Extremism in the United States

Despite fears that extremism is on the rise in the United States, right-wing extremism is far more prevalent than jihadi terrorism. From 2014 to 2023, 19 percent of extremist-related killings were caused by someone affiliated with Islamist extremism, while 76 percent of extremist-related killings were carried out by someone affiliated with right-wing extremism.
