Claude on Question 20, Oct 2

Wyoming and Montana consistently trade places at the top, with Alaska close behind. Recent CDC figures put Wyoming's age-adjusted rate around 29–32 per 100,000, roughly double the national rate of about 14 per 100,000. (Because these states have small populations, year-to-year rankings bounce around, so "highest" depends on the specific year — it's more accurate to say the Mountain West and Alaska form a consistent high-rate cluster, sometimes called the "suicide belt.")

Researchers point to several overlapping factors rather than a single cause:

Firearm access. These states have among the highest household gun-ownership rates in the country, and firearms account for roughly two-thirds to three-quarters of suicides there versus about 55% nationally. Because firearm attempts are lethal in ~85–90% of cases, the same number of attempts produces far more deaths. This is generally considered the single largest contributor.

Rurality and health care access. Low population density means long distances to care, widespread mental-health provider shortages, fewer crisis services, and slower emergency response.

Demographics. The highest-risk group nationally is middle-aged and older white men, who are overrepresented in these states. These states also have large American Indian/Alaska Native populations, which experience much higher suicide rates — driven by historical trauma, poverty, and limited services — and unusually high shares of military veterans.

Occupation and economy. Mining, oil and gas extraction, agriculture, ranching, and construction all have elevated suicide rates, linked to injury and chronic pain, boom-and-bust income volatility, and transient workforces.

Culture. Norms of self-reliance and stoicism, plus stigma around seeking mental health help, are frequently cited in qualitative research.

Altitude. A more debated hypothesis: studies (notably Brenner et al. 2011, and work by Perry Renshaw's group) found county-level suicide rates correlate with elevation even after controlling for gun ownership, income, and population density. The proposed mechanism is that chronic mild hypoxia affects serotonin synthesis and brain bioenergetics. Intriguingly, all-cause mortality is lower at altitude, which argues against pure confounding — but the finding remains contested and isn't considered settled.

Alcohol and substance use. Heavy drinking and methamphetamine use rates are above average in much of the region.

For current numbers, CDC WONDER and WISQARS are the authoritative sources, since my figures may be a year or two behind.
