Rabbi Evan Goodman runs Hillel, the campus Jewish center, at the University of California, Santa Barbara. In recent years, he's had to rethink his job.
"Years past, when I was in college," he says, the Jewish organization "was a rabbi at a campus that put up a schedule of classes ... and drew the same 10 students to everything all year."
These days, chances are good that half the Jewish students he works with have a parent who's not Jewish. One in three of them says Judaism isn't his or her religion.
