This study examines changes in well-being globally, regionally, and nationally (N = 207,919) using Global Flourishing Study data. Life satisfaction declined consistently worldwide with large effect sizes (e.g., Asia: d = –0.41; Nigeria: d = –0.77). Life worthwhileness showed moderate declines across most regions (Asia: d = –0.39; Middle East Africa: d = –0.23). Happiness declined moderately and relatively uniformly, especially in Asia (d = –0.37), the Middle East Africa (d = –0.35), and North America (d = –0.13), while Europe and Latin America showed mostly non-significant changes. Country-level effect sizes ranged from negligible to large, indicating heterogeneity. The widespread decline in happiness suggests emotional well-being is more sensitive to global stressors than life satisfaction or worthwhileness. These findings highlight global well-being under strain and the importance of large-scale longitudinal data.
