If today’s teens were a generation of grinds, we’d see that in the data. But eighth-, 10th, and 12th-graders in the 2010s actually spend less time on homework than Gen X teens did in the early 1990s. (High-school seniors headed for four-year colleges spend about the same amount of time on homework as their predecessors did.) The time that seniors spend on activities such as student clubs and sports and exercise has changed little in recent years. Combined with the decline in working for pay, this means iGen teens have more leisure time than Gen X teens did, not less.
So what are they doing with all that time? They are on their phone, in their room, alone and often distressed.
