Mental Health Statistics

Mental health conditions affect millions of people across the United States each year. In 2024, over 1 in 5 U.S. adults experienced mental illness, totaling roughly 61.5 million people. 

Mental health statistics help show how common these conditions are, who faces the highest risks, and where gaps in treatment and support still exist.

How Many People in the U.S. Face Mental Health Issues in 2026?

Mental health conditions remain one of the most widespread health concerns in the United States. 

Millions of adults and adolescents experience conditions that affect their mood, relationships, work, education, and overall quality of life.

Core 2026 mental health statistics show:

• More than 23% of U.S. adults experienced a mental illness within the past year, totaling over 60 million people.
• Roughly 19.1% of adults reported having depression or receiving treatment for depression in early 2026.
• About 14.6 million adults in the U.S. live with a serious mental illness that substantially interferes with daily functioning.
• Nearly 30% of adolescents ages 12 to 17 are expected to experience anxiety or depression.
• More than 15% of high school students may experience suicidal thoughts or ideation.
• Mental health awareness continues to grow. About 38% of Americans planned to make a mental health-related New Year’s resolution for 2026, marking a 5% increase from the previous year.

These statistics show that mental health issues affect people across every age group, background, and community. They also highlight the growing demand for accessible mental health treatment and long-term support.

Mental Health Statistics Worldwide

Mental health disorders affect people in every country, culture, and age group. 

As of 2026, an estimated 970 million to more than 1 billion people worldwide are living with a mental health condition, making mental illness one of the leading causes of disability globally.

Some of the most significant global mental health statistics include:

• Roughly 1 in 8 people worldwide live with a mental health disorder.
• About 1 in 4 people are expected to experience a mental health condition at some point in their lives.
• Anxiety disorders affect approximately 301 million people globally, making them the most common mental health condition worldwide.
• Depression affects roughly 280 million people worldwide and remains a leading contributor to disability and reduced quality of life.

The COVID-19 pandemic also increased mental health concerns across many countries. Despite growing awareness, more than 75% of people in low- and middle-income countries still do not receive mental health treatment.

Statistics on Mental Health Issues vs. Mental Health Disorders

Mental health issues and mental health disorders are not always the same thing. Many people experience temporary stress, grief, burnout, or emotional distress without meeting the criteria for a diagnosable mental health condition.

Mental health disorders are clinically recognized conditions that significantly affect a person’s thoughts, emotions, behaviors, or daily functioning.

Recent statistics show:

• Roughly 23% to 26% of U.S. adults experience a diagnosable mental health disorder each year.
• About 5.6% of adults live with a serious mental illness that substantially interferes with work, relationships, or everyday life.
• An estimated 16.5% to 20% of young people experience a diagnosable mental health disorder.

At the same time, many more people experience temporary mental health struggles linked to stress, trauma, financial pressure, relationships, or major life changes. 

While these challenges may not always develop into long-term disorders, they can still significantly affect overall wellbeing and quality of life.

Mental Health by State: Access to Care and Prevalence Rates

Mental health rates and access to treatment vary significantly by state. Factors like insurance coverage, provider shortages, rural populations, and public mental health funding can all affect how easily people receive care.

According to 2025 rankings, states with lower mental illness rates and stronger access to care ranked highest overall, while many Southern and rural states faced greater barriers to treatment.

Top-ranking states for mental health access and lower prevalence rates include:

• New York
• Hawaii
• New Jersey
• Vermont
• Iowa

States facing some of the highest mental health burdens and lowest access to care include:

• Nevada
• Arizona
• Alabama
• Idaho
• Wyoming

Additional state-level mental health statistics show:

• Nearly 20% of adults with mental illness in Tennessee, Mississippi, and Texas were uninsured.
• Almost 40% of adults with mental illness in Wisconsin, Utah, and Wyoming reported unmet mental health treatment needs.
• Maine and Arkansas reported some of the lowest unmet mental health care rates nationwide.
• Vermont, Maryland, and Rhode Island ranked among the best states for mental health insurance coverage.

These differences highlight how geography, healthcare infrastructure, and state policy can directly affect mental health outcomes and access to treatment across the United States.

Statistics on Mental Health Conditions by Type

Mental health disorders include a wide range of conditions that affect mood, thinking, behavior, emotional regulation, and daily functioning. 

Some disorders are relatively common and mild, while others can severely disrupt a person’s relationships, education, employment, or ability to live independently.

The following mental health statistics show how different conditions affect people across the United States and worldwide.

Anxiety Disorders

Anxiety disorders are the most common mental health conditions worldwide and among the most common in the United States. These disorders include generalized anxiety disorder (GAD), panic disorder, social anxiety disorder, and specific phobias.

Anxiety disorder statistics include:

• Approximately 301 million people worldwide live with an anxiety disorder.
• Nearly 19% of U.S. adults experience an anxiety disorder each year.
• Anxiety disorders are more common among women and adolescents than men.

Despite how common anxiety disorders are, many people never receive treatment or professional support.

Depression

Depression is one of the leading causes of disability worldwide. Major depressive disorder can affect a person’s mood, sleep, energy levels, concentration, and ability to function day-to-day.

Recent depression statistics show:

• Roughly 280 million people globally live with depression.
• About 21 million U.S. adults experience at least one major depressive episode annually.
• Depression rates among adolescents and young adults have increased significantly in recent years.

Depression can range from mild to severe and is strongly linked to increased suicide risk when left untreated.

Bipolar Disorders

Bipolar disorder causes significant shifts in mood, energy, and activity levels. People with bipolar disorder may experience periods of depression alongside episodes of mania or hypomania.

Important bipolar disorder statistics include:

• Around 40 million people worldwide live with bipolar disorder.
• Approximately 2.8% of U.S. adults experience bipolar disorder each year.
• Symptoms often begin during late adolescence or early adulthood.

Bipolar disorder can interfere with relationships, employment, and daily stability, particularly without ongoing treatment.

PTSD

Post-traumatic stress disorder (PTSD) can develop after experiencing or witnessing traumatic events such as violence, abuse, military combat, accidents, or natural disasters.

PTSD statistics show:

• Roughly 3.9% of people worldwide experience PTSD at some point in their lives.
• About 6% of U.S. adults will experience PTSD during their lifetime.
• Women are more likely than men to develop PTSD.

PTSD is especially common among veterans, abuse survivors, and people exposed to repeated trauma.

Schizophrenia

Schizophrenia is a serious mental health disorder that affects perception, thinking, emotions, and behavior. Symptoms may include hallucinations, delusions, disorganized thinking, and social withdrawal.

Core schizophrenia statistics include:

• Approximately 24 million people worldwide live with schizophrenia.
• Schizophrenia affects about 1 in 300 people globally.
• Symptoms most commonly appear in late adolescence or early adulthood.

Although schizophrenia is less common than anxiety or depression, it is among the most severe and disabling mental health conditions.

Eating Disorders

Eating disorders involve unhealthy relationships with food, body image, and eating behaviors. Common disorders include anorexia nervosa, bulimia nervosa, and binge eating disorder.

Recent eating disorder statistics show:

• More than 28 million Americans are expected to experience an eating disorder during their lifetime.
• Eating disorders have one of the highest mortality rates among mental health conditions.
• Adolescents and young adults face especially high risks.

Eating disorders can lead to severe physical health complications alongside emotional and psychological distress.

Behavior Disorders

Behavior disorders often begin during childhood and involve persistent patterns of disruptive, impulsive, or aggressive behavior. Common examples include oppositional defiant disorder (ODD) and conduct disorder.

Behavior disorder statistics include:

• Behavioral disorders affect millions of children and adolescents worldwide.
• Boys are diagnosed with behavior disorders more frequently than girls.
• Many people with untreated behavior disorders also experience anxiety, depression, or substance use disorders later in life.

Early intervention and family support can significantly improve long-term outcomes.

Developmental  Disorders

Developmental disorders affect cognitive, emotional, social, or behavioral development. These conditions often begin during childhood and may continue into adulthood.

Examples include autism spectrum disorder (ASD), intellectual disabilities, and communication disorders.

Developmental disorder statistics show:

• About 1 in 36 U.S. children has been identified with autism spectrum disorder.
• Developmental disorders are often diagnosed during early childhood.
• Many individuals with developmental disorders also experience co-occurring mental health conditions.

Access to early diagnosis and specialized support services can improve quality of life and long-term functioning.

Other Mental Health Disorders

Other mental health disorders affect millions of people across the United States and worldwide. These conditions vary widely in symptoms, severity, and treatment needs.

Additional mental health statistics by type of condition include:

• Obsessive-compulsive disorder (OCD) affects roughly 1% to 2% of people worldwide.
• Attention-deficit/hyperactivity disorder (ADHD) affects millions of children and adults globally.
• Personality disorders affect an estimated 9% of U.S. adults.
• Substance use disorders frequently co-occur with mental illness, particularly anxiety, depression, and PTSD.

Together, these statistics highlight the broad scope of mental health conditions and the importance of accessible treatment, early intervention, and long-term support.

Mental Health Rates by Demographic

Mental health conditions affect people of every age, gender, race, and background. However, some groups face higher rates of certain disorders, greater barriers to treatment, or increased risks tied to social, economic, or biological factors.

The following mental health statistics break down how mental health conditions affect different demographic groups across the United States.

Mental Health Issues in Men vs. Women

Mental health rates and symptoms often differ between men and women. Women are more likely to be diagnosed with mood and anxiety disorders, while men face higher rates of substance use disorders and suicide deaths.

Mental health statistics by sex include:

• Women are nearly twice as likely as men to experience anxiety disorders.
• Major depression affects women more frequently than men, particularly during adolescence and early adulthood.
• Men have lower reported rates of anxiety and depression, but are less likely to seek mental health treatment.
• Men die by suicide at significantly higher rates than women in the United States.
• Women are more likely to experience PTSD, partly due to higher rates of sexual violence and interpersonal trauma.
• Substance use disorders are more common among males, especially involving alcohol and illicit drugs.
• Eating disorders are diagnosed more frequently in females, although rates among males are believed to be underreported.
• Boys are more commonly diagnosed with behavioral and developmental disorders, including ADHD and conduct disorders.

These differences show how mental health conditions can affect males and females in different ways, both biologically and socially. Treatment needs, symptoms, and barriers to care may also vary significantly between groups.

Mental Health Issues by Age

Mental health conditions can affect people at any stage of life, but prevalence rates often vary by age group. 

Younger adults and adolescents consistently report some of the highest rates of mental illness, anxiety, and depression in the United States.

Key mental health statistics by age include:

• Young adults ages 18 to 25 have the highest rates of mental illness among all adult age groups in the U.S.
• More than 1 in 3 young adults reported experiencing a mental illness within the past year.
• Nearly 30% of adolescents ages 12 to 17 are expected to experience anxiety or depression.
• About 20% of youth ages 13 to 18 live with a mental health condition.
• More than 15% of high school students report serious thoughts of suicide.
• Mental health disorders often begin early in life, with around half of all mental health conditions starting by age 14.
• Older adults experience mental health challenges as well, particularly depression, anxiety, grief-related disorders, and cognitive conditions linked to aging.

Social isolation, chronic illness, financial stress, and loss of independence can all increase mental health risks among older adults.

As shown by these statistics, mental health needs can change throughout life. Early intervention, age-appropriate support, and accessible treatment remain important across every age group.

Mental Health Issues by Sexual Orientation

LGBTQ+ individuals experience significantly higher rates of mental health issues compared to heterosexual and cisgender populations. 

Discrimination, stigma, bullying, family rejection, and social isolation can all contribute to increased mental health risks.

Recent statistics on mental health and sexual orientation show:

• More than 39% of LGBTQ+ young people seriously considered suicide in the past year.
• LGBTQ+ youth who experienced discrimination reported substantially higher rates of anxiety, depression, and self-harm.
• Nearly half of LGBTQ+ youth reported symptoms of anxiety.
• Lesbian, gay, and bisexual adults are more likely to experience mental illness and substance use disorders than heterosexual adults.

Mental health statistics by orientation also show differences between groups:

• Bisexual youth and adults consistently report some of the highest rates of anxiety, depression, and suicidal thoughts.
• Transgender and nonbinary youth face especially high mental health risks, including elevated rates of depression, self-harm, and suicide attempts.
• Gay and lesbian individuals report higher rates of mood disorders and discrimination-related stress compared to heterosexual populations.
• LGBTQ+ youth with supportive families and communities report significantly lower suicide attempt rates and better mental health outcomes.

These statistics highlight the strong connection between social support, acceptance, and mental wellbeing among LGBTQ+ individuals.

Mental Health Issues in Different Racial Groups

Every race and ethnicity is affected by mental health conditions, but diagnosis rates, access to treatment, cultural stigma, and barriers to care can vary widely between groups. 

Historical trauma, discrimination, poverty, and limited access to culturally competent healthcare may also increase mental health risks in some communities.

Mental health statistics by racial and ethnic group include:

• Multiracial adults report the highest rates of mental illness among racial groups in the United States.
• American Indian and Alaska Native adults experience disproportionately high rates of PTSD, substance use disorders, and serious psychological distress.
• Black adults are more likely to experience persistent symptoms of emotional distress, yet are less likely to receive mental health treatment than white adults.
• Asian American adults report lower diagnosed mental illness rates overall, though experts believe mental health conditions may be underreported due to stigma and reduced treatment-seeking.
• Hispanic and Latino populations face growing rates of anxiety and depression, particularly among adolescents and young adults.
• White adults are more likely to access mental health treatment services compared to many minority populations.
• People from minority racial groups are more likely to experience barriers to care. This includes lack of insurance coverage, provider shortages, language barriers, and cultural stigma surrounding mental health treatment.
• Black and Hispanic adults are less likely to receive adequate mental health care, even when symptoms are similar to those reported by white adults.

As shown by these rates, mental health outcomes are influenced not only by individual conditions, but also by healthcare access, economic inequality, cultural attitudes, and systemic disparities in treatment and diagnosis.

Statistics on Risk Factors for Mental Health Disorders

Mental health disorders develop from a combination of biological, psychological, environmental, and social factors. 

While no single cause explains every condition, research shows that certain experiences and circumstances can significantly increase mental health risks.

Statistics on mental health risk factors include:

• Age: Young adults ages 18 to 25 reported the highest mental illness rates at 36.2%, making age one of the strongest mental health risk factors.
• Sex: Females reported higher overall mental illness rates (26.4%) than males, particularly for anxiety and depressive disorders.
• Traumatic experiences are among the most significant risk factors for mental illness. Studies show strong links between trauma exposure, PTSD, anxiety, depression, and substance use disorders.
• Family history and genetic predisposition play a major role in mental health risk, particularly for conditions like bipolar disorder, schizophrenia, anxiety, and depression.
• Chronic stress related to finances, work, caregiving, or relationships is strongly associated with increased anxiety and depressive symptoms.
• Children exposed to family dysfunction, abuse, neglect, or domestic violence face significantly higher risks of developing mental health disorders later in life.
• Social isolation and loneliness are also linked to increased rates of depression, anxiety, and suicidal thoughts across multiple age groups.

As the numbers highlight, mental health disorders are often influenced by multiple overlapping risk factors rather than a single cause alone.

Statistics on Mental Health Treatment in the U.S.

Mental health treatment has become increasingly common in the United States as awareness, screening, and access to behavioral healthcare continue to grow. Treatment may include therapy, counseling, prescription medication, inpatient care, outpatient programs, or a combination of approaches depending on a person’s needs.

Recent mental health treatment statistics for the United States show:

• About 30 million U.S. adults with mental illness received mental health treatment within the past year.
• Roughly 50.6% of adults with any mental illness received some form of treatment or counseling.
• Around 62% of adults with serious mental illness received mental health treatment.
• Approximately 23.9% of U.S. adults received mental health treatment in a recent year, up from 19.2% in 2019.
• About 16.5% of adults reported taking prescription medication for mental health conditions.
• Roughly 10% to 14% of adults received counseling or therapy from a mental health professional.
• Women are more likely than men to receive mental health treatment, including both therapy and prescription medication.
• Young adults ages 18 to 44 showed some of the largest increases in treatment rates in recent years.

The numbers reflect the growing role mental health treatment plays in healthcare across the United States. 

In recent years, more people are seeking support for anxiety, depression, trauma-related disorders, and other mental health conditions.

Statistics on Effects of Mental Health

Having a mental health issue can impact nearly every area of a person’s life, including physical health, relationships, education, employment, and financial stability. 

The effects often extend beyond individuals, impacting families, workplaces, healthcare systems, and the broader economy.

The following statistics show how mental health disorders affect individuals, families, and communities across the United States.

Statistics on Effects of Mental Health on Individuals

Effects of mental illness on a person include effects to physical health, education, employment, and long-term wellbeing. 

Many people living with mental illness also face increased risks of chronic disease, substance use, and financial instability.

Statistics on the effects of mental health conditions on individuals include:

• People with mental illness face up to twice the risk of cardiometabolic disease compared to those without mental illness.
• Individuals with depression have a 40% higher risk of developing conditions like heart disease, hypertension, stroke, diabetes, metabolic syndrome, or obesity.
• Roughly 34.5% of U.S. adults with mental illness also have a substance use disorder, showing a strong connection between mental health and addiction.
• About 6.9% of adults with mental illness are unemployed, compared to 4.3% of adults without mental illness.
• High school students with recent depression symptoms are more than twice as likely to drop out of school compared to their peers.
• Children ages 6 to 17 with mental, emotional, or behavioral disorders are more than twice as likely to repeat a grade in school.

Statistics on Effects of Mental Health on Families

Entire families face the effects of mental health issues, not just the individual experiencing symptoms. Family members may take on caregiving responsibilities, provide financial support, or experience emotional stress related to a loved one’s mental health condition.

Core statistics on the effects of mental health on families include:

• At least 8.4 million people in the United States provide care to an adult with a mental or emotional health issue.
• Caregivers spend an average of 32 hours per week providing unpaid support and care for adults with mental health conditions.
• Family caregivers commonly report increased stress, burnout, anxiety, sleep problems, and financial strain related to caregiving responsibilities.
• When local treatment options are unavailable, families may be forced to send loved ones far from home for care, which can increase emotional distress, separation trauma, and disruptions to family support systems.

Statistics on Effects of Mental Health on the Economy

Healthcare systems, workplaces, housing systems, and the broader U.S. economy also feel the strain of the weight of mental health issues.

Serious mental illness is associated with increased healthcare costs, reduced workforce participation, and higher rates of hospitalization and homelessness.

Statistics on the economic effects of mental health include:

• Serious mental illness contributes to roughly $193.2 billion in lost earnings each year across the U.S. economy.
• Schizophrenia alone created an estimated economic burden of $343.2 billion in the United States in 2019.
• About 12.3% of emergency department visits by U.S. adults are related to mental health concerns.
• Mental health and substance use disorders led to more than 1.65 million inpatient hospitalizations in the United States during 2022.
• Depressive disorders are the second-leading cause of inpatient hospitalization among people under 18, excluding pregnancy- and birth-related admissions.
• In 2024, approximately 18.1% of people experiencing homelessness in the United States had a serious mental illness.
• Roughly 17.6% of U.S. veterans experienced a mental illness in 2023, totaling about 3.5 million people.
• About 9.6% of active-duty U.S. military service members experienced a mental health or substance use condition in 2021.

Statistics on Mental Health Prevention

Mental health prevention efforts focus on reducing risk factors and identifying mental health concerns before symptoms become severe. 

Research shows that early intervention, especially during childhood and adolescence, can significantly improve long-term mental health outcomes.

An estimated 25% to 50% of adult mental health disorders may be preventable through early intervention during childhood and adolescence.

Early mental health support for children and teens can reduce the long-term risk of anxiety, depression, substance use disorders, and suicidal behaviors.

The economic benefits of early childhood mental health interventions exceed costs by an average ratio of 1 to 6, showing substantial long-term financial and public health benefits.

Prevention strategies that include family support, school-based mental health programs, and early screening have been linked to improved emotional wellbeing and reduced mental health crises later in life.

Statistics on Untreated Mental Health Issues in the U.S.

Although mental health treatment rates have increased in recent years, millions of Americans still do not receive the care they need. 

Cost, provider shortages, lack of insurance coverage, stigma, and limited access to local services all remain major barriers to treatment.

Statistics on untreated mental health issues in the United States include:

• More than 61 million U.S. adults experienced mental illness in 2024, representing roughly 23.4% of the adult population.
• Approximately 57% of adults with mental illness received no treatment or medication for their condition.
• Nearly 40% of young people with depression did not receive mental health treatment or support services.
• Roughly 5 million adults with mental illness remain uninsured, creating significant barriers to accessing therapy, medication, and psychiatric care.
• Untreated mental health conditions cost the United States more than $282 billion annually through lost productivity, healthcare expenses, disability, and related social costs.
• People with untreated mental illness face higher risks of unemployment, homelessness, substance use disorders, hospitalization, and suicide.

The Growing Need for Accessible, Individualized Mental Health Treatment

Mental health conditions affect millions of people across the United States, yet many individuals still struggle to access timely, effective care.
