Stew Friedman, founding director of The Wharton School's Work/Life Integration Project, studied two generations of Wharton college students as they graduated: Gen Xers in 1992 and Millennials in 2012. The cross-generational study produced a stark discovery—the rate of graduates who plan to have children has dropped by nearly half over the past 20 years. At the same time, men and women are now more aligned in their attitudes about dual-career relationships, and they are opting out of parenthood in equal proportions. But their reasons for doing so are quite different. In his new book, , Friedman draws on this unique research to explain why so many young people are not planning to become parents. He reveals good news, that there is a greater freedom of choice now, and bad, that new constraints are limiting people's options. In light of these present realities, he offers ideas for what we can do as a society, in our organizations, and for ourselves to make it easier for men and women to choose the lives they want. In this book, Friedman addresses: + How views about work and family have changed in the past 20 years + Why men and women have different reasons for opting out of parenthood + How family has been redefined + Why we are all now part of a revolution in work and family + What choices we face in our social and educational policy + How organizations and individuals—especially men—can spur cultural change In the debates on work and family, people of all generations are calling for a reasoned, thoughtful, research-driven contribution to the discussion. In , Friedman offers just that: an astute assessment of how far we have come and where we need to go from here.
