Using a leaked database from 2016 on Islamic State recruits, we were able to geographically locate where almost 600 recruits originated from in Tunisia—one of the highest exporters of foreign fighters to Syria. We then used socio-economic data from Tunisian delegations (the equivalent of a district or a county—the smallest geographic unit that could be measured) to try to find what was driving foreign fighters to go to Syria.
Surprisingly, our research suggests that absolute indicators of well-being, which are intuitively linked to terrorism by many policymakers, are not related to a higher probability of joining a violent extremist group.
