WHO estimates that about 727,000 people died by suicide in 2021, and many more made suicide attempts. Each death deeply affects families, friends and communities. Suicide was the third leading cause of death among people aged 15 to 29, and close to three quarters of suicides occurred in low- and middle-income countries. Suicide is linked to mental disorders, particularly depression and alcohol use disorders, but many suicides happen in moments of acute crisis, when a person's ability to cope with stress such as financial problems, relationship disputes, chronic pain or illness breaks down. A previous suicide attempt is one of the most important risk factors.
Men die by suicide at about twice the rate of women. Groups that face discrimination, including refugees and migrants, indigenous peoples, LGBTI people and people in prison, have higher rates, as do people who have experienced conflict, disaster, violence, abuse, loss or isolation. With timely, evidence-based and often low-cost interventions, suicides can be prevented. WHO recommends four interventions with good evidence: limiting access to common means, responsible media reporting, building young people's social and emotional skills, and early identification and follow-up of people at risk. Yet WHO reports that only 38 countries have a national suicide prevention strategy, stigma still keeps many people from seeking help, and in at least 23 countries suicide attempts remain a criminal offence.
