Yep. It’s an American problem.

I think it’s wrong to generalize such a huge country with very varying local legistlation and people. Would be nice to see a state by state comparison.
Last major state-by-state analysis (Household Gun Ownership Gun Death Rate Per 100,000) gives these top five and bottom five states (first number is gun ownership percent, second is death rate, they are ranked by the latter):
1 Louisiana 45.6 percent 18.91
2 Mississippi 54.3 percent 17.80
3 Alaska 60.6 percent 17.41
4 Wyoming 62.8 percent 16.92
5 Montana 61.4 percent 16.74
50 Rhode Island 13.3 percent 3.14
49 Hawaii 9.7 percent 3.56
48 Massachusetts 12.8 percent 3.84
47 New York 18.1 percent 5.11
46 New Jersey 11.3 percent 5.46
The problem with doing per-state analysis in the US is that while each state sets its own laws, all states have open borders with each other. So gun availability in California is directly affected by laws in Nevada, etc. Not to mention city ordinances, where the restrictions are so localized that there can’t be any significant effect. Alaska and Hawaii may be the only two states without this issue clouding the stats. But then all of these statistics include suicides (which I think is appropriate, but you have to be aware of this), and Alaska and Wyoming have rather obscene suicide rates (27 and 28 per 100,000, while the national average is 12.6).
EDIT: Finland, with the highest suicide rate of all those listed countries, sits at 14.2, Sweden is at 12.7, and the rest have lower suicide rates than the US. The US is really not so great in the suicide department.
