deaths in 2024, slightly fewer than in 2023.[23] Behind every number is a person, and each death deeply affects families and communities.[24]

    CDC’s NCHS reported an age-adjusted rate of 13.7 per 100,000 in 2024, down from 14.1 in 2023; the rate rose between 2014 and 2017 and has shown no significant change since.[23][25] Rates fell between 2023 and 2024 for women aged 25 and older and for males aged 15–24 and 25–44.[26] In 2023 suicide was the second leading cause of death for people aged 10 to 34.[27] Survey data show 5.5% of US adults had serious thoughts of suicide in 2024, highest among those aged 18–25.[28] Globally, 73% of suicides occur in low- and middle-income countries, where registration data are weakest.[22][13]

    World Suicide Prevention Day

    World Suicide Prevention Day falls on 10 September each year. It is organised by the International Association for Suicide Prevention (IASP) and co-sponsored by WHO to raise awareness that suicide can be prevented.[29] The 2026 day marked the third and final year of IASP’s theme, “Changing the Narrative on Suicide”, which encourages open, honest conversations.[30]

    How to help someone

    If you are worried about someone, the 988 Lifeline says you can call, text or chat with a counselor to get help for a friend or loved one, not only for yourself.[31] Conversations are confidential.[32] For more on the national line, see the 988 Lifeline page, the 988 and crisis-care tracker and the crisis-line funding debate.

    Questions readers ask

    Where can I get help right now if I am thinking about suicide?

    In the US, call or text 988 or chat at 988lifeline.org; it is free, confidential and available 24 hours a day. In the UK and Ireland, call Samaritans free on 116 123, day or night. In other countries, Find A Helpline lists verified services in more than 175 countries.[2][6][7]

    Can suicide be prevented?

    Yes. WHO says suicides can be prevented with timely, evidence-based and often low-cost interventions, and the 988 Lifeline notes that over 90% of people who attempt suicide go on to live out their lives.[1][8]

    What is a safety plan?

    A safety plan is a brief clinical intervention in which a person and a clinician write a prioritised list of coping strategies, people who can help and professional contacts for a crisis. In a 2018 US emergency department study, safety planning plus follow-up calls was associated with 45% fewer suicidal behaviours over six months than usual care.[17][3][18]

    How many people die by suicide in the US?

    CDC reported 48,824 suicide deaths in 2024, a rate of 13.7 per 100,000, slightly down from 2023. The rate has not changed significantly since 2017.[23][25]

    When is World Suicide Prevention Day?

    Every year on 10 September. It is organised by the International Association for Suicide Prevention and co-sponsored by WHO. 2026 was the final year of the theme "Changing the Narrative on Suicide".[29][30]
