Guns per 100 residents: 37.8
The culture: The high number of unregistered and illegal guns floating around Serbia and the western Balkans is an unfortunate legacy of the conflicts that have racked the region since the early 1990s. During the communist era, Yugoslavia was a major international exporter of cheap infantry weapons.
During the years of fighting, nearly everyone in the conflict area had a weapon in the house. Despite government collection efforts since the war, there are still an estimated 900,000 unregistered weapons in Serbia. The former Yugoslav region's flourishing black market for weapons made it a popular source for organized criminal organizations and militant groups in Western Europe during the 1990s. Experts worry that arms dealers there might now be supplying terrorists.
Serbia today has relatively restrictive gun ownership laws. Citizens are not permitted to own automatic or semiautomatic weapons, and registration -- including background checks and safety training -- is required for all gun owners. Nonetheless, black-market AK-47s are reportedly still fairly easy to come by.
