More guns means more gun violence. It’s an intuitive relationship — so why can’t we seem to grasp it?

This world map, created by Reddit user phillybdizzle using 2012 data from The Guardian, shows just how high the rate of firearm ownership is in America — 88.8 guns per 100 people, by far the highest rate on the planet. (The second-highest, Yemen, has 54.8 guns per 100 people.)

The study behind it: Two Harvard researchers looked at 26 high-income countries and compared firearm ownership to homicide rates. The U.S. leads all developed countries in both categories — an American is 20 times more likely to die by gunshot than a resident of another developed country.
