Project description

This web site shows how drug trafficking works in El Salvador.
The data analysis allowed identifying the different ports of entry of each drug: cocaine, marijuana, crack and heroin.
The design of the web site is designed for millennial users, with striking illustrations and short texts. At the end, an interactive map with the amounts of drugs seized in each department and municipality of El Salvador is offered from 2011 to 2017.

What makes this project innovative?

It was designed so that mobile phone users could navigate in each of the stories about each type of drug. In addition, a map was redrawn showing how El Salvador is just a place of passage for boats and other maritime means used by traffickers. This is the firts time than we use an interactive map disigned by or ingeneer.

What was the impact of your project? How did you measure it?

The web site was shared 932 times on Facebook. Between June 18, 2018 and April 6, 2019, this site has had 22,068 page views; 18,270 unique page views; and an average time on page of 2:52 minutes.

Source and methodology

We wanted to make a drug map similar to what Ojo Público did in Peru. The first thing we did was to review what had been published before about drug trafficking in El Salvador. Then, the police were asked to register drug seizures by municipality and department, type of drug and place of seizure (air, land or maritime). The police sent a messy database that had to be cleaned with Python. Once the database was standardized, a visual analysis was carried out. This allowed us to identify that for each type of drug there was a different entry route: cocaine arrives by sea, heroin by the airport and marihuana by land, from Guatemala.

Technologies Used

Data cleaning was done with Python. The interactive map was done with Javascript. The analysis of the data with Tableau Public. The data visualizations were made with Infogram.
