The collection of open source data on violent extremism and terrorism has revolutionized our understanding of the characteristics and complexities of violent political action. For the past 16 years, Dr. LaFree has been closely connected with two of the largest efforts to collect and analyze open source data on terrorism: the Global Terrorism Database (GTD) and the Profiles of Radicalization in the United States (PIRUS) data. The GTD begins with a universe of over 1.6 million articles published daily worldwide in order to identify the relatively small subset of articles that describe terrorist attacks.
Dr. LaFree’s team of researchers convert this pipeline into an unclassified matrix which describes the characteristics of worldwide attacks from 1970 to the present. The PIRUS data are instead limited to terrorist attacks against the United States and include individual level data on about 1,800 individuals who have been associated with acts of illegal political extremism. Dr. LaFree’s presentation will focus on what these two unclassified data bases can tell us about the nature of the terrorist threat to the United States and the world.
This symposium is part of our Homeland Security Symposium Series focused on addressing supplemental educational/training needs with different homeland security enterprise related domains requested by our stakeholders. This endeavor is funded by the DHS Science and Technology Directorate, Office of University Programs, under the Borders, Trade, and Immigration Institute. There are no attendance fees associated with this symposium. Attendees or their respective agencies are responsible for applicable travel costs.
