Wyoming generally ranks highest, with Montana and Alaska close behind — the three trade places depending on the year. Wyoming's age-adjusted rate has run around 30–32 per 100,000, roughly four times that of the lowest-ranking states (New Jersey, New York, and Massachusetts, all around 7–8 per 100,000). Because these states have small populations, year-to-year rankings are statistically noisy, so researchers usually talk about the broader pattern: a cluster of high-rate states across the Intermountain West and northern Plains, sometimes called the "suicide belt."

Factors researchers point to:

Firearm access. This is the most consistently supported explanation. The Mountain West has the nation's highest rates of household gun ownership, and firearms are by far the most lethal method — about 85–90% of attempts are fatal, versus a small fraction for most others. Since many suicidal crises are short-lived, access to a highly lethal method at the wrong moment substantially raises the chance an attempt ends in death. Studies controlling for other variables repeatedly find state-level gun ownership tracks with suicide rates, driven almost entirely by firearm suicides.

Rurality and isolation. Low population density means weaker social connection, longer travel to care, and slower emergency response.

Mental health care shortages. Many counties in these states have no practicing psychiatrist, and crisis services and inpatient beds are scarce.

Demographics and occupation. These states skew toward working-age men, who die by suicide at about four times the rate of women. They also have large American Indian and Alaska Native populations, which face among the highest rates of any U.S. group, and economies built on mining, oil and gas, agriculture, and construction — industries with elevated suicide rates and boom-bust instability.

Culture and stigma. A strong ethic of self-reliance is often cited as discouraging help-seeking, though this is harder to measure than the other factors.

Altitude. A more contested hypothesis, advanced notably by Perry Renshaw and colleagues at the University of Utah, holds that chronic mild hypoxia at elevation disrupts serotonin synthesis and brain bioenergetics. Altitude does correlate with suicide rates even after adjusting for gun ownership, income, and population density, but critics argue the correlation may reflect unmeasured regional confounders rather than a physiological mechanism.

Most epidemiologists treat this as multi-causal: the West combines several independent risk factors at once, which is why the regional pattern has persisted for decades.
