ADL H.E.A.T. Map™ FAQ

  • August 7, 2018

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 adlmedia@adl.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.

4. What information sources do you use to track these incidents?

Information sources vary depending on the type of incident, but collectively include news and media reports, government documents (including police reports), victim reports, extremist-related sources and Center on Extremism investigations. 

5. What do I do if I know of a possible anti-Semitic incident or other incident of the sort that you track on your map?

Contact ADL to report an anti-Semitic or other bias incident here. Contact adlmedia@adl.org to report some other sort of incident represented on the map.

6. Are you interested in collaborating on other data for the map?

Yes. We are committed to expanding the scope of the data in future iterations through partnerships.
