Bipolar Disorder: 2025 Statistics
Bipolar disorder impacts tens of millions worldwide—but many face long delays in diagnosis and limited access to care. This guide breaks down who’s affected, the burden of impairment, co-occurring risks, and what’s being done to close treatment gaps and support recovery.

Bipolar disorder is a serious mental health condition characterised by dramatic and often debilitating shifts in mood, energy, and activity levels. It is a chronic illness that can severely impact a person's ability to carry out day-to-day tasks, but it is also a treatable condition.
The headline statistic reveals its profound global impact: bipolar disorder is a leading cause of disability worldwide, affecting an estimated 40 million people. This highlights the urgent need to understand its prevalence, address barriers to care, and improve support for the millions living with the condition and their families.

Overall Prevalence and General Numbers
- Global Prevalence: An estimated 1 in 150 adults worldwide was living with bipolar disorder in 2019.
- U.S. Adult Prevalence: An estimated 4.4% of U.S. adults experience bipolar disorder at some time in their lives. In the past year, 2.8% of adults had the disorder.
- U.S. Adolescent Prevalence: An estimated 2.9% of U.S. adolescents (ages 13-18) have experienced bipolar disorder.
Breakdown by Key Demographics
- By Age (U.S. Adults): The disorder is most prevalent in younger age groups and declines significantly with age:
- Ages 18-29: 4.7%
- Ages 30-44: 3.5%
- Ages 45-59: 2.2%
- Ages 60+: 0.7%
- By Gender: Prevalence is approximately equal between men and women. In the U.S., past-year rates were 2.9% for males and 2.8% for females.
- Age of Onset: The average age of onset is 25 years old, though it can begin as early as childhood.
Co-occurrence and Related Conditions
Co-occurring Conditions: The disorder increases the risk of developing other conditions, particularly anxiety disorders and substance use disorders.
- Physical Health: People with bipolar disorder are more likely to have physical health conditions like cardiovascular or respiratory disease.
- Risk Factors: While genetics play a significant role, adverse life events such as violence or bereavement can trigger or worsen symptoms.
The Most Serious Consequences
- Mortality: On average, people with bipolar disorder die more than 10 years earlier than the general population, often due to associated physical health conditions and increased suicide risk.
- Severe Impairment (U.S. Adults):
- 82.9% of U.S. adults with the disorder experience serious impairment
- Another 17.1% experience moderate impairment that interferes with major life activities.
- Severe Impairment (U.S. Adolescents):
- 2.9% of adolescents had bipolar disorder
- 2.6% had severe impairment.
The Positive Outlook and Solutions
- Effective Interventions: Recovery is possible with proper care, which typically includes a combination of medication (like mood stabilisers) and psychosocial support or therapy.
- The Treatment Gap: Treatment coverage for bipolar disorder is low worldwide, and many individuals are either misdiagnosed or go untreated entirely.
- Barriers to Care: Access is particularly poor in low- and middle-income countries. Widespread stigma can prevent people from seeking help and limit opportunities for education and employment.
Conclusion
The statistics paint a clear picture of bipolar disorder as a prevalent, disabling, and life-threatening condition that disproportionately impacts young people. The data underscores a critical global health challenge: a massive gap between the number of people affected and those who receive care. Closing this gap through increased awareness, reduced stigma, and improved access to treatment is essential to mitigate the disorder's severe consequences and help people manage their condition and lead fulfilling lives.
