Leonard Saxe (who "took sociology to the max" this year - along with BJPA director Steven M. Cohen)  released his 2010 report on American Jewry. Some highlights:

  • Reform and Orthodox-raised Jews are most likely to retain their denomination identity as adults
  • There are 6,466,899 American Jews, an increase of about one million since 1990.
  • 77% of American male Jews have had a bar mitzvah. 43% of female Jews have had a bat mitzvah.
  • Younger Jews (18-29) are the least likely to label themselves "Jewish not by religion".

 Compare with, for example, Statistics of Jews 1899-1900, which reports that the US Jewish population increased from 3,000 in 1818 to 937,800 in 1897.

Sergio DellaPergola's 2010 World Jewish Population estimate is out too:

At the beginning of 2010, the world’s Jewish population was estimated at 13,428,300—an increase of 80,300 (0.6 percent) over the 2009 revised estimate. The world's total population increased by 1.25 percent in 2009. World Jewry hence increased at half the general population growth rate.
