JEFFREY JENSEN ARNETT, a psychology professor at Clark University in Worcester, Mass., is leading the movement to view the 20s as a distinct life stage, which he calls “emerging adulthood.” He says what is happening now is analogous to what happened a century ago, when social and economic changes helped create adolescence — a stage we take for granted but one that had to be recognized by psychologists, accepted by society and accommodated by institutions that served the young. Similar changes at the turn of the 21st century have laid the groundwork for another new stage, Arnett says, between the age of 18 and the late 20s. Among the cultural changes he points to that have led to “emerging adulthood” are the need for more education to survive in an information-based economy; fewer entry-level jobs even after all that schooling; young people feeling less rush to marry because of the general acceptance of premarital sex, cohabitation and birth control; and young women feeling less rush to have babies given their wide range of career options and their access to assisted reproductive technology if they delay pregnancy beyond their most fertile years.
