The share of Americans killed by guns is without parallel in the developed world. The most striking statistic: 87 percent of children killed by guns in 23 of the world's most developed, wealthiest countries were Americans.
That comes from a 2011 analysis of 2003 mortality data from members of the Organization for Economic Cooperation and Development, a group of wealthy, developed nations. It found that in general, Americans were killed by guns far more frequently than people in the other 22 countries, including Australia, Canada, the United Kingdom, France, and Hungary. They were also more likely to be killed, period: The American homicide rate was seven times the rate of the other 22 countries.
The other findings underscore, in the wake of the San Bernardino massacre, that this is a uniquely American problem:
Regardless of whether mass killings like the one in San Bernardino are becoming more frequent, they happen far more in the US than anywhere else.
