RAND Tracks Worldwide Terrorism Attacks in New Database Project

The RAND Corporation recently released an update regarding its Worldwide Terrorism Incident Database. "On March 31, 2008, support for development and dissemination of the Worldwide Terrorism Incident Database lapsed, causing the Memorial Institute for the Prevention of Terrorism to remove web-based search of that database from its website. Since then, RAND has received many requests for access to the data. RAND is exploring options for making the data available on a subscription basis. The RWTID includes two RAND databases, the RAND Terrorism Chronology Database and the RAND-MIPT Terrorism Incident Database. The RAND Terrorism Chronology Database records international terrorist incidents that occurred between 1968 and 1997, while the RAND-MIPT Terrorism Incident Database records domestic and international terrorist incidents from 1998 to the present. The following article, "Understanding the Terrorism Database," was published in the MIPT Quarterly Bulletin, first quarter 2002 ( The bulletin provides additional information about how the Database works, as well as selected statistics from 2001." according to the RAND website.
