70-80% of all firearm deaths in the US are suicide related.
Closer to 66%,
https://everytownresearch.org/gun-violence-america/ Nearly two-thirds of gun deaths are suicides.5 The U.S. gun suicide rate is eight times that of other high-income countries.6 Access to a gun increases the risk of death by suicide by three times.7 Gun suicides are concentrated in states with high rates of gun ownership.8 Most people who attempt suicide do not die—unless they use a gun. Across all suicide attempts not involving a firearm, less than five percent will result in death.9 But for gun suicides, those statistics are flipped: approximately 85 percent of gun suicide attempts end in death
The US owns 40% of guns in the world. 4% of the world's population. Yet only 3.7% of homicides.
Lots of the murders in Brazil are firearms related and it has very strong gun-control laws. The average citizen is not allowed to own a gun.
Yet mass shootings are becoming dramatically more common.
What I find curious is that while the Brazilian murder rate is about 6 or 7 times that in the US, the rate of firearm related deaths is 'only' double. Is firearm suicide dramatically more common in the US, or are a lot of the murders perpetrated in Brazil not firearm related? It just seems odd.
