People comparing Gun violence in USA to less population dense countries like Australia and Canada is ridiculous.
It be like me taking a single state and comparing it with them. In fact lets do just that.
Iowa- 90,000 guns /100,000 people, .71 murder/ 100,000 = 126,760 guns per murder
Canada- 30,800 guns/ 100,000, .38/ 100,000= 81,052 guns per murder
Australia - 21,000 guns/ 100,000, .16/100,000= 131,250 guns per murder
Looks like more guns don't always equal more violence, and this is with proximity to more dangerous states unlike Australia. Still we could take it a step further since Iowa is a lot more population dense then these ridiculously small population densities of Canada and Australia.
Iowa- 55person/Sqmi
Australia - 8.3
Canada- 10.2
But I don't feel like doing more calculations, it would be too easy.
In short, pretty uncomparable, we can skew stats all we like to paint a better narrative.
Also I feel like this only gets talked about so often is because everything in USA gets on the media, but a lot of things in other countries are simply ignored.
Disclaimer: Stats may not be perfect or completely correct, and could be outdated, but you get the point.
