This study examines whether characteristics of U.S. counties can explain the geographic clustering of terrorist attacks in the United States from 1990-2010. It builds upon data from a previous study (LaFree and Bersani, 2012) that examined the connection between the distribution of terrorism and the distribution of ordinary crimes over nearly four decades.
