The two largest Jewish communities in the world exist in Israel (6.7M) and the US (5.7M). Other significant Jewish populations include Canada’s 390k and European Jews (1.5M)—France (450k), the UK (295k), Russia (165k) and Germany (120k). Latin America’s Jews live throughout the region, with Argentina (200k), Brazil (50k) and Mexico (40k) being amongst the largest communities. In 1921, on the dawn of the British Mandate for Palestine (and two decades before the Holocaust), there were roughly 15.7M Jews in the world, more than in 2021.
