There's a correlation because people who live in dangerous places tend to carry guns. But that's not causation--there's no reason to suspect that carrying a gun increases my chances of being killed by a gun.
Huh? Surely carrying a gun somewhere where there are no other guns immensely increased the chance that you’ll be killed by a gun, since the number of guns in the vicinity went from zero to one.
It does, yes. The majority of firearm deaths in the US are suicides, and the majority of suicides are committed with a firearm. The suicide rate is several times higher among men who own guns or regularly handle guns than it is among men who do not. It's clear that gun ownership has a high propensity to convert a survivable mental health crisis into a suicide. A US adult (but especially a man) who owns a gun is far more likely over their lifetime to use the gun on themself than they are to use it to defend themself.
Yes, I suppose it necessarily does, although I was referring more to the chance that in a struggle (perhaps an attempted robbery) your gun accidentally or intentionally discharges.
