The Anti-Defamation League (ADL) Center on Extremism (COE) works to identify and track domestic extremist-related murders and since 2015, has used its data to release annual reports that examine the loss of human life due to extreme movements and ideologies. The latest report, Murder & Extremism in the United States in 2022, provides an in-depth look at the deadly threat of domestic extremists in our nation.

Some Key Findings from the report:

• In 2022, domestic extremists killed at least 25 people in the U.S., in 12 separate incidents.
• 21 of the 25 were linked to white supremacists, which was unusually high and primarily due to mass shootings.
• The issue of extremist-related mass killings is of growing and special concern in the report due to the increase of such events over the past decade.

ADL acknowledges that the statistics in this report are just one metric of extremist violence and offers, as a resource for further information, its regularly updated Hate, Extremism, Antisemitism and Terrorism (H.E.A.T.) Map, which details specific incidents by state and nationwide. The report also contains a section detailing ADL’s PROTECT Plan--a comprehensive, seven-part plan to address the threat of domestic extremism and domestic terrorism.
