The Mexico-based Citizen’s Council for Public Security and Criminal Justice recently released the new ranking for the world’s most violent cities. The new rankings reflect data on homicide for cities which have a population of at least 300,000. Death in combat zones and those in cities with unavailable data are not included. Additionally, about one-third of the world’s homicides happened in Latin America. This is a significant number since according to UN data, only 8% of the world’s population live in the region. The reason cited for the large percentage of deaths was due to poverty, drug trafficking, gang wars, corruption and political instability. The following is the listing of the 20 most dangerous cities in the world.
