Mental Health By The Numbers
Millions of Americans are affected by mental health conditions every year. Here are some facts about the prevalence and impact of mental illness.
Prevalence of Mental Illness
- Approximately 1 in 5 adults in the U.S.—43.8 million, or 18.5%—experiences mental illness in a given year.1
- Approximately 1 in 25 adults in the U.S.—10 million, or 4.2%—experiences a serious mental illness in a given year that substantially interferes with or limits one or more major life activities.
- Approximately 1 in 5 youth aged 13–18 (21.4%) experiences a severe mental disorder at some point during their life. For children aged 8–15, the estimate is 13%.3
- 1.1% of adults in the U.S. live with schizophrenia.
- 2.6% of adults in the U.S. live with bipolar disorder.
- 6.9% of adults in the U.S.—16 million—had at least one major depressive episode in the past year.
- 18.1% of adults in the U.S. experienced an anxiety disorder such as posttraumatic stress disorder, obsessive-compulsive disorder and specific phobias.
- Among the 20.2 million adults in the U.S. who experienced a substance use disorder, 50.5%—10.2 million adults—had a co-occurring mental illness.
- An estimated 26% of homeless adults staying in shelters live with serious mental illness and an estimated 46% live with severe mental illness and/or substance use disorders.9
- Approximately 20% of state prisoners and 21% of local jail prisoners have “a recent history” of a mental health condition.10
- 70% of youth in juvenile justice systems have at least one mental health condition and at least 20% live with a serious mental illness.11
- Only 41% of adults in the U.S. with a mental health condition received mental health services in the past year. Among adults with a serious mental illness, 62.9% received mental health services in the past year.8

- African Americans and Hispanic Americans used mental health services at about one-half the rate of Caucasian Americans in the past year and Asian Americans at about one-third the rate.13
- Half of all chronic mental illness begins by age 14; three-quarters by age 24. Despite effective treatment, there are long delays—sometimes decades—between the first appearance of symptoms and when people get help.14
Consequences of Lack of Treatment
- Serious mental illness costs America $193.2 billion in lost earnings per year.15
- Mood disorders, including major depression, dysthymic disorder and bipolar disorder, are the third most common cause of hospitalization in the U.S. for both youth and adults aged 18–44.16
