A full one-third of global homicides occur in Latin America, even though the region has just 8% of the world's population, according to UN data.

Drug trafficking, gang wars, political instability, corruption, and poverty contribute to the region's elevated violence.

The council's ranking includes cities with a population of more than 300,000 and doesn't count deaths in combat zones or cities with unavailable data, so some dangerous cities might not be represented on the list.
