With less than 5 percent of the world's population, the United States is home to roughly 35-50 percent of the world's civilian-owned guns, heavily skewing the global geography of firearms and any relative comparison.
The U.S. also leads wealthy nations in gun homicides, with a rate ten times that of other countries in NATO. This doesn't say much for the NRA's calls for more Americans to arm themselves and their schools in the wake of the Newtown tragedy.
