The short answer

Wyoming has typically ranked highest in recent years, with an age-adjusted suicide rate around 30+ per 100,000 people — roughly double the national rate of about 14 per 100,000. Montana, Alaska, and New Mexico trade places with it near the top, and the exact ranking shifts year to year because these states have small populations, so rates are statistically noisy.

More broadly, researchers talk about a "suicide belt" spanning the Intermountain West and Alaska — Wyoming, Montana, Idaho, Utah, Nevada, New Mexico, Colorado, and the Dakotas all cluster well above the national average.

What researchers point to

Firearm access. This is the factor with the strongest evidence. Suicide attempts with firearms are fatal roughly 85–90% of the time, versus a small fraction for most other methods. Wyoming, Montana, Alaska, and Idaho have among the highest household gun-ownership rates in the country, and firearms account for a majority of suicides there. Since many suicidal crises are short-lived, the lethality of the means available matters enormously.

Rural isolation and thin health infrastructure. Low population density means long drives to care, few psychiatric beds, chronic mental-health provider shortages, and slower emergency response times. Social isolation itself is also a risk factor.

Demographics. These states skew toward the highest-risk group in U.S. data: middle-aged and older white men. They also have high per-capita veteran populations, and veterans have elevated suicide rates. In Alaska, the Dakotas, Montana, and New Mexico, high rates among American Indian and Alaska Native communities — linked by researchers to historical trauma, dispossession, poverty, and underfunded health services — also contribute, particularly among youth.

Occupation and economy. Mining, oil and gas, agriculture, ranching, and construction all show elevated suicide rates. Boom-bust extractive economies add financial instability.

Culture and help-seeking. Norms emphasizing self-reliance and stoicism, plus stigma in small communities where anonymity is hard, are thought to reduce willingness to seek treatment.

Alcohol and substance use. Heavy drinking rates are high in several of these states, and intoxication is a significant factor in impulsive attempts.

Altitude (contested). A line of research — notably from groups at the University of Utah — has found that suicide rates correlate with elevation even after controlling for gun ownership, income, and rurality. The proposed mechanism is that chronic mild hypoxia affects serotonin synthesis and brain energy metabolism, worsening mood. It's a genuinely interesting hypothesis but remains debated, since altitude correlates with many other things and the causal evidence is largely ecological rather than experimental.

A caveat on interpretation

Most of this evidence is correlational and at the state level, which makes it vulnerable to the ecological fallacy — patterns across states don't necessarily hold for individuals. Firearm access is the factor where individual-level and natural-experiment evidence is strongest; the rest are plausible contributors of uncertain relative weight.

The CDC's WISQARS database and WONDER tool are good places to look at the underlying numbers directly if you want current figures.
