Suddenly, as you may have noticed, millennials are everywhere. Not that this group of people born after 1980 and before 2000 — a giant cohort now estimated to number at least 80 million Americans, more than the baby boom generation — was ever invisible. What’s changed is their status. Coddled and helicoptered, catered to by 24-hour TV cable networks, fussed over by marketers and college recruiters, dissected by psychologists, demographers and trend-spotters, the millennial generation has come fully into its own. The word “millennial,” whether as noun or adjective, has monopolized the nonstop cultural conversation, invariably freighted with zeitgeisty import.

This newspaper is no exception. A recent search of The New York Times database turned up no fewer than 122 mentions of “millennial” so far in 2014, on topics ranging from TV and pop music to travel and literature.
