The list obtained from the Seguridad Justicia y Paz website. In the methodology, the report mentions that the major difficulty when obtaining data for the ranking was the lack of transparency from many countries in the list. It also states that Mexico has replaced Brazil by having the most dangerous cities in the world now, despite the fact that Brazil has 67% more citizens than Mexico.

The report discusses cities that are included in the ranking for the first time and cities that have moved out of the list, as well.
