Wyoming has consistently ranked highest in recent years, with an age-adjusted suicide rate of roughly 30 per 100,000 — more than double the national rate of about 14 per 100,000. Montana, Alaska, New Mexico, and Idaho typically round out the top five, though the exact order shifts year to year (these are small-population states, so rates are statistically volatile).

This clustering in the Intermountain West is well enough established that researchers call it the "suicide belt." The main explanatory factors:

Firearm access. This is the factor most researchers weight most heavily. Wyoming, Montana, Idaho, and Alaska have among the highest household gun ownership rates in the country, and firearms account for a disproportionate share of suicides there. Because firearm attempts are lethal in roughly 85–90% of cases — versus under 5% for most other methods — access to a gun converts more crises into deaths, even where the underlying rate of suicidal ideation is similar.

Rurality and geographic isolation. Low population density means fewer social connections, longer distances to emergency and psychiatric care, and slower response times. Many Western counties have no practicing psychiatrist at all.

Mental health care shortages. These states rank poorly on provider density, insurance coverage, and crisis infrastructure.

Cultural norms. A strong ethos of self-reliance and stoicism is thought to suppress help-seeking, compounded by stigma in small communities where anonymity is hard.

Demographics and occupation. These states skew toward middle-aged and older white men — the highest-risk demographic nationally — and have large veteran populations. Extractive and agricultural industries (mining, oil and gas, ranching, construction, commercial fishing) carry elevated risk, partly through injury, chronic pain, and boom-bust economic instability.

Native American and Alaska Native populations. AI/AN communities have the highest suicide rates of any US racial or ethnic group, driven by historical trauma, displacement, poverty, and underfunded health services. This is significant in Alaska, New Mexico, Montana, and the Dakotas.

Altitude. A more contested hypothesis, associated with Perry Renshaw and colleagues at the University of Utah, holds that chronic mild hypoxia at high elevation impairs serotonin synthesis and brain bioenergetics, worsening mood disorders. Studies find altitude correlates with suicide rates even after controlling for gun ownership, income, and rurality — but critics argue residual confounding is hard to rule out, since altitude tracks closely with rurality and gun prevalence in the US.

Most researchers treat this as multi-causal rather than attributable to any single driver, with firearm availability and care access doing the most explanatory work.
