Meet America’s Jews: They’re older, more educated, richer and less religious, on average, than the rest of the country. They’re overwhelmingly white, though Jews under 30 are more diverse. Most of them care about Israel, though one in 10 support the movement to boycott it. Most of their young adults are marrying non-Jews, though the growing Orthodox community is not. Those are some of the many findings of a study on Jewish Americans published Tuesday by the Pew Research Center. It’s a follow-up of a landmark 2013 study that has shaped the American Jewish conversation ever since. The 2013 survey measured not only the size and makeup of American Jewry, but quantified what those Jews believed (or didn’t), how they practiced their religion (or didn’t), whom they married, how they raised their children and how they felt about Israel.
