Global Terrorism Database ISIL Auxiliary Dataset

The complex evolution and affiliations of the organization currently known as the Islamic State of Iraq and the Levant (ISIL) presents challenges for systematic, comprehensive analysis of terrorist attacks carried out by ISIL and related groups and individuals. In order to facilitate analysis of the Global Terrorism Database (GTD) with respect to ISIL-related terrorism, the GTD team conducted supplemental research to generate this auxiliary dataset that identifies ISIL related attacks worldwide from 2002 through 2016 and classifies them based on the type of relationship the perpetrators of each event had to ISIL.
