How many Jews are intermarried?

According to a 1990 Jewish Population Survey, the most recent numbers available, there are 720,000 interfaith married couples. Given that this survey was twelve years ago, the number is likely to be higher, at around 1,000,000 intermarried couples. According to the 1990 survey, 28% of the 2.6 million married Jews in the U.S. are married to non-Jews and the rate of intermarriage was 52% of all marriages involving at least one Jew.
