GENEVA (Reuters) - The United States has 90 guns for every 100 citizens, making it the most heavily armed society in the world, a report released on Tuesday said.
U.S. citizens own 270 million of the world's 875 million known firearms, according to the Small Arms Survey 2007 by the Geneva-based Graduate Institute of International Studies.
About 4.5 million of the 8 million new guns manufactured worldwide each year are purchased in the United States, it said.
"There is roughly one firearm for every seven people worldwide. Without the United States, though, this drops to about one firearm per 10 people," it said.
On a per-capita basis, Yemen had the second most heavily armed citizenry behind the United States, with 61 guns per 100 people, followed by Finland with 56, Switzerland with 46, Iraq with 39 and Serbia with 38.
