Antisemitism in the United States has existed for centuries. In the United States, most Jewish community relations agencies draw distinctions between antisemitism, which is measured in terms of attitudes and behaviors, and the security and status of American Jews, which are both measured by the occurrence of specific incidents. FBI data shows that in every year since 1991, Jews were the most frequent victims of religiously motivated hate crimes, according to a report which was published by the Anti-Defamation League in 2019. Evidence suggests that the true number of hate crimes against Jews is underreported, as is the case for many other targeted groups.
