Urban Institute projections suggest the stock market collapse will have small effects on most Americans' retirement incomes. It's estimated that 37 percent of Americans born between 1941 and 1965 owned no stocks when the market crashed in 2008 and that income from assets will account for a small share of retirement income, even for those with stocks. For most retirees, Social Security provides the majority of income. Had Social Security been invested in private accounts with equities, the impact of the crash would have been much larger—positive or negative, depending on one's birth cohort and on future market performance.

Low-wage workers find it difficult to save for retirement. Without savings, they will have to rely on Social Security and pensions. Yet these income sources are based on earnings, which means that low-wage workers will have lower Social Security and pension benefits than higher-wage workers. This brief assesses whether boomers with low earnings between ages 22 and 62 are destined for low income at age 67. We find that nearly two-thirds of this group will end up with low income at retirement, but more than one-third will manage to defy the odds and escape being among the lowest-income older Americans.

This study uses the Urban Institute's DYNASIM model to project wealth and income at retirement for low-income boomers. The findings suggest that most with low lifetime earnings will also have low incomes at older ages unless they either continue working or move in with others who help support them financially. Saving more, working more consistently over their lifetime, and delaying retirement is projected to improve outcomes for low-earning boomers, but none of these actions will increase retirement living standards dramatically.

People think of retirement security as balancing on a three-legged stool, with income from assets, private pensions, and Social Security as the legs. However, despite growing awareness about the importance of saving for retirement, many elderly people cannot rely on their financial assets. According to data from the 2004 Health and Retirement Study, lower-income adults age 65 and older rely less on income from assets and traditional defined-benefit pensions than their higher-income counterparts. Instead, older adults with lower income rely primarily on Social Security and public transfers for their retirement security.

Income tax provisions affect the buildup of retirement assets during workers' careers and after-tax income following retirement. This paper uses the Urban Institute's DYNASIM model to simulate how potential changes in the tax treatment of retirement saving, Social Security benefits, and income from assets outside retirement accounts may affect boomers' retirement incomes. Changes in the income thresholds for taxing Social Security benefits have the largest impact on middle-income boomers, while changes in contribution limits for retirement saving plans and tax rates on capital gains and dividends have the largest impact on the highest-income boomers.

This report describes the work the Urban Institute performed to generate the Model of Income in the Near Term, Version 5 (MINT5). MINT is a tool developed for The Division of Policy Evaluation (DPE) of the Social Security Administration (SSA) to analyze the distributional consequences of Social Security reform proposals. MINT is a micro-level data file of individuals born between 1926 and 2018. It starts with a rich set of income and demographic characteristics from the 1990 to 1996 Survey of Income and Program Particpation (SIPP) data linked to SSA data on earnings and benefits. MINT then projects these characteristics until death or the year 2099.

This brief provides new evidence on the adequacy of boomers' retirement resources using the Urban Institute's DYNASIM model. Our findings show that boomers will accumulate more wealth and receive more income at retirement than previous generations. Nevertheless, boomers may need to increase their savings now or work longer to maintain their real living standards at retirement. [View the corresponding press release]

This analysis assesses the role of Social Security and Supplementary Security Income (SSI) in the economic well-being of baby-boomer retirees and their predecessors. The results suggest that, similar to current retirees, Social Security will account for about two-fifths of projected income for baby-boomer retirees. On average, SSI will contribute almost nothing to total income and will be received by fewer baby-boomer retirees than current retirees. Although baby boomers can expect higher incomes and lower poverty rates at retirement than current retirees have, they can also expect lower replacement rates. The decline in replacement rates is driven, in part, by a decline in Social Security replacement rates.

Encouraging work at older ages is a critical policy goal for an aging society, but many features of the current system of benefits and taxes provide strong work disincentives. The implicit tax rate on work increases rapidly at older ages, approaching 50 percent for some workers by age 70. In addition, by age 65 people can typically receive nearly as much in retirement as they can by working. If older Americans could overcome these barriers and delay retirement, they could substantially improve their economic well-being at older ages. For example, many people could increase their annual consumption at older ages by more than 25 percent by simply retiring at age 67 instead of age 62.

This paper provides new evidence on the adequacy of boomers' retirement resources using the Urban Institute's DYNASIM model. Our findings, which show that boomers will be wealthier at retirement than previous generations, are more optimistic than those of some other studies that have assessed the adequacy of retirement savings. A key difference between DYNASIM projections and other estimates is that DYNASIM projects a broader measure of income that includes Social Security and private pension benefits, as well as earnings and income from assets. Even with this more comprehensive income measure, our results suggest that boomers need to increase their savings or work longer to maintain their real living standards.
