Jewish population by country

As of 2023, the world's core Jewish population (those identifying as Jews above all else) was estimated at 15.7 million, 0.2% of the 8 billion worldwide population. Israel hosts the largest core Jewish population in the world with 7.2 million, followed by the United States with 6.3 million. Other countries with core Jewish populations above 100,000 include France (440,000), Canada (398,000), the United Kingdom (312,000), Argentina (171,000), Russia (132,000), Germany (125,000), and Australia (117,200). The number of Jews worldwide rises to 18 million with the addition of the "connected" Jewish population, including those who say they are partly Jewish or that have Jewish backgrounds from at least one Jewish parent, and rises again to 21 million with the addition of the "enlarged" Jewish population, including those who say they have Jewish backgrounds but no Jewish parents and all non-Jewish household members who live with Jews. Counting all those who are eligible for Israeli citizenship under Israel's Law of Return, in addition to Israeli Jews, raised the total to 25.5 million.

Two countries account for 81% of those recognised as Jews or of sufficient Jewish ancestry to be eligible for citizenship in Israel under its Law of Return: the United States with 51% and Israel with 30% (including the West Bank with 2%). An additional 16% is split between France (3%), Canada (3%), Russia (3%), the United Kingdom (2%), Argentina (1%), Germany (1%), Ukraine (1%), Brazil (1%), Australia (1%), and Hungary (1%), while the remaining 3% are spread around approximately 98 other countries and territories with less than 0.5% each. With over 7 million Jews, Israel is the only Jewish-majority country and the only explicitly Jewish state.

In 1939, the core Jewish population reached its historical peak of 17 million. Due to the murder of approximately six million Jews during the Holocaust, this number was reduced to 11 million by 1945. The population grew to around 13 million by the 1970s and then recorded almost no growth until around 2005, due to low fertility rates and assimilation of Jews. From 2005 to 2018, the world's Jewish population grew 0.63% annually on average, while world population overall grew 1.1% annually in the same period. This increase primarily reflected the rapid growth of Haredi and some Orthodox sectors, who remain a growing proportion of Jews.
