This report examines all jihadist-motivated terrorist attacks carried out in Europe and North America since the declaration of the Caliphate by the Islamic State group in June 2014. By analyzing the 51 attacks and their perpetrators, this study constitutes the first comprehensive account of attacks carried out during the past three years.

While there has been a relative surge in the number of U.S. persons radicalized and recruited by the Islamic State in the last five years, other jihadist organizations, primarily al-Qaeda, remain popular and active. This suggests that, while group affiliation matters, the draw of the wider Salafi-jihadist ideology that al-Qaeda, IS, and other like-minded groups adhere to is equally important when analyzing the jihadist threat to America.

The self-proclaimed Islamic State and other jihadist actors have identified several unique roles for Western women in their radicalization and recruitment efforts. This report finds that, while few conduct violent plots, many disseminate propaganda, donate resources, or travel abroad to offer their support. This report uses a wealth of primary and secondary data to examine the efforts of 25 jihadi women in America from January 2011 to September 2016.

The report consists of two parts. The first examines all cases of U.S. persons arrested, indicted, or convicted in the United States for IS-related activities. This section also looks at the cases of other Americans who, while not in the legal system, are known to have engaged in IS-inspired behavior.
The second examines various aspects of the IS-related mobilization in America. It analyzes the individual motivations of IS supporters, the role of the Internet—in particular, social media—in their radicalization and recruitment processes, whether their radicalization took place in isolation or with like-minded individuals, and the degree of their tangible links to IS.
