Definition

Socioeconomic differentials in health are theorized to diverge, converge, or persist over the life course. To understand the mechanisms underlying these patterns, researchers have proposed three different theories: cumulative advantage/disadvantage theory (divergence), age-as-leveler theory (convergence), and persistent inequality theory (persistence). The cumulative advantage theory argues that SES differences increase with age, creating a wider socioeconomic status (SES) gap in health among older adults compared to younger adults (Ross and Wu 1996; see “Theory of Cumulative Disadvantage/Advantage”). On the contrary, the age-as-leveler theory posits that SES differentials are small in early adulthood, large in middle age, and...
