Income and wealth disparities among older households were wider in the United States than in selected countries from 1998 through 2019, according to GAO's review of households headed by those 55 and older. For example, in 2007, the median, or “typical,” income of high-income older households in the United States was about 12 times greater than that of low-income households, compared to about 6 times in Germany and about 10 times in the United Kingdom (see figure). GAO's analysis also indicates that income and wealth were more concentrated at the top of high-income and high-wealth older households in the United States, compared to other households in either the United States or selected countries. Further, GAO's analysis shows that high-wealth older households in the United States and United Kingdom held a greater proportion of their wealth in financial assets, relative to middle-wealth households. Still, homes and other non-financial assets made up the majority of total wealth for all older households GAO reviewed. Although the wealth data GAO reviewed indicate wider disparities in the United States than in selected countries over the period of review, these data did not include the estimated value of retirement benefits that older households expect to receive from public and private sources. GAO and some researchers have demonstrated how incorporating the value of these expected retirement benefits shows wealth disparities that are somewhat smaller than measures that omit these benefits. GAO's analysis indicates that higher income and wealth are associated with living longer among older individuals in the United Kingdom and United States. To compare survival between the United Kingdom and United States, GAO used data from 2002 through 2012, which are the most recent years for which there are reliable mortality data for both countries. The data sets GAO used for this analysis are unique in that they are representative of older individuals in the United Kingdom and United States and follow the same individuals as they age, while tracking their mortality over time, as well as their income, wealth, and other demographic information. As a result, GAO examined survival rates over a 10-year period, as a proxy for longevity. GAO found that individuals from high-income and high-wealth households in the United States and United Kingdom were generally more likely to survive during the 10-year period compared to lower household income and wealth groups. For example, in the United States, the proportion of individuals in their seventies at the beginning of the study period who were alive at the end of the 10-year period ranged from 68 percent for those from the wealthiest households, to 44 percent for those from the least wealthy households. However, these patterns differed for the oldest individuals, who were in their eighties and nineties at the beginning of the study period. For example, survival rates for those in their nineties did not vary significantly based on wealth. Educational attainment and homeownership in selected countries and the United States are associated with higher levels of income and wealth according to GAO's examination of data, review of research, and interviews. For example, in each of the selected countries, older households that have obtained postsecondary education tend to have higher incomes during their working years and subsequently higher levels of wealth during their older years. Homeownership is similarly associated with higher levels of wealth because, in part, a house serves as an asset that can increase in value, as well as a dwelling. Other factors associated with income and wealth disparities include the cost of long-term care, which can quickly deplete the wealth of older households. However, research indicates that Germany mitigates the high costs of long-term care through nationwide long-term care insurance. Additionally, public retirement programs in selected countries and Social Security in the United States are designed in part to reduce disparities by providing a higher rate of payments to households with lower incomes. Similarly, income taxes in all three selected countries and the United States are designed in a way that can reduce income disparities, with marginal rates that increase by income.
