This case study examines the demographic forces driving the global rise in aging populations, focusing on the implications for Social Security and public pension systems. It outlines how declining fertility rates, longer life expectancy, and policies such as China's one-child rule have widened the gap between working-age contributors and retirement-age beneficiaries. The paper then reviews Congressional Budget Office projections for Social Security spending, identifies federal health care costs as a compounding pressure, and evaluates three broad policy remedies. Finally, it considers how small and medium enterprises in housing, transportation, and education could benefit from an aging workforce that continues working past traditional retirement age.
The population of individuals aged 65 and older is larger than ever before, both in individual nations and across the world. When this growth is combined with a falling population of working-age individuals, the result is that more people are reaching the age at which they become eligible to draw upon Social Security pensions than there are workers paying into the system. To further complicate matters, people are living longer than ever before due to advances in science and medicine. The Social Security and Population Aging in the Developed World Project has reported that the "most important demographic development is an unprecedented rise in the proportions of elderly as a result of low fertility and high and still-increasing life expectancy" (Bongaarts, 2005, p. 1).
In countries such as China, where couples were historically limited to one child per family, the problem is exacerbated greatly. In other countries, such as the United States, modern methods of birth control and the intentional limiting of family size have heightened the imbalance between working-age individuals and those reaching retirement age.
Between 1961 and 2001, the proportion of the population under age sixteen fell by more than three percentage points, while the proportion of those aged 65 to 79 grew by more than two percentage points. The implications of these shifts are significant. Fewer individuals are working and paying into the Social Security system while more individuals are reaching retirement age and beginning to draw upon it. This situation threatens the long-term solvency of the Social Security retirement system — and, more broadly, the fiscal health of the United States federal government and its broader economy.
According to Congressional Budget Office Director Dan L. Crippen's testimony before the Senate Special Committee on Aging, once the baby-boom generation retires, "the portion of the nation's output that the federal government will spend on Social Security will increase by more than 50 percent — from 4.2 percent of gross domestic product (GDP) in fiscal year 2001 to an estimated 6.5 percent in 2030" (Congressional Budget Office Testimony, 2001). A primary source of this pressure is identified as "the rapidly escalating costs of the government's health care programs" (Congressional Budget Office Testimony, 2001).
The testimony further notes that while policymakers hold many goals, "if they want to limit the growth of spending on the elderly as a share of GDP, they have only two options: slow the growth of total payments to the elderly or increase the growth of the economy" (Congressional Budget Office Testimony, 2001). Complicating the situation is the fact that Social Security is not solely a retirement program: approximately two-thirds of Social Security beneficiaries are retired workers, with the remainder comprising disabled workers, survivors of deceased workers, and workers' spouses and minor children (Congressional Budget Office Testimony, 2001).
