Isis in five charts
At last count, most 'western' Isis fighters hailed from France or Britain
But the most common nationality for foreign Isis fighters is Tunisian
According to the most recent data, there are more pro-Isis tweeters in Saudi Arabia (even against Syria and Iraq)
Western countries tend to be the most concerned about Islamic extremism
Even though, according to 2013 data, countries outside Europe are by far more likely to experience terrorism-related deaths
With thanks to Statista for all charts
