Why has the share of teens describing themselves as very happy fallen?
Core argument: The share of U.S. high school seniors describing themselves as "very happy" peaked at 24.8% in 2007 and was still 24.4% in 2012, before falling to 17.9% in 2019 and 11.4% in 2021, per Monitoring the Future.
Happiness has been measured in exactly the same way among high school seniors (17- and 18-year-olds) since 1976 in Monitoring the Future. The happiness item (“Taking all things together, how would you say things are these days – would you say you’re very happy, pretty happy, or not too happy these days?”) thus gives us the longest-running view of any indicator of psychological well-being among adolescents. By 2007, 24.8% of high school seniors said they were “very happy,” the highest ever recorded (before or since). Happiness stayed fairly high even through the years of the Great Recession (2007-09) and was at 24.4% as recently as 2012. That, as it turned out, was the end of an era. As smartphones and social media became pervasive in the 2010s, teen happiness plummeted. Teen happiness fell precipitously during the COVID years – only 11.4% of high school seniors described themselves as “very happy” in 2021. Coming out of the pandemic in 2023, that increased to 12.7%. But that is still much, much lower than the 17.9% of high school seniors who said they were “very happy” in 2019.
