U.S. civilians alone account for 393 million (about 46 percent) of the worldwide total of civilian held firearms. This amounts to "120.5 firearms for every 100 residents."
According to the report, the world's armed forces control about 133 million (about 13 percent) of the global total of small arms, of which over 43 percent belong to two countries: the Russian Federation (30.3 million) and China (27.5 million). And, the world's law enforcement agencies control about 23 million (about 2 percent) of the global total of small arms.
