The RAND Database of Worldwide Terrorism Incidents (RDWTI)

Last updated: 12/17/2024

The RAND Database of Worldwide Terrorism Incidents (RDWTI) is a compilation of data from 1968 through 2009. This legacy RAND project developed and maintained a database of terrorism incidents stretching back to 1968, which provides comprehensive information on international and domestic terrorism. Over the years, many public and private sponsors have contributed to the maintenance of the RDWTI and its predecessors, the RAND Terrorism Chronology and the RAND-MIPT Terrorism Incident Database. With over 40,000 incidents of terrorism coded and detailed, the quality and completeness of the RDWTI was remarkable for its time. RAND staff conducted extensive research on candidate terrorist attacks, drawing on staff with regional expertise, relevant language skills, and in-country field work experience. The database is free and publically accessible for research and analysis. However, please attribute all use of the data to the RAND Database of Worldwide Terrorism Incidents. The RAND database covers the time period from 1968 through 2009. Data for 2009 are not available for some areas; see the Research Coverage page for a full list.
