ISIS in America

From Retweets to Raqqa

The Report

Released in December 2015, our report, ISIS in America: From Retweets to Raqqa, consists of two parts. The first examines all cases of United States persons arrested, indicted or convicted in the U.S. for Islamic State-related activities. A wide array of legal documents provides empirical evidence for identifying several demographic factors related to the arrested individuals. This section also looks at the cases of Americans who, while not in the legal system, are known to have engaged in IS-inspired behavior.

In the second part, we examine IS-related mobilization in America. The 71 individuals studied in our report defy any cookie-cutter profile of the “American IS supporter.” As such, we analyze the individual motivations of IS supporters; the role of the Internet, specifically social media, in the radicalization and recruitment process; whether radicalization took place in isolation or with other like-minded individuals; and the degree of their tangible links to IS.
