The U.S. has more guns per capita—about nine guns for every ten people—than any other country. It has nearly twice as many guns per capita as Yemen, which ranks second. The U.S. also ranks first in total number of guns, with 270 million of them privately owned. The second highest total is in India, which has 46 million guns—and a population three times that of the United States. The U.S. ranks second only to Mexico in its gun-related murder rate. Mexico’s gun-related murder rate is driven by drug wars (Washington Post, December 15).
