"Despite public anxiety about extremists inspired by Al Qaeda and the Islamic State, the number of violent plots by such individuals has remained very low. Since 9/11, an average of nine American Muslims per year have been involved in an average of six terrorism-related plots against targets in the United States. Most were disrupted, but the 20 plots that were carried out accounted for 50 fatalities over the past 13 and a half years.
In contrast, right-wing extremists averaged 337 attacks per year in the decade after 9/11, causing a total of 254 fatalities, according to a study by Arie Perliger, a professor at the United States Military Academy’s Combating Terrorism Center. The toll has increased since the study was released in 2012."
