In 1939, the core Jewish population reached its historical peak of 17 million (0.8% of the global population). Because of the Holocaust, the number was reduced to 11 million in 1945.[6] The population grew again to around 13 million by the 1970s, but has since recorded near-zero growth until around 2005 due to low fertility rates and to assimilation. Since 2005, the world's Jewish population has been growing modestly at a rate of around 0.78% (in 2013). This increase primarily reflects the rapid growth of Haredi and some Orthodox sectors, who are becoming a growing proportion of Jews.[7]
