Guns per Capita and Homicides – Is There a Correlation?

Metin's Media & Math

Here’s a statistics quicky. A while ago, just after the tragic shooting at Sandy Hook Elementary School, I wanted to produce a clear proof that gun ownership and homicide rates are correlated. It seemed logical to me that, plus / minus statistical fluctuations, the phrase “more guns, more violence” holds true. So I extracted the relevant data for all first world countries from Wikipedia and did the plot. Here’s the picture I got:

Maybe you are as surprised as I was. Obviously, there’s no relationship between the two variables, more guns does not mean more violence and less guns does not mean less violence. So whatever the main cause for the violence problem in the US (see the isolated dot in the top right? That’s the US), it can’t be guns. And that’s a liberal European speaking …

Just in case anyone cares, I blame the gang and hip-hop culture…
