and an ardent supporter of that version of a peace process. Demographics As of 2020, the American Jewish population is, depending on the method of identification, either the largest in the world, or the second-largest in the world (after Israel). Precise population figures vary depending on whether Jews are accounted for based on halakhic considerations, or secular, political and ancestral identification factors. There were about four million adherents of Judaism in the U.S. as of 2001, approximately 1.4% of the US population. According to the Jewish Agency, for the year 2017 Israel was home to 6.5 million Jews (49.3% of the world's Jewish population), while the United States contained 5.3 million (40.2%). According to Gallup and Pew Research Center findings, "at maximum 2.2% of the U.S. adult population has some basis for Jewish self-identification." In 2020, it was estimated by demographers Arnold Dashefsky & Ira M. Sheskin in the American Jewish Yearbook that the American Jewish population totaled 7.15 million, making up 2.17% of the country's 329.5 million inhabitants. In 2012, demographers estimated the core American Jewish population (including religious and non-religious) to be 5,425,000 (or 1.73% of the US population in 2012), citing methodological failures in the previous higher estimates. Other sources say the number is around 6.5 million. The American Jewish Yearbook population survey had placed the number of American Jews at 6.4 million, or approximately 2.1% of the total population. This figure is significantly higher than the previous large scale survey estimate, conducted by the 2000–2001 National Jewish Population estimates, which estimated 5.2 million Jews. A 2007 study released by the Steinhardt Social Research Institute (SSRI) at Brandeis University presents evidence to suggest that both these figures may be underestimations with a potential 7.0–7.4 million Americans of Jewish descent. Those higher estimates were however arrived at by including all non-Jewish family members and household members, rather than surveyed individuals. In a 2019 study by Jews of Color Initiative it was found that approximately 12-15% of Jews in the United States, about 1,000,000 of 7,200,000 identify as multiracial and Jews of color. The population of Americans of Jewish descent is demographically characterized by an aging population composition and low fertility rates significantly below generational replacement. The National Jewish Population Survey of 1990 asked 4.5 million adult Jews to identify their denomination. The national total showed 38% were affiliated with the Reform tradition, 35% were Conservative, 6% were Orthodox,
