Abstract
PURPOSE OF REVIEW: This review summarizes findings from quantitative research studies published between 2010 and 2022 providing insight on sociodemographic differences and disparities in ageism among US adults ages 50 and older. FINDINGS: Across 21 studies, disparities in ageism were more consistently found such that those who were older (57% of studies), with less education (64%), and of lower socioeconomic status (100%) reported more ageism than their counterparts. Amount of ageism did not differ by sex in the majority (71%) of studies. Findings regarding race/ethnicity were mixed. Other possible differences in ageism, assessed in a small number of studies, were patterned by employment characteristics, geographic residence, religiosity, and political affiliation but not by marital or employment status. SUMMARY: Given that ageism is both common and associated with poor health outcomes, identifying disproportionately affected segments of the older adult population is a necessary prerequisite for developing targeted interventions to reduce negative outcomes linked to ageism and associated health disparities. Evidence within this review suggests that the patterning of ageism may deviate from that typically documented for other social and structural disadvantages. Some groups traditionally considered to be socially marginalized were found to report more ageism while others did not.
