The answer: Wyoming (with Montana and Alaska close behind)

Wyoming has topped or near-topped CDC rankings for years, with an age-adjusted suicide rate around 30 per 100,000 — roughly double the national rate of ~14. Montana, Alaska, New Mexico, Idaho, and South Dakota cluster right behind. Because these states have small populations, the exact #1 spot shuffles year to year, so researchers usually talk about the region rather than a single state — the Mountain West is often called the "suicide belt."

What researchers point to

Firearm access and lethality. This is the factor with the strongest evidence. Suicide attempts with a firearm are fatal roughly 85–90% of the time, versus a few percent for most other methods. The Mountain West has the nation's highest household gun ownership, and guns there are more often stored loaded and unlocked. Since many attempts are impulsive and crises are short-lived, the availability of a highly lethal method converts attempts into deaths. States with high gun ownership don't have notably more attempts — they have more deaths.

Rurality and access to care. Low population density means social isolation, long travel times to emergency care, and severe shortages of psychiatrists and counselors — many frontier counties have none. Rural EMS response times also reduce the chance of surviving an attempt.

Cultural norms. Ethnographic and survey work describes a self-reliance and stoicism ethic ("cowboy up") that discourages help-seeking, compounded by small-town concerns about privacy and stigma in places where the local clinician is also your neighbor.

Demographics and occupations. The region skews toward middle-aged and older white men — the highest-risk demographic nationally — and has high concentrations of veterans and of occupations with elevated suicide rates: mining, oil and gas extraction, construction, agriculture, logging. Boom-and-bust extractive economies add financial volatility.

Alcohol and substance use. Heavy drinking rates are high in the region and alcohol is a well-documented risk factor for impulsive attempts.

Native American and Alaska Native communities. These populations have the highest suicide rates of any racial/ethnic group in the US, tied to historical trauma, forced displacement, poverty, and underfunded health services. This weighs heavily in Alaska, New Mexico, South Dakota, and Montana.

The altitude hypothesis. A genuinely interesting and still-unsettled line of research, led largely by groups at the University of Utah (Perry Renshaw, Brent Kious, and colleagues). Suicide rates correlate with mean county elevation even after controlling for gun ownership, income, population density, and race. The proposed mechanism is chronic mild hypobaric hypoxia altering brain serotonin synthesis and bioenergetics, worsening mood disorders. Skeptics argue the correlation may still reflect unmeasured confounding with rurality and culture. Notably, altitude doesn't seem to track with depression rates the same way, which complicates the story.

Most researchers treat this as multiplicative rather than a single cause: a high-risk population, in isolated places with thin mental health infrastructure, with easy access to the most lethal method available.
