at is the relation between formal educational attainment and adults' subjective well-being? What factors account for variation in the estimates of this relation? Does education contribute to adult subjective well-being by increasing income or occupational status? To address these questions, we performed a metaanalytic research synthesis. Dependent variables were zero-and first-order correlations between educational attainment and subjective well-being, and independent variables were sample, measure, and study quality characteristics. We found that education is significantly positively related to adult subjective well-being, accounting for 1 to 3% of the variance. The relation is stronger in samples of women than men and in older than younger adults, but no differences were found between whites and blacks. The strength of the relation has not changed significantly over a span of nearly five decades. When occupational status, but not income, was the control variable the education/subjective well-being relation was reduced. Overall, education is a small but positive Work on this paper was supported by funds from the College of Education and Provost's Office, Arizona State University.
