With nearly 6.5 million Jews, Israel is the only Jewish-majority and explicitly Jewish state.
In 1939, the core Jewish population reached its historical peak of 17 million. Due to the Holocaust, the number was reduced to 11 million by 1945. The population grew to around 13 million by the 1970s and then recorded near-zero growth until around 2005, due to low fertility rates and assimilation. From 2005 to 2018, the world’s Jewish population grew on average 0.63% annually (while the world population grew 1.1% annually in the same period). This increase primarily reflected the rapid growth of Haredi and some Orthodox sectors, who are becoming a growing proportion of Jews.
