U.S. Jewish Population?
What is the approximate Jewish population in the United States?
According to the Jewish Virtual Library, there were an estimated 6,452,030 Jewish people in the United States in 2006 (the most recent data available), which is more than there were in any other country. (Israel came in second.) This represents approximately 2.2% of the total U.S. population.
The same site has a chart of the state-by-state breakdown of the Jewish population, revealing that New York had both the highest number (1,618,320) and highest percentage (8.4%) of Jews in the country, by a wide margin.
