In the presentation “U.S. Jewry 2010: Estimates of the Size and Characteristics of the Population,” given at the Association for Jewish Studies meeting in Boston on December 20th, Professor Leonard Saxe reported that rather than declining, the Jewish population has been increasing since 1990. NJPS 2000-01, the last national Jewish population study sponsored by the United Jewish Communities (currently, the Jewish Federations of North America), found that the U.S. Jewish population had declined by 300,000 during the 1990-2000 period. Saxe and his colleagues found that the Jewish population has actually risen from about 5.5 million individuals in 1990 to an estimated 6.5 million as of 2010, an increase of nearly 20%.
