You can view the report at this link, and the recording of this event at this link. If you have any questions, please email the START events team at start-events@umd.edu.

The GTD is the most comprehensive unclassified database of terrorist attacks in the world, and the 2020 update includes details of more than 200,000 events that took place worldwide over 50 years, from 1970 to 2019. The GTD research team combines artificial intelligence and analysis by experienced researchers to systematically identify violent events that meet the definition of terrorism and record a wide range of information about each event. The database, which is sourced by news media articles published around the world, includes more than 100 variables documenting the date, location, weapons, tactics, targets, perpetrators, and casualties and outcomes of each attack.

Dr. Erin Miller is the program manager for the Global Terrorism Database (GTD) at START headquarters at the University of Maryland, where she has been part of the GTD team since 2004. Her roles have included improving the consistency of the data and adding key variables to the database, developing efficient and effective data collection strategies and training, and producing accessible analysis that provides context for current events in terrorism and counter-terrorism. She frequently consults with users of the database, including researchers, policy makers, analysts, journalists, and students. For six years, Miller authored the Statistical Annex for the U.S. State Department’s Country Reports on Terrorism (2012--2017). She has served as principal investigator on a number of START research projects related to the GTD, including the Terrorism and Extremist Violence in the United States (TEVUS) platform, the Profiles of Perpetrators of Terrorism in the United States (PPT-US) database, and the Program to Prepare Communities for Complex Coordinated Terrorist Attacks.
