Global Terrorism Database

The Global Terrorism Database (GTD) is a database of terrorist incidents from 1970 onward. As of May 2021, the list extended through 2019 recording over 200,000 incidents, although data from 1993 is excluded. The database is maintained by the National Consortium for the Study of Terrorism and Responses to Terrorism (START) at the University of Maryland, College Park in the United States. It is also the basis for other terrorism-related measures, such as the Global Terrorism Index (GTI) published by the Institute for Economics and Peace.
