Revision History

Antisemitic incidents in the United States hit a record 9,354 in 2024 before declining to 6,274 in 2025, while the UK recorded 3,700 incidents in 2025 — including its first fatal antisemitic terrorist attack in modern history. The surge, triggered largely by the October 7, 2023 Hamas attack, has reshaped Jewish communal life on both sides of the Atlantic, driving $765 million in annual US security spending and prompting governments to announce new counter-antisemitism measures even as debates intensify over how incidents are defined and counted.
