Alternative Scales of Extremism: The Relationship Between Scale and Predictive Measures of Extremism in the United States

This report investigates spatial patterns of terrorism and targeted violence in the United States. Such investigations are rare because terrorist attacks are rare in the United States compared to other nations and the terrorist attacks that do occur are dispersed in similar patterns as population centers. In sum, the relative rarity of attacks, the geographic size of the United States, and the distribution of population density create inherent challenges historically. However, the recent outbreak of political violence throughout the United States coupled with advances in spatial statistics creates an opportunity to investigate emerging patterns at subnational scales.
