Wyoming generally has the highest suicide rate in the US — roughly 30 per 100,000 people in recent CDC data, more than double the national rate of about 14 per 100,000. Montana and Alaska trade places with it at the top depending on the year; because these states have small populations, their rates bounce around year to year, so the "#1" designation isn't very stable. What is stable is the regional pattern: the highest rates cluster in the Mountain West and Alaska, a region sometimes called the "suicide belt," while the lowest rates are in the Northeast (New Jersey, New York, Massachusetts) and Washington, DC.

Researchers point to a combination of overlapping factors rather than any single cause:

Firearm access. 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. Because firearm attempts are lethal roughly 85–90% of the time versus a few percent for most other methods, availability of a highly lethal means during a short-lived crisis strongly predicts completed suicide. This is considered one of the most robust explanations.

Rurality and isolation. Low population density means social isolation, long distances to emergency and psychiatric care, and slower response times — all of which reduce the chance of surviving an attempt or getting help beforehand.

Mental health care shortages. Much of the Mountain West is designated as a mental health professional shortage area, with few psychiatrists per capita and limited inpatient capacity.

Demographics. These states skew toward the highest-risk group: middle-aged and older white men. Several also have substantial American Indian/Alaska Native populations, among whom suicide rates — especially for young people — are extremely high, which researchers link to poverty, historical trauma, and displacement. Western states also have high veteran populations per capita.

Cultural norms. Self-reliance, stoicism, and stigma around help-seeking are frequently cited, though these are harder to measure than the structural factors.

Occupational and economic factors. Mining, oil and gas extraction, construction, agriculture, and forestry all carry elevated suicide rates, and boom-bust resource economies create financial instability.

Altitude. A more contested line of research, associated with Perry Renshaw, Brent Kious, and colleagues at the University of Utah, finds that county-level elevation correlates with suicide rates even after controlling for gun ownership, rurality, income, and access to care. The proposed mechanism is that chronic mild hypoxia interferes with serotonin synthesis and brain bioenergetics. This hypothesis remains debated and obviously can't explain Alaska, where the leading environmental candidate is extreme seasonal variation in daylight.

Most epidemiologists would say the altitude question is interesting but secondary; the consensus emphasis falls on means availability, isolation, care access, and demographic composition.
