**Wyoming** typically has the highest suicide rate in the US, at roughly 30–32 deaths per 100,000 people in recent CDC data — about double the national rate of ~14 per 100,000. Montana, Alaska, New Mexico, Idaho, and South Dakota cluster right behind it. Because these are small-population states, the exact rank shifts year to year; Montana and Alaska have held the top spot in other years.
This cluster of high-rate states in the Intermountain West is sometimes called the "suicide belt." Researchers generally point to a combination of overlapping factors rather than one cause:
**Firearm access.** This is the most robustly supported explanation. The Mountain West has the country's highest household gun-ownership rates, and firearms are lethal in roughly 85–90% of attempts versus far lower rates for most other methods. Since many suicidal crises are short-lived and impulsive, the availability of a highly lethal method converts attempts into deaths. Firearms account for a majority of suicides in these states.
**Rurality and isolation.** Low population density, long distances, harsh winters, and thin social infrastructure contribute to isolation and slow emergency response times.
**Mental health care shortages.** Many of these states have among the fewest psychiatrists and mental health providers per capita, with entire counties lacking any. Distance, cost, and limited crisis services all reduce access.
**Cultural norms around help-seeking.** Researchers often cite a strong ethic of self-reliance and stoicism — sometimes glossed as "cowboy culture" — that stigmatizes asking for help, particularly among men.
**Demographics.** These states skew toward the highest-risk group (middle-aged and older white men) and have large veteran populations per capita. Alaska, Montana, New Mexico, and the Dakotas also have substantial Native American and Alaska Native populations, who experience very high suicide rates linked to poverty, historical trauma, and displacement.
**Economic and occupational stress.** Boom-and-bust extractive industries (mining, oil and gas) and agriculture/ranching are among the occupations with the highest suicide rates, involving financial volatility, physical injury, and social isolation.
**Substance use.** Alcohol misuse rates are elevated in the region and are a well-established risk factor.
**The altitude hypothesis.** A more contested line of research, associated with Perry Renshaw and Brent Kious at the University of Utah, finds that mean county elevation correlates with suicide rates even after controlling for gun ownership, income, rurality, and access to care. The proposed mechanism is chronic mild hypoxia affecting serotonin synthesis and brain bioenergetics. It's a real research literature, not a fringe idea, but it remains unsettled — critics argue residual confounding is hard to rule out.
