Why 20 Somethings Are Choosing a Slower Path to Adulthood, and Why It’s Good for Everyone, Richard Settersten, Ph.D. and Barbara Ray. Drawing on a ten year study and over 500 interviews, the authors, both members of the MacArthur Foundation Network on the Transition to Adulthood, shatter common myths about why young people are delaying adulthood. By examining seismic changes in the structure of family and the economy, the authors argue that there is a great divide, between “explorers” and “drifters,” each of whom face different challenges, and in the case of the first group, opportunities.
