The Global Terrorism Database is the most comprehensive unclassified database of terrorist attacks in the world. The GTD is produced by a multi-disciplinary team of researchers at the National Consortium for the Study of Terrorism and Responses to Terrorism (START) at the University of Maryland, applying fundamentals of social sciences and computer and information sciences. It documents domestic and international terrorist attacks around the world since 1970, and contains more than 190,000 records. For each event, the database includes available details on more than 100 variables — the date and location of the attack, the weapons used, information about the target, the number of casualties, and the group or individual responsible. START makes the GTD publicly available in order to familiarize analysts, policymakers, scholars, and journalists with patterns of terrorism and increase understanding of terrorist violence.
The GTD provides baseline data on violent deaths due to terrorist attacks around the world — a critical component of the registry of violent deaths. The GTD research team at START has more than 50 years of experience collecting the GTD, combining artificial and human intelligence. GTD researchers contribute insight on best practices, challenges, and opportunities to improve systematic event data collection to advance the GReVD consortium’s efforts.
