A 40-year study of teens finds Generation Z is unlike any past generation - here's what they're all about

Today's teens are in no hurry to grow up, a new study finds.

Contrary to teenagers of past generations, Generation Z - broadly defined as people born between 1995 and the mid-2000s - aren't drinking alcohol, having sex, driving, or going out without their parents nearly as much.

According to psychologists Jean Twenge and Heejung Park, who analyzed 8.3 million responses across seven surveys of teens from 1976 to 2016, today's 18-year-olds act more like 15-year-olds from years past.

The findings largely back up Generation Z as less reckless and more socially isolated than generations prior. Here's what they're all about.
