Guns per 100 residents: 31.8
Culture: Until 2002, all you needed was a national ID card to purchase a gun in Uruguay, the most firearm-friendly country in Latin America. In the late 1990s, landowners in neighboring Brazil, which has much stricter laws, began amassing personal arsenals to protect themselves from gangs by doing their shopping across the border. In 2002, Uruguay instituted much tougher licensing requirements and began cracking down on illegal firearms.
Nevertheless, Uruguayans remain attached to their arms. According to the Interior Ministry's own statistics, the country has about 600,000 registered gun owners and about an equal number of unregistered weapons. Overall, the country is ranked as one of the most stable in Latin America, but its rate of gun homicide is one of the world's highest, just behind the United States.
For now, Uruguay is the only Latin American country in Small Arms Survey's top 10, but thanks to the flow of weapons to drug cartels from the United States, Mexico may soon be joining it.
