What was done
The authors compiled 409 studies supporting a U-shaped trajectory of well-being across the lifespan and directly re-evaluated counter-claims from the psychology literature. They analyzed repeated cross-sectional survey datasets across multiple countries, including the Eurobarometer Surveys (1980–2019), the Gallup World Poll (2005–2019), the UK Annual Population Survey (2016–2019), and the US Census Bureau Household Pulse Survey (August 2021). Regressions evaluated the relationship between age and well-being with and without socioeconomic covariates, and re-analyzed data from studies claiming no U-shape.
What was found
The authors reported statistically significant, non-trivial U-shaped relationships between age and well-being across countries, persisting whether or not socioeconomic controls were included. Specific numerical effect sizes and confidence intervals were not reported in the abstract. The magnitude of the mid-life dip was described as comparable to major life events such as unemployment or spousal loss, and equal to roughly half of the total well-being decline observed in the UK during the 2020–2021 COVID-19 pandemic.
Why it matters
This study directly challenges assertions that the mid-life dip in subjective well-being is an analytical artifact or economically trivial, showing consistency across diverse international datasets.
Limits
The abstract does not report exact numerical sample sizes, point estimates, or confidence intervals. The primary datasets rely on cross-sectional or repeated cross-sectional survey data rather than long-term individual panel tracking across full lifespans.
