The number of antisemitic incidents more than doubled in 2023, surging after the Hamas attack on Israel on Oct. 7, according to the Anti-Defamation League’s annual audit, which pointed out that more than half of last year’s incidents took place in the last three months of the year.

The report, published in early April, tabulated 8,873 incidents in 2023, 5,204 of them occurring after Oct. 7. By contrast, the League tallied 3,697 in 2022. Incidents included assaults, vandalism, harassment, and painted swastikas. Ten percent of the incidents in 2022 happened on college campuses.

ADL researchers compiled the data using information from victims, law enforcement, the media and partner organizations.
