Global Terrorism Database Available Online
Information on 80,000 domestic and international terrorist events from 1970 through 2007.
The National Consortium for the Study of Terrorism and Responses to Terrorism (START) -- a Homeland Security center of excellence at the University of Maryland -- has posted a Global Terrorism Database (GTD) online. The database is open-source and includes information on 80,000 domestic and international terrorist events from 1970 through 2007. For each incident, information is available on the date and location, weapons used, nature of the target, number of casualties, and -- when identifiable -- the group or individual responsible. The site is the most comprehensive unclassified database on terrorist events, according to a statement on the site.
