Nevada ranks last in the nation for overall mental health, holding the 51st spot (including Washington, D.C.) in Mental Health America’s combined ranking of mental illness prevalence and access to care. The bottom ten states share a pattern: high rates of mental illness paired with limited access to treatment. But the picture is more nuanced than a single ranking suggests, and several states compete for the bottom depending on which measure you look at.
The 10 Lowest-Ranked States
Mental Health America evaluates all 50 states and Washington, D.C. across 17 measures covering both adults and youth. These include rates of depression, substance use, suicidal thoughts, uninsured populations, and access to mental health providers. A ranking of 39 to 51 signals higher prevalence of mental illness and lower access to care. The bottom ten, from bad to worst:
- 42: Oregon
- 43: New Mexico
- 44: Tennessee
- 45: Arkansas
- 46: West Virginia
- 47: Wyoming
- 48: Idaho
- 49: Alabama
- 50: Arizona
- 51: Nevada
What stands out is the geographic spread. These aren’t all in one region. You see Appalachian states like West Virginia and Tennessee alongside Western states like Idaho and Wyoming, plus Southwestern states like Arizona and New Mexico. The common thread isn’t geography. It’s a combination of poverty, rural isolation, and thin healthcare infrastructure.
Youth Mental Health Tells a Different Story
When you isolate youth mental health, some surprising states appear. Nevada again ranks last, with 22.6% of young people experiencing at least one major depressive episode in the past year, roughly 56,000 kids. But Maryland, which ranks well overall, comes in at 50th on this specific measure, with 22.3% of its youth affected. Colorado, another state that performs reasonably well in adult measures, lands at 49th with nearly 22% of its young people reporting a major depressive episode.
Access to basic preventive care for young people is another warning sign. In Nevada, 37.9% of youth had not seen a doctor for a preventive visit in the past year. Idaho was close behind at 37.1%. Texas, which has the largest raw numbers due to its population, saw over 915,000 young people go without a preventive visit. These aren’t just mental health appointments. They’re routine checkups where a provider might catch early signs of depression, anxiety, or substance use before they escalate.
Suicide Rates Point to the Mountain West
Suicide is one of the starkest measures of a state’s mental health crisis, and the pattern here shifts dramatically. The states with the highest age-adjusted suicide rates in 2023, according to the CDC, are concentrated in the Mountain West:
- Alaska: 28.15 per 100,000
- Montana: 26.65 per 100,000
- Wyoming: 26.31 per 100,000
- Idaho: 23.28 per 100,000
- New Mexico: 22.76 per 100,000
Alaska’s rate is more than double the national average. Montana and Wyoming are close behind. All five of these states are characterized by vast distances between communities, harsh winters, high rates of gun ownership, and limited access to crisis services. Research consistently shows that suicide risk is elevated in disadvantaged, socially fragmented rural communities rather than urban ones. A person in crisis in rural Wyoming may be hours from the nearest emergency psychiatric provider.
Why These States Rank So Poorly
The factors driving poor mental health outcomes at the state level are well documented. Poverty is the most consistent predictor. Children growing up in socioeconomic disadvantage are two to three times more likely to experience mental health problems than their peers, and the risk increases with both the duration and severity of poverty. Kids in poverty are also more likely to be exposed to violence at home or in their neighborhoods, compounding the psychological toll. These effects stretch across a lifetime.
Income inequality matters at the population level too. Countries and regions with wider gaps between rich and poor tend to have worse overall mental health. Employment instability, food insecurity, lack of affordable housing, and limited education all feed into the cycle. Many of the bottom-ranked states have above-average poverty rates combined with below-average spending on social services.
Then there’s the provider shortage. Federal data tracking mental health professional shortage areas shows that Alabama meets only 28.4% of its population’s mental health care needs through its current provider workforce. Mississippi meets just 20.6%. Texas covers 24.9%. These numbers mean that for every mental health professional available, there are three to five times more people who need care than that provider can serve. In practical terms, this translates to months-long waitlists, drives of 60 miles or more to see a therapist, or simply going without treatment entirely.
What Separates the Best States From the Worst
States that rank in the top 13, places like Massachusetts, Connecticut, and Vermont, share a few characteristics. They tend to have higher per-capita income, more robust Medicaid programs, greater density of mental health providers, and stronger integration of behavioral health into primary care. Many expanded Medicaid under the Affordable Care Act early and invested in community mental health centers.
The bottom-ranked states often lack these structural advantages. Several were late to expand Medicaid or haven’t expanded it at all. Their rural populations face both the social isolation that increases mental health risk and the provider deserts that make treatment inaccessible. When people can’t access care, conditions worsen, crises escalate, and the state’s overall outcomes drop further.
Nevada’s last-place ranking reflects this combination acutely. It has high rates of mental illness across age groups, one of the lowest rates of youth preventive care in the country, and a behavioral health workforce that can’t keep pace with a rapidly growing population. The state’s heavy reliance on tourism and service-industry employment also means a large share of workers face irregular schedules, limited benefits, and the kind of economic instability closely linked to poor mental health.
No Single “Worst” State
The answer to which state has the worst mental health depends on the measure. Nevada ranks last overall. Alaska has the highest suicide rate. Mississippi has the largest gap between mental health needs and available providers. Oregon and Colorado have some of the highest youth depression rates in the country despite ranking better on other measures. Each of these states struggles with a different piece of the mental health puzzle, and none of them is getting the full picture right.
