Growing U.S. income inequality and the aging of Black and Hispanic populations point to greater risks of financial insecurity for older populations in coming years. Research on retirement determinants for Blacks and Hispanics is limited. Using data from the Health and Retirement Study, we analyze retirement determinants for Blacks and Hispanics. We link this data to the Working Trajectories file and restricted SSA individual-level files to determine Social Security wealth by race and ethnic origin. Using sociodemographic, health, and economic covariates, we construct a conditional probit model that identifies the probability a given individual will retire from the workforce over time. We find that Hispanics, Blacks, and non-Hispanic whites respond similarly to Social Security, private pension incentives, and other institutional (e.g., health insurance) influences on retirement. In their retirement decisions, non-Hispanic Blacks are not responsive to some sociodemographic characteristics (male, couple, and number of household members), but they are responsive to physical and mental health problems. Hispanics are less responsive than non-Hispanic whites to most sociodemographic characteristics (male, education, and couple) and mental health problems in their retirement decisions. Our findings for non-Hispanic whites are consistent with previous literature. Our research can inform programs and policies to improve the quality of life for older adults, especially those isolated by cultural, economic, educational, or other barriers.
