Gun death rate? That's so non-specific lol so what? This is the percentage of deaths caused by guns vs other causes? The percentage of times a shooting results in a death? Violent crimes only? Suicides included? Defensive shootings? Police shootings? Let's see large metro areas and population centers instead of states for comparison. I'm pretty sure Wyoming could only be that high because of suicide.
Edit: found the CNN article. The map does include suicides.
