Arms and the Man

According to the 2007 Small Arms Survey report by the Geneva-based Graduate Institute of International Studies:
The United States has 90 guns for every 100 citizens, making it the most heavily armed society in the world.
U.S. citizens own 270 million of the world's 875 million known firearms. About 4.5 million of the 8 million new guns manufactured worldwide each year are purchased in the United States.
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.
Germany, France, Pakistan, Mexico, Brazil and Russia were next in the ranking of country's overall civilian gun arsenals.
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.
France, Canada, Sweden, Austria and Germany were next, each with about 30 guns per 100 people, while many poorer countries often associated with violence ranked much lower. Nigeria, for instance, had just one gun per 100 people.
The report, which relied on government data, surveys and media reports to estimate the size of world arsenals, estimated there were 650 million civilian firearms worldwide, and 225 million held by law enforcement and military forces.
Five years ago, the Small Arms Survey had estimated there were a total of 640 million firearms globally.
Only about 12 percent of civilian weapons are thought to be registered with authorities.
