Times of Israel: According to the Jewish Agency for Israel, the number of Jews worldwide stands at approximately 15.2 million, compared to 15.1 million in 5781. In 1939, the global population of Jewish people reached 16.6 million, and shortly thereafter that population was decimated by the Nazis and their European henchmen from France, Holland and Belgium in the West to Poland, the Baltic States, and Ukraine in the East. In six years, the worldwide Jewish population had fallen by more than a third.
“For from the top of the rocks I see him,
And from the hills I behold him;
There! A people dwelling alone,
Not reckoning itself among the nations.” Numbers 23:9
The number of Jews in Israel is close to 6.9 million (compared to 6.8 million in 5781), while about 8.3 million live outside Israel (including around 6 million in the United States). The updated estimates by Professor Sergio Della Pergola of the Hebrew University of Jerusalem will be published in the American Jewish Year Book 2021.
