Cumulative Unionization and Physical Health Disparities among Older Adults

Whereas previous research shows that union membership is associated with improved health, static measurements have been used to test dynamic theories linking the two. We construct a novel measure of cumulative unionization, tracking individuals across their entire careers, to examine health consequences in older adulthood. We use data from the Panel Study of Income Dynamics (1970-2019) and predict self-rated health, functional limitations, and chronic health conditions in ages 60 to 79 using cumulative unionization measured during respondents' careers. Results from growth models show that unionized careers are associated with .25 SD to .30 SD improvements in health among older adults across all measures. Analyses of life course mechanisms reveal heterogeneous effects across unionization timing, age in older adulthood, and birth cohort. Moreover, subgroup analyses reveal unionization to partially, but not fully, ameliorate disparities based on privileged social positions. Our findings reveal a substantial and novel mechanism driving older adulthood health disparities.

Automated summary

Previous research has shown a positive association between union membership and improved health, but static measurements have been used to examine the dynamic relationship between the two. In this study, we develop a novel measure of cumulative unionization and track individuals across their entire careers to investigate the health consequences in older adulthood. The findings suggest that unionized careers are associated with significant improvements in health among older adults.
