US Birthright Participants 160% More Likely to Marry Jews
By Susan R. Eisenstein
U.S. Jews who participated in Birthright trips to Israel are more highly identified and engaged in communal life than their peers who did not, according to an analysis of the Pew Research Center’s 2020 survey of American Jews conducted by researchers at the Cohen Center for Modern Jewish Studies at Brandeis University.
The profound disparity in attitudes and behavior also held true when the analysts took into account differences in the respondents’ backgrounds.
Among the adults surveyed by Pew, nearly 45% had been eligible to participate in the free 10-day Birthright Israel heritage trips. The Brandeis researchers, led by Professor Leonard Saxe, analyzed the raw data made available by the Pew Center. The findings are to appear in the academic journal Contemporary Jewry.
Saxe and colleagues performed an analysis that compared respondents of similar backgrounds—some of whom had participated in Birthright and others who had not been to Israel. The survey included questions about Jewish identity, religious observance, cultural involvement, connections and attitudes towards Israel, perceptions of antisemitism and political leanings.
Those who had participated in Birthright were:
- 85% more likely to be “somewhat/very” attached to Israel (63% compared to 34%);
- 54% more likely to feel a “great deal” of belonging to the Jewish people (40% compared to 26%);
- 58% more likely to feel “a lot” in common with Israeli Jews (71% compared to 45%);
- 160% more likely to have a spouse who is Jewish (39% compared with 15%);
- 45% more likely to have attended a Seder the previous Passover (77% compared to 53%); and
- 53% more likely to have donated to a Jewish charity (29% compared to 19%).
