These are some of the findings of the new Pew Research Center survey, conducted Feb. 20-June 13, 2013, among a nationally representative sample of U.S. Jews. This is the most comprehensive national survey of the Jewish population since the 2000-2001 National Jewish Population Survey. More than 70,000 screening interviews were conducted to identify Jewish respondents in all 50 states and the District of Columbia. Longer interviews were completed with 3,475 Jews, including 2,786 Jews by religion and 689 Jews of no religion.
