In this study two-step cluster analysis was used in an exploratory effort to try and determine what the primary typologies of terrorism are in the United States based on the profiles of individual terrorist who operated in the United States from 1948 – 2016. From this, it was discovered that terrorists in the United States can be classified into two overarching typologies. The first one can most appropriately be called political extremism and the second typology may be titled religious extremism. These findings suggest that terrorists have varying characteristics in accordance with which typology they are classified by. Moreover, this study also found that terrorists share some common characteristics that make them unique among other types of social deviants.
