Claude on Question 20, Sep 16

Wyoming has typically ranked highest in recent years, with an age-adjusted rate around 30 per 100,000 — roughly double the national rate of about 14 per 100,000. Montana and Alaska trade places with it at the top depending on the year, followed by New Mexico, Idaho, South Dakota, and Nevada. Because these states have small populations, their rates are statistically volatile and the exact ranking shifts year to year; the broader and more stable pattern is that the Mountain West and Alaska form what researchers call the "suicide belt."

Commonly cited contributing factors:

Firearm access. This is the explanation with the strongest evidence. Firearms are involved in a majority of suicides in these states (often 60–70%, vs. about 55% nationally), and they are far more lethal than other methods — roughly 90% of attempts with a gun are fatal, compared to a small fraction for overdose. High household gun ownership combined with practices like storing guns loaded and unlocked means that impulsive crises are more likely to end in death. Research on "means restriction" suggests this alone accounts for a large share of the regional gap.

Rurality and isolation. Low population density means long travel distances to emergency and psychiatric care, fewer crisis services, and greater social isolation. Many rural counties have no practicing psychiatrist at all, and hospital and clinic closures have worsened this.

Demographics. The highest-risk group nationally is middle-aged and older white men, who make up a large share of these states' populations. Several of these states also have substantial American Indian and Alaska Native populations, which face very high rates tied to historical trauma, poverty, and limited services. These states also have among the highest concentrations of veterans.

Occupation and economics. Mining, oil and gas extraction, agriculture, ranching, construction, and logging all have elevated suicide rates. Boom-bust resource economies add financial instability, and work in these fields is associated with injury, chronic pain, and opioid use.

Culture and help-seeking. Norms of self-reliance and stigma around mental health treatment are frequently invoked, though this is harder to measure than the other factors and rests on softer evidence.

Altitude. A more contested hypothesis, advanced by researchers including Perry Renshaw and Brent Kious at the University of Utah, holds that chronic mild hypoxia at high elevation alters serotonin synthesis and brain energy metabolism in ways that worsen depression. The correlation between elevation and suicide rate is strong and persists in some analyses after controlling for gun ownership, poverty, and rurality. Critics argue the remaining confounding is hard to rule out, since altitude correlates with so many other regional features. It's taken seriously but not settled.

Most researchers treat this as a convergence of factors rather than a single cause — high-risk demographics and occupations, thin healthcare infrastructure, and widespread access to highly lethal means all overlapping in the same geography.
