Global Terrorism Database Data Files Now Available through Terrorism and Preparedness Data Resource Center
TPDRC is happy to announce that the data files from the Global Terrorism Database (GTD), the most comprehensive unclassified database of terrorist events in the world, are now available to all users.
These data files contain information on over 80,000 international and domestic terrorist attacks between 1970 and 2004. For each attack, information is provided on:
- date of the event
- type of attack
- weapons used
- target and location
- number of casualties
- group claiming responsibility
- and over 100 other variables.
GTD identifies more than 30,000 bombings, 13,400 assassinations, and 3,200 kidnappings and provides details on more than 1,200 terrorist events within the United States since 1970.
These data were first made available to government officials in 2007, and users can continue to access information about specific events from the GTD Web portal.
The links below direct users to data files, codebooks, and supporting materials for:
GTD1 (cases from 1970 to 1997) (TPDRC Study #22541)
GTD2 (cases from 1998 to 2004) (TPDRC Study #22600)
History of GTD
The Global Terrorism Database--or GTD--began in 2001 when researchers at the University of Maryland obtained a large database originally collected by the Pinkerton Global Intelligence Services. From 1970 to 1997, Pinkerton trained researchers to identify and record terrorism incidents from wire services, government reports, and major international newspapers. With funding from the National Institute of Justice, the Maryland team finished computerizing the original Pinkerton data in December 2005, making corrections and adding information wherever possible. With the launch of the National Consortium for the Study of Terrorism and Responses to Terrorism (START) by the U.S. Department of Homeland Security in 2005, additional funds were made available to conduct validity and reliability checks of the existing data. In April 2006, the Center for Terrorism and Intelligence Studies (CETIS), working directly with START, received additional funding from the Human Factors Division of the Department of Homeland Security to extend the GTD beyond 1997. By May 2008 data collection and coding was completed through 2004. During the next year, data on events after 2004 will be collected, and the new data (1998-present) will be systematically integrated with the original data to form a single source of information on terrorist attacks, from 1970 to early 2008.
