More data for my analysis:
We're in the thick of what one sociologist calls "the changing timetable for adulthood." Sociologists traditionally define the "transition to adulthood" as marked by five milestones: completing school, leaving home, becoming financially independent, marrying and having a child. In 1960, 77 percent of women and 65 percent of men had, by the time they reached 30, passed all five milestones. Among 30-year-olds in 2000, according to data from the United States Census Bureau, fewer than half of the women and one-third of the men had done so. A Canadian study reported that a typical 30-year-old in 2001 had completed the same number of milestones as a 25-year-old in the early '70s.
The whole idea of milestones, of course, is something of an anachronism; it implies a lockstep march toward adulthood that is rare these days. Kids don’t shuffle along in unison on the road to maturity. They slouch toward adulthood at an uneven, highly individual pace. ...
Even if some traditional milestones are never reached, one thing is clear: Getting to what we would generally call adulthood is happening later than ever. But why? ... To some, what we're seeing is a transient epiphenomenon, the byproduct of cultural and economic forces. To others, the longer road to adulthood signifies something deep, durable and maybe better-suited to our neurological hard-wiring. What we’re seeing, they insist, is the dawning of a new life stage — a stage that all of us need to adjust to.
I'm trying to work up a theory about people born after 1980, which seems to be the cut-off for a host of behaviors and attitudes that are alien to me and my contemporaries. I'm not sure how on-point this article is, but I'm thinking about it.
