ADL H.E.A.T Map
ADL H.E.A.T. Map is the first-of-its-kind interactive and customizable map detailing extremist and anti-Semitic incidents around the nation. ADL experts in its Center on Extremism developed this unique visualization with data points extracted from information sources including news and media reports, government documents (including police reports), victim reports, extremist-related sources, Center on Extremism investigations and more.
Filter data sets and learn more about hate, extremism, anti-Semitism and terrorism in your area and around the country.
Note: “Anti-Semitic Incidents” is a separate dataset whose results are not filterable by ideology. For a full thematic analysis of anti-Semitic incidents, including the ideology of the perpetrators, please see ADL’s annual Audit of Anti-Semitic Incidents.
When interacting with a specific incident or city, clicking on the state will zoom you out to view state-level incidents. From here, clicking on the state again will allow you to view nationwide incidents.
When filtering data, a unique URL is updated to reflect your filtered data set. This makes it convenient to share a specific filtered view by using the unique link on social media and beyond e.g. “Extremist Murders in Denver, CO fueled by Islamist ideology."
Below the map there is a table of incidents. This changes when you filter by State or City, Incident Type, Ideology and Years. You can click on the “i” icon next to each filter drop-down menu for more information – including what defines each incident, ideology and years contained.
Each data set reflects different time periods of collected data. Click on the “i” icon next to each filter drop-down menu for more information.
FREQUENTLY ASKED QUESTIONS
1. Why is [Incident X] not included in the map?
Incidents may be excluded from the map for all sorts of reasons, including because the incident in question may not actually be extremist-related. Many hate crime murders, for example, have no connection to white supremacy or other form of extremism. If you think we have overlooked an incident, you may contact us to provide relevant details. Report an Anti-Semitic, Bias or Discriminatory Incident on ADL’s incident reporting form. To share data sets, please contact firstname.lastname@example.org.
2. Why are certain map categories tracked for many years, while other categories only go back a few years?
There are date limitations on certain types of map data in large part because older data is sometimes unavailable and/or doesn’t comply with our reporting requirements. The Center on Extremism plans to periodically update all map categories with additional incidents.
3. Why do you not include the location of hate groups and other extremist groups on the map?
The membership of most extremist groups draws from fairly wide geographic areas that cannot be accurately represented by a single point on a map. Often the self-stated location of a group is nothing more than a P.O. Box or the residence of the group’s leader, while the members of the group may be spread out over dozens or even hundreds of miles. Other groups exist primarily online with no real-world geographical focus.
