Online antisemitism in numbers
The latest figures we found, each with its year, source and what exactly was measured. We do not merge numbers from different methods. Last updated: October 2026.

What the numbers do not say
There is no single global count of antisemitic content online. Each body measures something different: posts, reports or incidents, on different platforms and in different languages.
The gap between hundreds of thousands of posts a day and a handful of reports a day in each country shows that most of this content never reaches anyone who records it.
How we choose figures
Only from sources anyone can open and check, with a year and a method. Government figures, or figures whose method was not published, are labelled as such. We update them when new reports come out.
