Mental health challenges affect millions of Americans across the United States, but significant disparities exist between states in terms of prevalence, access to care, and overall mental well-being. According to multiple reports analyzing data from federal agencies and research organizations, certain states face substantially greater mental health burdens than others. This article examines which states report the highest levels of mental health issues, the factors contributing to these challenges, and what the data reveals about the state of mental health care in America.
State Rankings for Mental Health Challenges
Multiple organizations have conducted comprehensive analyses of mental health across the United States, ranking states based on various indicators of mental well-being and access to care. These rankings consistently identify several states as facing the greatest mental health challenges.
According to Mental Health America's (MHA) "State of Mental Health in America" report using 2022 data, Nevada ranked as having the worst mental health, followed by Arizona and Montana, which tied for the lowest ranking. The report analyzed data from the Substance Abuse and Mental Health Services Administration, the Centers for Disease Control and Prevention, the Department of Health and Human Services, and the Department of Education.
In MHA's 2025 report, Nevada again ranked last, followed by Arizona and Alabama, marking the second consecutive time Nevada and Arizona have ranked at the bottom of the list. This pattern "underscores a high need for strategic investment in mental health in these states," according to MHA.
The Soliant 2025 Best States for Mental Health report identified West Virginia as having the highest number of mentally unhealthy days, ranking it 50th out of 50 states. Louisiana came in second to last at 49th position.
Prevalence of Mental Illness by State
The prevalence of mental illness varies significantly across states, with some states reporting rates substantially higher than the national average. According to available data, the state prevalence of mental illness ranges from 16.19% in New Jersey to 25.03% in Idaho.
Nationally, approximately 23% of U.S. adults experienced mental illness in the past year, equating to nearly 60 million Americans. This figure has remained generally consistent from 2021 to 2024, indicating a persistent mental health crisis in the country.
States with the highest prevalence of mental illness include Idaho (25.03%), followed by other states that were also identified as having among the worst mental health rankings in other reports. This correlation suggests that higher prevalence of mental illness is one factor contributing to the overall poor mental health ratings in certain states.
Contributing Factors to Poor Mental Health
Several factors contribute to the poor mental health outcomes observed in certain states. According to the Soliant report, which analyzed data from the Bureau of Labor Statistics and other sources, these factors include:
- The frequency of "poor mental health days" reported by the population
- Unemployment rate
- Participation in physical activity
- Disconnected youth rate (percentage of teens and young adults aged 16-24 who are neither working nor in school)
- Access to healthy foods
West Virginia, which ranked last in the Soliant report, had the highest average number of mentally unhealthy days reported by residents in the past 30 days, at 6.6 days. The state also has the third-lowest physical activity participation rate (68%) and ties for the second-highest disconnected youth rate in the nation (14%).
Louisiana, which came in second to last, faces similar challenges, though specific statistics were not provided in the source material.
North Dakota, by contrast, ranked as the best state for mental health with 82 points out of 100 possible. The state has the third-lowest unemployment rate in the nation (2.4%), relatively high physical activity participation (78.5%), and low rates of disconnected youth (5%).
Youth Mental Health Challenges
Youth mental health represents a particular concern in several states identified as having the worst mental health outcomes. According to MHA, Nevada had the highest rates of youth depression and youth who didn't receive preventive care in the past year, suggesting a significant lack of services for that group.
Nationally, youth mental health remains in a state of crisis, with approximately 3 million children aged 12 to 17 frequently considering suicide, according to the 2025 MHA report. This statistic highlights the urgent need for improved mental health services and preventive care for young people across the country.
Access to Mental Health Care
Access to mental health care varies significantly from state to state, with needs often going unmet due to a lack of available or affordable services. The MHA report evaluated 17 factors related to access to care, including:
- Adults and youth who experienced mental illness, suicidal thoughts, or substance use disorder in the past year
- Adults and youth who didn't receive necessary treatment, couldn't afford it, or were uninsured
- People with insurance that didn't cover mental or emotional problems
- The availability of mental health providers
States with the worst mental health rankings generally have lower rates of access to care. For example, Nevada's poor rating was partly driven by its high rates of youth who didn't receive preventive care.
In contrast, states with better mental health outcomes have implemented various initiatives to improve access to care. New York, which ranked among the states with the strongest mental health and mental health services, has taken "bold measures to ensure all New Yorkers have access to these critical services," including adding inpatient capacity, expanding outpatient programs, and creating specialized housing. The state has also implemented legislative initiatives to address the harmful impacts of social media and to eliminate the use of smartphones by students in K-12 public schools.
Hawaii, which ranked as the second-highest state for mental health, has "community's collective efforts to expand access to care and support resilience for both adults and youth," according to the State of Hawai'i Department of Health.
Substance Use Disorders
Substance use disorders represent another significant mental health challenge across the United States. According to available data, more than 45 million adults (17.82%) and 2.3 million youth (8.95%) are experiencing a substance use disorder.
While state-specific data on substance use disorders was not provided in the source material, it is reasonable to infer that states with higher rates of mental illness may also face challenges with substance use disorders, given the high comorbidity between these conditions.
Suicidal Ideation
Suicidal ideation represents one of the most concerning aspects of the mental health crisis in the United States. According to available data, nearly 13 million adults (5.04%) reported serious thoughts of suicide. The number of individuals who died by suicide in 2022 was the highest number ever recorded in the U.S., up after slight decreases in 2019 and 2020.
State-specific data on suicidal ideation was not provided in the source material, though Nevada's high rates of youth depression suggest that the state may also face challenges with suicidal thoughts among its population.
State Responses to Mental Health Challenges
In response to these challenges, states with poor mental health rankings have begun implementing various initiatives to improve mental health outcomes. For example, Nevada's health authority has stated that "Addressing the state's mental health crisis remains a top priority for Governor (Joe) Lombardo and policymakers in Nevada."
Similarly, New York has implemented comprehensive mental health reforms, including expanding access to care and addressing youth mental health through legislation targeting social media use and smartphone access in schools.
Conclusion
The data clearly indicates that significant disparities exist in mental health outcomes across the United States, with several states consistently reporting higher rates of mental illness, limited access to care, and greater mental health challenges. Nevada, Arizona, and Alabama rank among the states with the worst mental health outcomes, while states like Massachusetts, Connecticut, and Maine report better mental health outcomes.
These disparities are driven by multiple factors, including unemployment rates, physical activity levels, disconnected youth rates, access to healthy foods, and availability of mental health services. Addressing these challenges will require targeted interventions and increased investment in mental health care in the most affected states.
As Mary Giliberti, interim president and CEO of MHA, noted, "Behind every data point here is a real person who deserves access to timely, quality, affordable mental health care." The persistent mental health crisis in the country underscores the urgent need for comprehensive mental health reform and increased access to care for all Americans.
