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.[1] 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.[2] It is also the basis for other terrorism-related databases, such as the Global Terrorism Index (GTI) published by the Institute for Economics and Peace.[3]
