> This retrospective study examines 20 yr of county-specific mortality data from 1979 to 1998.

I've only read the abstract (so I don't know if my question is answered somewhere in the full report), but does anyone have any insight about why newer data wasn't included in this study?

I recall seeing this article from 2014 referring to suicides in Utah ('utah paradox') and how neuroscientist Perry Renshaw was trying to link it to altitude: http://mic.com/articles/104096/there-s-a-suicide-epidemic-in... which links to another study from 2011: http://ajp.psychiatryonline.org/doi/abs/10.1176/appi.ajp.201...

"Together, the stray statistics and stories about life out west tipped off Renshaw to a common culprit: altitude-induced oxygen depletion. [...] Renshaw believes that oxygen-poor air tampers with brain chemistry, leading to a drop in serotonin and an uptick in dopamine."

From the abstract:

> Controlling for percent of age >50 yr, percent male, percent white, median household income, and population density of each county, the higher-altitude counties had significantly higher suicide rates than the lower-altitude counties. Similar findings were observed for both firearm-related suicides (59% of suicides) and nonfirearm-related suicides.

So (median) income has been considered, in case anyone is wondering.

Altitude as a proxy for isolation, perhaps

> Controlling for... population density of each county,

It's a very weak indicator, I'm living in the densest city I ever lived in and I have less social life than ever.

Random 5 seconds search:

> Follow-up analyses showed there was a significant (p = .005) relationship between population density and isolation in Whites, Hispanics, and others, in that higher population density was associated with greater social isolation.

In any case it's much more complex than "many people = no one feels alone"

Also if you compare the "suicide by county" and "distance to nearest metro area" map there is a very nice overlap:

I don't want to come of as flippant, but I'm genuinely curious: Is there a correlation to how many stories the person's residence has as well? If they live on a 3rd story of an apartment, is there a higher suicide rate than the first floor of an apartment?
