Record and prevent: How Mexico is fighting crime with the help of maps

In Mexico, alarming security issues are nothing new — press reports, statistics and general public perception all point to a rise in criminal offenses. Faced with this situation, which has at times exceeded the scope of the public institutions meant to deal with it, regular citizens in Mexico City have turned to mapping technology in an effort to reduce the impact of crime in their communities.

According to a report on criminal offenses in the capital, in the second quarter of 2018, Mexico City suffered from the second highest incidents of violent robbery in the nation. It also ranked third out of 32 states for street robberies and tenth for burglary. These statistics translate to an astounding 96 violent robberies, 27 vehicle thefts, 20 burglaries, 44 business robberies and 40 robberies per day.

In response to this rise in crime, a group of community members from Anáhuac in Mexico City have created a public Google map where people can record the exact spots where crimes have taken place. The goal of the map is to record and to prevent robberies and vehicle theft. Users can also leave details about the crimes and help civil organizations with the collection of statistics.

The data is based on reports by either witnesses or victims themselves. Some of the reports seen in the map have been previously reported to the corresponding authorities as well. The link to the map is shared on Twitter, where community members can also ask questions and discuss the ongoing urban violence:

The strategy of using geographic location apps as a tool to combat crime is not a new phenomenon. From 2013 to 2016, the website Hoyo de Crimen (Hole of Crime) gathered information about all types of crime per city block. Data on criminal incidents was obtained through information requests from the Mexican capital's security services. This particular project included recorded events such as assaults, vehicle theft and homicides, among others. The project was created by programmer Diego Valles and continued by Carlos Castañeda, who wrote about it on u-GOB, a site devoted to the use of technology in governance. In Castañeda's post, Valles comments on how his project can help people avoid danger in the city:

Despite the relevance of such a project, Hoyo de Crimen was ultimately forced to stop updating information after authorities refused to provide necessary data and disseminate official information.

Maps for every kind of crime
 

Geography students at the National Autonomous University of Mexico (UNAM), have also adopted the map initiative to follow and denounce crime inside the campus. The data is collected through an anonymous online survey which is shared publicly on Facebook. In a post on Facebook, one student explains that the survey and the map aim to “show the spaces taken over by violence in the university campus”. The post also makes reference to student shock groups, also known as porros, who have been the at the center of allegations of violence inside pacific protests for years at UNAM.

Architecture students in the same university have also drawn up a map to locate assaults, harassment allegations and other acts of violence happening inside the campus. The group shares information on Facebook and Instagram:

Mapping initiatives in Mexico have not just been limited to to assaults on pedestrians or vehicle thefts. Since 2016, a female developer working under a pseudonym for her own safety has produced an interactive map of femicides in the whole country.

The development and spread of mapping technologies have proven to be an important tool to combat crime and, more importantly, to create a self-reliant community which aims to collect data provided by users themselves.
