The World Happiness Report 2026 offers a troubling picture of youth wellbeing in the social media age. Its central finding is not that all young people everywhere are becoming less happy. In fact, in most world regions, the youngest age group is now as happy as, or happier than, older adults. The real drop appears in North America and Western Europe, where young people report much lower life satisfaction than they did 15 years ago. The report is careful not to blame a single cause, but it does argue that heavy social media use is an important part of the story, especially in English-speaking countries and Western Europe.

One reason this report is so persuasive is that it looks at many kinds of evidence. In the 2022 PISA survey, which covered more than 270,000 teenagers in 47 countries, 15-year-olds who used social media for more than seven hours a day had clearly lower wellbeing than those who used it for less than one hour. For girls in Western Europe, the gap was almost one full point on a 10-point life-satisfaction scale. The report also suggests that not all platforms are equally harmful: passive, highly visual, influencer-centered platforms seem to create stronger pressures for comparison. Even in the Middle East and North Africa, where youth happiness has not fallen overall, heavy users are still more likely to report stress and depressive symptoms. (worldhappiness.report)

Perhaps the most interesting message is that the problem is not simply “screens.” The report’s Europe-wide analysis found that internet use is strongly negative for Gen Z, moderately negative for Millennials, and close to neutral for older generations. It also links heavy online life to weaker trust, less social meeting, and a decline in the emotional foundations of wellbeing. That idea fits a broader trend from the previous World Happiness Report: in 2023, 19% of young adults worldwide said they had no one they could count on for support, up 39% from 2006. In other words, social media may hurt most when it replaces real connection instead of strengthening it. Policymakers are reacting too: Australia’s age restrictions for major platforms took effect on December 10, 2025, blocking account access for under-16s on ten services. (worldhappiness.report)
