Wyoming has generally had the highest age-adjusted suicide rate in recent CDC data — roughly 30 per 100,000 people, about double the national rate (~14). The exact ranking shifts year to year among a small cluster of states: Montana, Alaska, and New Mexico trade places with Wyoming at the top, and because these states have small populations, their rates are statistically noisy from year to year.

More robust than any single state's ranking is the regional pattern: the Intermountain West and Alaska form what researchers call the "suicide belt," while the Northeast (New Jersey, New York, Massachusetts) has the lowest rates.

Commonly cited explanations:

Firearm access. This is the factor with the strongest evidence. Wyoming, Montana, Alaska, and Idaho have among the highest household gun ownership rates in the country. Suicide attempts are often impulsive, and firearms are lethal in roughly 85–90% of attempts versus a few percent for most other methods — so access to a highly lethal means converts crises into deaths. Firearms account for a majority of suicides in these states.

Rurality and health care access. Low population density means social isolation, long distances to emergency care, slower EMS response, and severe mental health provider shortages — many frontier counties have no psychiatrist at all.

Demographics. These states have large shares of middle-aged and older white men, the highest-risk demographic nationally. Several also have substantial American Indian and Alaska Native populations, who experience very high rates tied to historical trauma, displacement, poverty, and substance use.

Cultural norms. Ethnographic and survey work points to strong self-reliance and stoicism norms in the Mountain West, which discourage help-seeking and increase stigma around mental health treatment.

Occupational and economic factors. Mining, oil and gas extraction, agriculture, and construction all carry elevated suicide rates — associated with boom-bust income volatility, transient workforces, physical injury, chronic pain, and opioid use.

Alcohol use. The Mountain West and Alaska report some of the highest binge-drinking rates nationally; alcohol is a major acute risk factor.

Veteran population. These states have high per-capita veteran populations, and veteran suicide rates exceed civilian rates.

Altitude (contested). Researchers including Perry Renshaw at the University of Utah have found that county-level mean elevation correlates with suicide rates even after controlling for gun ownership, poverty, and population density. The proposed mechanism is that chronic mild hypoxia at altitude impairs serotonin synthesis and brain bioenergetics. This remains a genuinely open question — critics argue it's hard to fully separate altitude from the rural, cultural, and firearm variables it travels with.

Seasonal light (Alaska specifically). Extreme photoperiod variation and long winter darkness are often invoked for Alaska, though the seasonal pattern of suicides doesn't map onto this as cleanly as one might expect.

Most researchers treat this as multi-causal, with firearm prevalence and rurality doing the heaviest explanatory work.
