The Terrorism and Extremist Violence in the United States (TEVUS) Database and Portal is based on four related open-source databases. The portal compiles behavioral, geographic, and temporal characteristics of extremist violence in the United States dating back to 1970. Through the portal, users are able to build search queries based on four data types including specific events, perpetrators of an act of terrorism or an extremist crime, groups, and/or court cases related to terrorism and extremist crime in the United States.
TEVUS is intended for a wide audience including members of media, academia, private sector security professionals, law enforcement and intelligence analysts. Anyone can request access to the TEVUS Portal by completing the online TEVUS Portal Access Request Form.

is led by researchers at the Terrorism Research Center at the University of Arkansas. The ATS is an empirical relational database consisting of data on federal terrorism-related court cases, persons indicted in these court cases, and related officially designated terrorism incidents. Included in the TEVUS portal are data from court case, person, organization, affiliation, incident, and precursor activity (antecedent) tables in the ATS. Variables included cover demographic information, terrorist group to which the individual belongs, and temporal and geospatial data on incidents and antecedent activities. Additional ATS data not accessible via the TEVUS portal include variables covering prosecution and defense data, count/case outcome, sentencing data as well as additional variables that further type and describe the indictees, perpetrators, incidents, and antecedent activities. Questions related to the ATS data should be directed to firstname.lastname@example.org. For more information about the ATS please visit the Terrorism Research Center’s website: http://www.trc.uark.edu.
is led by START researchers at the University of Maryland. The GTD is an open-source database that includes information on terrorist attacks around the world. It is comprised of systematic data on domestic as well as international terrorist attacks. Only attacks that occurred in the United States are included in the TEVUS portal. For more information and access to the full dataset, visit the GTD website: http://www.start.umd.edu/gtd/about/.
is compiled by researchers located at Michigan State University, John Jay College, Indiana University - Purdue University, Indianapolis, and Seattle University. The ECDB is a relational database that includes information on all publicly known violent and financial crimes committed in the United States by extremists associated with al-Qa’ida and its associated movement (AQAM) - which for the purpose of this dataset also include crimes committed by extremists associated with the Islamic State of Iraq and the Levant (ISIL), the violent Far Right (FR), and the Animal and Earth Liberation Fronts (ELF and ALF).

is led by START researchers at the University of Maryland. PPT-US is a group-level dataset, including information on the background, ideology, structure, goals, and activities of groups and organizations identified as perpetrators of attacks in the Global Terrorism Database (GTD). Only GTD perpetrator groups for which there is high confidence of responsibility for at least one violent attack are included in PPT-US.
