Suicide seems to be highest in rural (lonely) cold (also less sunlight) states.

> cold (also less sunlight)

Yeah, this is also consistent with northern Europe and its higher suicide rates in cold, long, and dark winters. There's definitely a correlation between sun exposure and suicide, while it's not the only factor.

For the "lonely" hypothesis, this map is not precise enough to confirm it. You would probably need a map with dots representing the exact location of all suicides on the map, and overlay it with a density map to see if there is a proper correlation or not.

I think suicide is prevented by HIV – the two maps seem to be nearly complete opposites.

HIV correlates with sexual activity, which seems likely to have a negative correlation with suicide. People who are getting laid are happier.

I wouldn't say that. People who are in steady relationships are happier, and those have less HIV risk.

People who bounce for person to person might be having fun, but long term and not usually happier.
