>In 2023, domestic extremists killed at least 17 people in the U.S., in seven separate incidents. This represents a sharp decrease from the 27 extremist-related murders ADL has documented for 2022—which itself was a decrease from the 35 identified in 2021. It continues a trend of fewer extremist-related killings after a five-year span of 47-79 extremist-related murders per year (2015-2019). One reason for the trend is the decrease in recent years of extremist-related killings by domestic Islamist extremists and left-wing extremists.
