Engaging young people in their 20s and 30s, the so-called millennial generation, is a high priority for Jewish philanthropists. Some funders have banded together to create new initiatives, including free trips to Israel, with the express purpose of drawing members of this generation into Jewish life. Others have gravitated to the so-called innovation sector, supporting millennials who dream up new programs to entice their peers into some form of Jewish participation. But for all the energy and money expended on such programs, one question remains unanswered: Will these efforts move people from shallow engagement to actively live a Jewish life or deepen their knowledge?
