Each year, ADL (Anti-Defamation League) tracks incidents of anti-Semitic harassment, vandalism and assault in the United States. Since 1979 we have published this information in an annual Audit of Anti-Semitic Incidents.
In 2023, ADL tabulated 8,873 anti-Semitic incidents across the United States. This represents a 140% increase from the 3,698 incidents recorded in 2022 and is the highest number on record since ADL began tracking anti-Semitic incidents in 1979. In fact, ADL tracked more incidents in 2023 than in the previous three years combined.
Incidents increased in all major Audit categories. Assault incidents increased by 45% to 161 incidents, vandalism increased 69% to 2,177 incidents and harassment increased 184% to 6,535 incidents.
The dramatic increase in incidents took place primarily in the period following the October 7 terrorist attacks in Israel. Between October 7 and the end of 2023, ADL tabulated 5,204 incidents -- more than the incident total for the whole of 2022. Fifty-two percent of the incidents after October 7 (2,718) included references to Israel, Zionism or Palestine.
However, even prior to October 7, there were monthly increases in February (402), March (471), April (432), May (437) and September (513). Each of these months broke the prior record for most incidents recorded in a single month, set in November 2022 (394).
After October 7, ADL observed explicitly anti-Semitic and anti-Zionist rhetoric at 1,352 anti-Israel rallies across the United States. Leaving out all Israel-related incidents, anti-Semitic incidents still rose by 65% to 5,711 over the 3,457 non-Israel-related incidents recorded in 2022.
Anti-Semitic incidents also increased year-over-year in all major location categories. Incidents at K-12 schools increased by 135% to 1,162 incidents. Incidents at Jewish institutions jumped by 237% to 1,987, driven mostly by massive waves of hoax threats directed at synagogues and other institutions in the summer, fall and winter. And incidents on college and university campuses spiked by a staggering 321% to 922 incidents, most of which occurred after the October 7 terrorist attacks.
ADL’s 2023 Audit numbers contain 1,350 incidents included due to a post-October 7 methodology update. Excluding incidents included under the methodology update, ADL tabulated 7,523 incidents, a 103% increase in anti-Semitic incidents from the incident total in 2022.

In response to the historic rise in anti-Semitic incidents, ADL urges Members of Congress to cosponsor and pass the Countering Antisemitism Act and Governor and state leaders to create and adopt State Strategies to Counter Antisemitism following the framework of the U.S. National Strategy to Counter Antisemitism.
