Extremist Crime Database Related Projects

Project Details


The Extremist Crime Database was created by Joshua Freilich and Steven Chermak to better understand extremist crime in the United States. The national database first included information on the perpetrators, victims, event, and group characteristics of crimes committed by members of the domestic far-right, but has since been expanded to include information on crimes by the far-left, religious extremists and single-issue extremists.  

The Extremist Crime Database is part of the Terrorism and Extremist Violence in the U.S. (TEVUS) database.
