As many of you know, in the gvSIG Association we have an open source software solution for the analysis and management of information related to crime and citizen security, gvSIG Crime. One of the technologies used in gvSIG Crime is gvSIG Online, that allows to generate geoportals, as simple or complex as we need, among many other things.

Precisely with gvSIG Online we have created a simple map viewer that allows us to visualize the 50 most dangerous cities in the world based on the homicide rate in the last year (2017).

Without a doubt, it is striking that 47 cities of these 50 cities are located in America, and 42 in Latin America.

The information presented is drawn from the last report of the Citizen Council for Public Safety and Criminal Justice (CCSPJP – Consejo Ciudadano para la Seguridad Pública y la Justicia Penal), a Mexican civil organization that generates the list of the 50 most dangerous cities in the world every year. For this report, which annually is an international reference, the CCSPJP uses a simple methodology, comparing the number of homicides per 100,000 inhabitants. They include only those cities that exceed 300,000 inhabitants and compute only intentional homicides or deaths due to aggression. The areas where there is a war conflict are excluded.

The data is extracted by combining several sources: journalistic information, official lists of governments and local authorities, reports from international organizations and NGOs.

Through this geoportal you can visualize the cities, request information about each of them on the number and annual homicide rate, consult the attribute table and search.

Here you have the video about the map and how the geoportal works:

Finally we take the opportunity to announce that we will publish a free course about gvSIG Desktop applied to criminology. Pay attention if you are interested in this issue…
