I live in Las Vegas and can offer some insight.
We get some visitors that come with intent to commit suicide and want "a last harrah" excitement.
We have loose gun laws still, only recently shifting to Democrat tightening laws. Anyone can still get a gun at a gun show.
We have lots of alcohol consumption by visitors.
The suicide rate is over residents as denominator.
There are many people of low income here, not very happy about life.
The heat could definitely affect attitudes.
But, it is true that Indeed, researchers found that residents of Las Vegas had a 50 percent higher risk of suicide than folks living elsewhere in the country.
"Residents of Las Vegas who leave Las Vegas — that is, they take some kind of hiatus or break from Las Vegas, they go out of the county — their risk for suicide goes down," he said.
Visitors have an even higher rate.
Rapid growth in population of LasVegas can lead to a lot of social isolation and a lack of community cohesiveness. Although this might explain the elevated suicide risk among residents, it doesn't explain the even higher suicide rate among visitors to Vegas.
The economic downturn of 2008-2009 definitely had an effect.
They don't have all of the answers, but there are explanations.
Very few are about a large loss of money,, but that happens also.
