Demographics
The Jewish population of the United States is either the largest in the world, or second to that of Israel, depending on the sources and methods used to measure it.
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 4 million adherents of Judaism in the U.S. as of 2001, approximately 1.4% of the US population. The community self-identifying as Jewish by birth, irrespective of halakhic (unbroken maternal line of Jewish descent or formal Jewish conversion) status, numbers about 7 million, or 2.5% of the US population. According to the Jewish Agency, for the year 2007 Israel is home to 5.4 million Jews (40.9% of the world's Jewish population), while the United States contained 5.3 million (40.2%).
The most recent large scale population survey, released in the 2006 American Jewish Yearbook population survey estimates place 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 of these figures may be underestimations with a potential 7.0–7.4 million Americans of Jewish descent. Jews in the U.S. settled largely in and near the major cities. The Ashkenazi Jews, who are now the vast majority of American Jews, settled first in the Northeast and Midwest cities, but in recent decades increasingly in the South and West. Within the metropolitan areas of New York City, Los Angeles, and Miami lives nearly one quarter of the world's Jews.
