The Global Terrorism Database (GTD) is an open-source database including information on terrorist events around the world from 1970 through 2015 (with additional annual updates planned for the future). Unlike many other event databases, the GTD includes systematic data on domestic as well as transnational and international terrorist incidents that have occurred during this time period and now includes more than 150,000 cases.
