The number of Jews in the U.S. now comes to just under six and a half million (6,401,000), of which only 4,223,000 are Jews according to halacha. In other words, 2.2 million people who consider themselves Jewish are not Jewish according to halacha, as a result of the alarming intermarriage rate caused primarily by the Reform and Conservative movements.
This disturbing statistic was revealed at the Knesset Subcommittee on Israel and Diaspora Affairs, which runs in tandem with the Immigration, Absorption and Diaspora Affairs Committee. The committee focused on social and demographic trends within U.S. Jewry.
On another matter, Professor Theodore Sasson of Brandeis University reported that in 12 years monetary support for Israel among American Jews doubled. While in 1994 $1.08 billion was given annually to Jewish institutions and organizations in Israel, in 2007 U.S. Jews donated $2.1 billion. Of that amount, $150 million went to Torah-based education, $500 million was donated to the Jewish Agency, $400 million to secular education, $300 million to medicine, $100 million to art and culture institutions and $50 million was donated to settlement in Judea and Samaria. A similar amount was donated to left-wing organizations in Israel.
