Youth Mental Health: 2025 Statistics

Back to Top

Adolescence is a critical and formative period for mental, social, and emotional development. However, mental health conditions are a major cause of illness and disability among young people, significantly impacting their education, relationships, and long-term well-being.

Globally, an estimated 1 in 7 (14%) of all 10 to 19-year-olds experiences a mental health condition. This means millions of young people are navigating a crucial stage of life while also struggling with disorders that are often unrecognised and untreated, leading to profound and lasting consequences.

Overall Prevalence and General Numbers

• Global Burden: Mental health conditions account for 15% of the total burden of disease and injury in people aged 10 to 19.
• Leading Disorders: Depression, anxiety, and behavioural disorders are among the leading causes of illness and disability for this age group.
• Prevalence of Common Disorders (Global, ages 10-19):
  • Anxiety Disorders: Affects 4.4% of 10-14 year-olds and 5.5% of 15-19 year-olds.
  • Depression: Affects 1.4% of 10-14 year-olds and 3.5% of 15-19 year-olds.
  • ADHD: Affects 2.9% of 10-14 year-olds and 2.2% of 15-19 year-olds.

Breakdown by Key Demographics

• By Age Group (US Data):
  • In 2021, 20.1% of US adolescents (ages 12-17) experienced a major depressive episode (MDE).
  • Of those with MDE, 75.5% experienced severe impairment in their daily functioning.
• By Gender (US Data):
  • There is a significant gender disparity in depression. The prevalence of MDE among adolescent females was 29.2%, nearly three times higher than for males at 11.5%.
• By Race/Ethnicity (US Data):
  • The prevalence of MDE was highest among adolescents reporting Two or More Races, at 27.2%.

Co-occurrence and Related Conditions

• Exposure to Adversity: Experiencing poverty, abuse, neglect, or violence is a major risk factor.
• Social and Media Pressures: Bullying, peer pressure, and media influence that exacerbates disparities between an adolescent's lived reality and their aspirations are key contributors.
• Family Environment: A poor quality of home life, harsh parenting, and family conflict can increase risk.
• Identity Exploration: Adolescents from minority groups, including those exploring their sexual orientation and gender identity, can face unique challenges that impact mental health.
• Substance Use: Early use of alcohol, tobacco, or cannabis is often linked to underlying emotional difficulties.

The Most Serious Consequences

• Suicide and Self-Harm:
  • Suicide is the third leading cause of death among 15 to 29-year-olds globally.
  • In the US, 20% of adolescents had serious thoughts of suicide, and 9% made a suicide attempt.
• Academic Impact:
  • Mental health disorders are a significant cause of school dropout and lower educational attainment.
  • In the US, students with depression are twice as likely to drop out of school compared to their peers.
• Long-Term Implications:
  • Many adult mental health disorders begin in adolescence. Failure to treat them early can lead to chronic conditions and limited opportunities in adulthood.

The Positive Outlook and Solutions

While the challenges are significant, effective evidence-based strategies for prevention and treatment exist, though access remains a critical issue.

• Effective Interventions: Psychosocial interventions like Cognitive Behavioural Therapy (CBT) and school-based programmes that promote socio-emotional learning are proven to be effective.
• The Global Treatment Gap: The majority of young people with mental health conditions receive no care. In low- and middle-income countries, this gap can exceed 75%.
• US Treatment Gap: Even in the US, access is a major problem. Only 40.6% of adolescents with a major depressive episode received any treatment.
• A Call for Action: Global organisations like the WHO and UNICEF, along with national bodies like the U.S. Surgeon General, are calling for a "whole-of-society" effort to improve prevention, early identification, and equitable access to care.

Conclusion

Youth mental health is a global crisis defined by high prevalence and a profound, persistent gap in care. One in seven adolescents worldwide is affected, yet the majority do not receive the support they need. The consequences—including academic failure, substance use, and suicide—are severe. Addressing this crisis requires a unified effort from families, schools, communities, and governments to implement proven prevention strategies and ensure every young person has access to timely, effective care.
