Jewish Intermarriage Statistics

By InterfaithFamily


Spring, 2011

The current intermarriage rate in the Jewish community is 47%. This figure is 10 years old (see below), but it is the most up-to-date figure available. The rest of this document summarizes key statistics related to Jewish intermarriage, with references and links to their sources.

Key Intermarriage Statistics

  •  47% of Jews marrying between 1996 and 2001 married non-Jews[1] .
  • 31% of all married Jews are intermarried.[2 ,3] 
    • 39% of these marriages are Jewish-Catholic[4] .
    • 23% are Jewish-Protestant[5] .
    • 26% are between a Jewish person and a person who doesn’t affiliate with any religion[6] .
  • 33% of children in intermarriages are raised as Jews[7] . The percentage varies greatly by community, however. In Boston, for example, 60% of children of interfaith families are raised as Jews. In Baltimore, 62% of children of intermarriage are raised as Jews. Conversely, in Denver, only 18% are being raised Jewish[8] .
  • 27% of married people in the U.S. are in interfaith marriages. When you count Protestant denominations as different religions, the number jumps to 37%[9] . Roughly 35 million people in the U.S. are in interfaith marriages[10] .


Key Jewish Population Statistics

  • Between 5.2 million[11]  and 6.5 million[12]  Jews live in the U.S. Jews make up roughly 2% of the U.S. population.
  • There are 14.4 million Jews throughout the world. 5.7 million Jews live in Israel. After the U.S. and Israel, the countries with the largest Jewish populations, in descending order, are France, Canada, the United Kingdom, Russia and Argentina. Jews make up .2% of the world population[13] .
  • The metropolitan areas with the largest Jewish populations are, in descending order, Tel Aviv, New York, Jerusalem, Los Angeles, Haifa, South Florida, Beersheba, San Francisco, Paris and Chicago[14] .


Background on Intermarriage in the Jewish Community

For much of American Jewish history, intermarriage was relatively rare. The incidence of intermarriage started to increase in the 1970s (from 13% to 28%). Many Jews know the story of a relative who was disowned (in some cases, mourned as if he or she had died) when he or she married a non-Jew.

In response to the increase in intermarriage, the Reform movement took two controversial steps: it created an outreach department to reach out to and welcome intermarried couples, and decided to recognize the children of Jewish fathers and non-Jewish mothers as Jews (under traditional Jewish law, only children of Jewish mothers are considered Jews).

But when the 1990 National Jewish Population Survey revealed that close to half of all new marriages involving Jews in the previous five years were to non-Jews, intermarriage shot to the top of the Jewish community’s agenda.

Because Judaism doesn’t encourage proselytizing and Jews are such a small minority (somewhere between 5.2 million and 6.5 million), some Jews consider the ongoing high rate of intermarriage a threat to the continued existence of the Jewish people. Major Jewish figures have been harshly critical of intermarriage and view outreach to the intermarried as a waste of limited communal resources. Major Jewish organizations see promoting Jewish in-marriage as one of their explicit or implicit fundamental goals.

In the last two decades, there has been a growing awareness that writing off intermarried families may mean writing off a Jewish future. Intermarriage can be an opportunity to sustain and even grow the Jewish population both quantitatively and qualitatively. If more than 50% of interfaith families raise their children as Jews, interfaith families will actually increase the size of the Jewish population. But intermarried couples will only make Jewish choices if the Jewish community genuinely welcomes them. InterfaithFamily is a leading advocate for building such an inclusive Jewish community.

Historical U.S. Intermarriage Rates, 1970-2001

The following table is from the National Jewish Population Survey 2000-2001.[15]

 1 The National Jewish Population Survey 2000-2001: Strength, Challenge and Diversity in the American Jewish Population (New York: United Jewish Communities, 2004): 16. This 10-year-old data point is the most up-to-date figure on the national Jewish population. The UJC did not conduct another National Jewish Population Survey in 2010, and has no plans to conduct another nationwide survey.

 2 U.S. Religious Landscape Survey (Washington: The Pew Forum on Religion & Public Life, 2008): 34.

 3 NJPS 2000-2001, 17. Although based on entirely different samples, both the NJPS and Pew’s U.S. Religious Landscape Survey produced the same 31 percent figure.

Berman Institute North American Jewish Data Bank, Center for Judaic Studies and Contemporary Jewish Life, 2010): 3-8. The tables include data for many other cities as well.

 15 The percentage figure in the table represents the percentage of the marriages that took place, during the years indicated, that were intermarriages. In other words, for all marriages involving a Jew between 1980 and 1984, 38% were intermarriages.
