We examine respondents in the Health and Retirement Study (HRS) to observe how their financial situations unfolded as they aged. We focus on low-income older adults and follow them over time to identify the factors associated with having low income at baseline and thereafter. We find that (a) real income remained relatively stable as individuals approached and entered retirement, and progressed through their retirement years, and (b) labor force participation declined and thus earnings became less important with age, while Social Security and retirement savings rose as a proportion of annual income.
