U.S. most armed country with 90 guns per 100 people

Well, 90% isn't bad, I guess. This surprised me, though:

India had the world's second-largest civilian gun arsenal, with an estimated 46 million firearms outside law enforcement and the military, though this represented just four guns per 100 people there. China, ranked third with 40 million privately held guns, had 3 firearms per 100 people.
