The Migrants' Files

Data-driven investigation

How many migrants and refugees died in their attempt to reach Europe in recent years? In addressing this crucial issue, in 2014 Dataninja produced "The Migrants’ Files", its first International inquiry that received a Data Journalism Award.

Initially based on data gathered by Gabriele Del Grande and available on his blog FortressEurope, our team produced a series of visualizations and an interactive mapping of this situation in Italy (later published by Wired Italy and Le Monde).

A follow-up addressed the larger trend of migrant waves in EU, with an in-depth inquiry produced in collaboration Nicolas Kayser-Bril and Journalism++ (Berlin) and sponsored by a JournalismFund grant. A second edition focused on costs incurred by EU countries to monitor their borders against the trafficking of human beings.

Findings and data of this project has been variously published by several EU media outlets, including Le Monde, l’Espresso, Liberation,, Vice News, Suddeutsche Zeitung, Information, El Confidential,, Sydsvenskan,, Visao, Cesky rozhlas, Gazeta, BIQDATA, and others.
