Key Findings:
The Berman Jewish DataBank Current Jewish Population Report originates from the American Jewish Year Book article by Sergio DellaPergola, World Jewish Population 2019, regarding the worldwide study of Jewish demography.
In his article, Sergio DellaPergola defines four major concepts in order to study scientifically the demography of contemporary world Jewry, including the core Jewish population (CJP)—the group who consider Judaism their identity. DellaPergola's core Jewish population includes Jewish-only individuals: (a) those who define themselves as Jewish by religion and (b) those who define themselves as Jewish although not based on religion - but also do not have another religion with which they identify. The broadest of these conceptualizations of Jewish includes those eligible for Israel’s Law of Return.
At the beginning of 2019, DellaPergola estimates the world Core Jewish population to be 14,707,400, which is an increase of 100,000 (0.69%) over the revised 2018 estimate of 14,606,500. Since the world's total population increased by 1.11% in 2018, DellaPergola notes that world Jewry continued to increase at a lower rate than the general world population (Jewish world population growth was approximately 62% of the rate of world population growth).
DellaPergola estimates the 2019 core Jewish population in the United States to be approximately 5,700,000 and for Israel to have a Jewish population of 6,665,600 core Jews. More specifically, the number of Jews in Israel increased from the revised 6,554,500 in 2018 to 6,665,600 at the beginning of 2019, an increase of 111,100, or 1.70%. In contrast, the estimated Jewish population in the Diaspora decreased from the revised 8,052,000 to 8,041,800—a decrease of 10,200, or -0.13%.
Methodology:
"World Jewish Population, 2019" is published as number 26, Current Jewish Population Reports series of the Berman Jewish DataBank at The Jewish Federations of North America. It derives from Chapter 8 of the American Jewish Year Book, 2019.
DellaPergola notes the challenges of data consistency, given the different legal systems and organizational provisions under which Jewish communities operate in different countries. In spite of diligent efforts to create a unified analytic framework for Jewish population studies, data users should be aware of these difficulties and of the inherent limitations of Jewish population estimates.
