Association Between Racial Wealth Inequities and Racial Disparities in Longevity Among US Adults and Role of Reparations Payments, 1992 to 2018

Abstract

ImportanceIn the US, Black individuals die younger than White individuals and have less household wealth, a legacy of slavery, ongoing discrimination, and discriminatory public policies. The role of wealth inequality in mediating racial health inequities is unclear.ObjectiveTo assess the contribution of wealth inequities to the longevity gap that exists between Black and White individuals in the US and to model the potential effects of reparations payments on this gap.Design, Setting, and ParticipantsThis cohort study analyzed the association between wealth and survival among participants in the Health and Retirement Study, a nationally representative panel study of community-dwelling noninstitutionalized US adults 50 years or older that assessed data collected from April 1992 to July 2019. Participants included 7339 non-Hispanic Black (hereinafter Black) and 26 162 non-Hispanic White (hereinafter White) respondents. Data were analyzed from January 1 to September 17, 2022.ExposuresHousehold wealth, the sum of all assets (including real estate, vehicles, and investments), minus the value of debts.Main Outcomes and MeasuresThe primary outcome was all-cause mortality by the end of survey follow-up in 2018. Using parametric survival models, the associations among household wealth, race, and survival were evaluated, adjusting for age, sex, number of household members, and marital status. Additional models controlled for educational level and income. The survival effects of eliminating the current mean wealth gap with reparations payments ($828 055 per household) were simulated.ResultsOf the 33 501 individuals in the sample, a weighted 50.1% were women, and weighted mean (SD) age at study entry was 59.3 (11.1) years. Black participants’ median life expectancy was 77.5 (95% CI, 77.0-78.2) years, 4 years shorter than the median life expectancy for White participants (81.5 [95% CI, 81.2-81.8] years). Adjusting for demographic variables, Black participants had a hazard ratio for death of 1.26 (95% CI, 1.18-1.34) compared with White participants. After adjusting for differences in wealth, survival did not differ significantly by race (hazard ratio, 1.00 [95% CI, 0.92-1.08]). In simulations, reparations to close the mean racial wealth gap were associated with reductions in the longevity gap by 65.0% to 102.5%.Conclusions and RelevanceThe findings of this cohort study suggest that differences in wealth are associated with the longevity gap that exists between Black and White individuals in the US. Reparations payments to eliminate the racial wealth gap might substantially narrow racial inequities in mortality.

Association of Cost-Driven Residential Moves With Health-Related Outcomes Among California Renters

“…Given the disparate prevalence of cost-driven moves by race, ethnicity, and other socioeconomic strata, which might result from differing economic opportunities and/or discrimination in housing, interventions to prevent cost-driven moves could help to interrupt a pathway by which structural racism produces health disparities. Combatting the upstream structural factors associated with economic inequality will be more challenging, but conversations around reparations offer a potential path forward …”

Complexity Epidemiology in Practice: A Tale of Two Simplicities

“…Subsequently, within that context, the dynamics of interaction between exposure(s) would be circumscribed in real ways, such as by time and cohort, obviating feedback loops that might be needed for studies at higher geographic or temporal scales. Recent efforts to compute the potential reductions in Black-White health inequities that would result from reparations payments 24 are an example of this potential, even in the absence of complexity models. Future analyses may refine the model through economic, psychological, and social theory; ethnography and qualitative research; and further empirical evidence, e.g., regarding effect modifiers such as timing, amount, and mode of distribution.…”

Principles to Guide the US Toward Better Health for All

“…It is also important to think about the assets that improve health more broadly than income alone. Wealth, or the total economic resources that persons accumulate over time, may be as important or more important than income . Other resources, such as stable housing, safe neighborhoods, and supports for child care and for healthy aging are essential.…”
