The most dangerous city in the world varies depending on the source and criteria used. According to a report released by the Citizens’ Council for Public Security and Criminal Justice, Celaya in Mexico ranked as the worlds most dangerous city in 2023 with a homicide rate of 109.4 per 100,000 inhabitants. Another report by the same organization lists Zamora, Mexico as the most violent city in the world in 2023. Tijuana, Mexico is also considered one of the most dangerous cities in the world, with a homicide rate of 105.15 homicides per 100,000 inhabitants. Other sources list different cities as the most dangerous, such as Caracas, Venezuela, Fortaleza and Salvador in Brazil, and St. Louis in the United States. It is important to note that the homicide rate of a city is an imprecise tool for comparison, as the population within city borders may not best represent an urban or metropolitan area with varying rates in different areas.
