It's simple arithmetic, really. Thanks to increasing life expectancy and falling fertility rates, the share of older Americans is on the rise - and the number of working-age people is declining. As a result, the United States and many other countries are experiencing large increases in the old-age dependency ratio.
Americans 65 and older are disproportionately supported by social insurance programs like Social Security (Old Age, Survivors, and Disability Insurance, or OASDI), Medicare, Medicaid, and Supplementary Security Income (SSI). In the coming years, this oldest segment of the population is going to grow dramatically, as the working-age segment of the country, the people who mostly fund these programs through payroll and income taxes, will dwindle by comparison.
That's problematic, as it upsets the "support ratio," or, put another way, the old-age dependency ratio. The balance of the working-age population and the elderly - the old-age dependency ratio - is a key gauge of a country's ability to sustain old-age social insurance programs, points out Karen Kopecky, an Atlanta Fed research economist and associate policy adviser, who has studied the fiscal and economic effects of aging in the United States.
In 2010, there were 4.8 workers for each retiree. However, as the baby boomers - those born between about 1946 and 1964 - age, this number will decline to just 2.7 by 2040, according to U.S. Census Bureau projections. (See chart 1.)
The math is daunting. Eventually either social insurance benefits must decline or taxes must increase, or some combination of both, according to Toni Braun, Atlanta Fed Research economist and senior adviser.
"This increase in fiscal burdens is one of the key macroeconomic effects of an aging population," Massachusetts Institute of Technology economist James Poterba writes in a 2014 research paper.
Aging to be the biggest driver of federal spending
Government transfers, or benefits, to retirees are large and increase with age. The nonpartisan Congressional Budget Office (CBO) reports that in 2006, the most recent year data are available, the 15 percent of U.S. households headed by someone 65 or older received more than 60 percent of net federal transfers, or government payments minus taxes paid. (See the infographic and charts 2 and 3.)
What this will mean in 25 years is that the aging of the population will be the single largest factor affecting U.S. government spending on major health care programs and Social Security, according to the CBO. Expenditures for those two areas together already exceed all other noninterest spending, and that gap is likely to grow. In particular, expenditures on social insurance for retirees are predicted to more than double by 2040, according to CBO projections.
What is likely to happen varies by program.
Social Security and Medicare
The two biggest public programs that support the elderly are Social Security and Medicare. In 2014, Social Security outlays totaled about 5 percent of gross domestic product (GDP), and Medicare spending equaled about 3.5 percent of GDP. The Social Security Administration projects that Social Security expenditures will rise to 6 percent of GDP in 2034 and that Medicare costs will increase to 5.4 percent of GDP.
Increases in the old-age dependency ratio - more retirees per worker - significantly affect the sustainability of these programs because benefits to current retirees are largely financed by payroll taxes paid by current workers. If benefits are maintained at their current levels, the projected increases in the old-age dependency ratio will put a big dent in the paychecks of our children and grandchildren.
This is not a new issue. Congress has known of this problem for decades and created trust funds to ease the tax burden on future workers. However, Social Security Administration projections indicate that the funds are too small. Those projections show that the Medicare Trust Fund will be depleted in 2030 and the Social Security Trust Fund will be exhausted in 2034. Once the trust funds are gone, under current law, payments to retirees would have to fall suddenly and sharply. (See chart 4.)
Medicare in some ways presents a more urgent and complex challenge than does Social Security, Kopecky notes. Medicare outlays are projected to grow more rapidly than Social Security spending, mainly because health care costs are rising faster than inflation, although the rate of increase has slowed in recent years. But because the size of Medicare outlays is so closely tied to health care costs, the growth rate of Medicare spending is more uncertain than that of Social Security.
Medicaid, SSI, and other means-tested benefits for retirees
In means-tested social insurance programs, benefit eligibility depends on a person's financial situation - their current income and wealth, for example. Put simply, the more you already have, the less you get. Medicaid and SSI, the two largest means-tested social insurance programs for retirees, are small compared to Social Security and Medicare. Together, outlays from Medicaid and SSI accounted for about 1 percent of GDP in 2014. These programs are smaller because instead of paying benefits to all retirees, they target those with the greatest financial and medical need.
Although Medicaid expenditures on retirees are less than 1 percent of GDP, expenditures per enrollee age 65 and older are large and growing. They were about $15,000 in 2014 - versus about $4,000 for working-age adults - and are projected to exceed $23,000 by 2023, according to the Centers for Medicare and Medicaid Services (CMS).
Large costs for older enrollees are fueled by expenditures of the "oldest old" retirees - those age 85 and older - many of whom rely on Medicaid to finance long-term care costs including nursing home stays. As Kopecky notes, among public health care programs, Medicaid is the largest funder of long-term care for the elderly. In 2013, it financed 41 percent of all long-term care expenses, according to CMS, while Medicare covered just 18 percent.
SSI, the Supplementary Security Income program, is run and funded by the federal government. Medicaid is jointly operated and funded by the federal government and the states. These programs rely on revenue from income, payroll, sales, and property taxes, the bulk of which is collected from working-age individuals. (See the infographic.) As the old-age dependency ratio increases, total tax revenues from working-age individuals will decline relative to outlays to retirees from these programs.
How to fix the funding shortfalls today
To get a handle on how daunting the fiscal math is, consider what measures would be required to fix the budget imbalances immediately. To maintain Social Security benefits at their current levels over the next 75 years, the payroll tax would have to be immediately and permanently increased from its current level of 12.40 percent to 15.02 percent, the Social Security Administration estimates. In that scenario, a person earning $60,000 a year would pay about $1,500 more per year in taxes.
Alternatively, to keep taxes unchanged, benefits would have to be immediately slashed by 16.4 percent for all retirees. If that happened, a retiree receiving $20,000 a year in Social Security payments, roughly the average for someone who retired in 2014, would see a $3,280 cut in annual benefits. To maintain Medicare benefits at their current levels, the payroll tax rate would have to be immediately increased by 0.26 percentage points or, to keep taxes unchanged, benefits would have to be immediately reduced by 15 percent.
For fiscal policymakers, it would surely be very difficult to enact these drastic measures.
Unlike Social Security and Medicare, Medicaid and SSI are not funded by a dedicated revenue source and trust fund. Thus, the solvency of these programs is not an issue. Moreover, growth in Medicaid spending on long-term care has been somewhat mitigated by efforts to steer the elderly away from nursing home care in favor of less costly alternatives such as home care. Still, Medicaid and SSI combined constitute a significant portion of the federal budget, and Medicaid makes up a large portion of the states' budgets, Kopecky and Braun point out. In 2013, for example, these two programs accounted for 10 percent of federal spending and 19 percent of all state spending.
The costs of delaying reform
Digging out of this fiscal hole is a thorny political challenge. It is very difficult to legislate large increases in payroll or income taxes. And higher taxes have a depressing effect on the economy. Also, it is difficult to push through legislation that reduces benefits for retirees, who tend to be politically active. So there is a tendency for policymakers to delay taking either action. But the longer policymakers wait to address the fiscal challenges of aging, the more intractable the problems become, Braun observes, citing the case of Japan. (See the sidebar "Along with America, the World Is Graying.")
It's clear we need reform. So what do economists say about what potentially good reforms might look like?
An economic perspective on policy reforms
Social Security, Medicare, Medicaid, and SSI insure the elderly against various risks. Social Security furnishes a steady income to help insulate people from poverty very late in life. The size of one's Social Security benefits depends on one's earnings history. SSI provides additional transfers to elderly individuals whose Social Security benefits are especially low.
Of course, the elderly also face a high risk of large health care expenses. Medicare provides health insurance to all Americans 65 and older, but it does not cover long-term care expenses. That matters, as the prospect of long-term care is one of the two largest financial risks individuals face over their lifetime, second only to the risk of low lifetime earnings, according to a 2014 research paper by the Atlanta Fed's Kopecky and Tatyana Koreshkova of Concordia University.
Nursing home stays are particularly expensive. In 2010, it cost an average of $75,000 to spend a year in a semi-private room. Some seniors are fairly likely to face these costs. The average 50-year-old woman has a 38 percent chance of spending more than 100 days in a nursing home, and for the average 50-year-old male, the chance is 20 percent, Rand Corporation economist Michael Hurd and coauthors estimate in a 2014 research paper. Kopecky and Koreshkova report that 40 percent of those who enter a nursing home will stay for more than a year, 20 percent for more than three years, and 11 percent for more than five years.
Medicaid is the largest public insurer of long-term care. However, because only poorer individuals who meet a means test are covered by Medicaid, most of nursing home expenses are paid for out of pocket, from savings. Kopecky and Koreshkova calculate that savings for anticipated nursing home expenses account for 3.7 percent of private wealth in the U.S. economy, or more than $1 trillion. That's enough money to purchase the nation's entire stock of cars, pickup trucks, heavy cargo trucks, airplanes, ships, and every other form of transportation equipment.
Relatives are most common caregivers
Given how expensive long-term care can be, it is not surprising that family members provide much of this type of assistance. In fact, unpaid female family members are the most common care providers. As noted, females are also more likely to require long-term care.
Alzheimer's disease and other dementias are among the biggest reasons why people end up needing long-term care. Women and older minorities face heightened risks of dementia, numerous studies have found. In fact, women account for nearly two-thirds of Americans with Alzheimer's, according to the Alzheimer's Foundation. Taken together, these results suggest that minority females are most likely to require formal long-term care. (See the sidebar "Dementia Takes Large and Growing Economic Toll.")
Reforming social insurance for retirees
Though retirees face significant risks, it doesn't necessarily mean the government has a special role to insure against these risks, Kopecky and Braun point out. Americans, after all, have many years to prepare for retirement, and on average retirees have substantial savings. Private insurance markets sell a range of products that are specifically designed for retirees. Private annuities and reverse mortgages offer stable cash flows through the end of life, and private insurance markets also offer long-term care insurance.
Nevertheless, even if they plan well for retirement, some retirees will survive to an old age and find themselves sick, alone, and poor. This sad state may result from the death of a spouse or burdensome long-term care expenses due to dementia. And, again, this risk is particularly significant for females and minorities. What is special about the people who end up sick, alone, and poor is that they can't cope on their own by returning to work.
So in this sense, there is a special role for social insurance. In a formal analysis in 2016, Braun, Kopecky, and Koreshkova found that even though Medicaid, SSI, and other means-tested social insurance programs for retirees are relatively small, they provide valuable protections against these risks: households with both low and high lifetime earnings receive benefits, and means testing holds down the public costs of providing these benefits. Indeed, this research suggests that the current scale of these means-tested programs for retirees may be too small.
And even if the government were to fix the fiscal imbalances in the U.S. Social Security system now, its pay-as-you-go structure - current workers fund the benefits of current retirees - means that workers in future years will face larger payroll taxes to cover benefits of retirees.
Perhaps, then, it is time to consider an alternative way to provide public pensions, Braun and Kopecky suggest. One reform that has received considerable attention is a defined-contribution public pension, something like a 401(k) plan. Under this system, part of a worker's payroll taxes are used to fund a mandatory retirement savings account that belongs to an individual worker.
Defined-contribution public pensions have several advantages, the Atlanta Fed economists note. They work well when the old-age dependency ratio is high - the situation the United States is facing - because workers are saving for their own retirement. There is also less political uncertainty about the eventual size of benefits because the accounts are in workers' names, so there is not a shrinking pool of money that must be divvied up among all retirees. Contributions to these savings accounts also offer individuals a higher rate of return than their contributions to a pay-as-you-go social security system. Earlier research by economists including Atlanta Fed research director Dave Altig found that this type of social security reformenhances general social welfare.
The biggest hurdle would be in managing the transition from the current plan to a defined-contribution public pension system. In particular, how do you grandfather in current retirees? Economists have suggested strategies for dealing with this issue. One approach proposed by Juan Carlos Conesa of the Universitat Autonoma de Barcelona and Carlos Garriga, an economist at the Federal Reserve Bank of St. Louis, is to increase government debt to fund a couple of costly measures: to give those who are relatively close to retirement a deposit into their account for their previous contributions to Social Security, since they wouldn't be contributing to the savings account for an entire career, and to continue Social Security payments for existing retirees.
In this scenario, citizens at some future date would pay a minimal tax to cover interest on the newly issued government debt. The economists argue that this is good for future citizens because they have the benefit of their own personal retirement savings accounts and avoid high payroll taxes to support retirees in a society with a large old-age dependency ratio.
Other countries have done this. Sweden and a number of Latin American nations have implemented reforms along these lines. A lesson from Latin America: less affluent retirees still need a safety net, say Stephen Kay, a senior economist and director of the Atlanta Fed's Americas Center, and Tapen Sinha, an economist at Instituto Technologico de Mexico, who edited the 2008 book Lessons from Pension Reform in the Americas.
Means testing Social Security and Medicare
As an alternative to defined-contribution public pension plans, a somewhat less radical but perhaps more contentious solution would be to means test Social Security and Medicare benefits. Some countries, including Australia and the United Kingdom, have adopted means-tested public pension benefits. In those countries, the middle class and the needy continue to receive benefits. But benefits gradually fall with wealth, and the most affluent receive few or no benefits. In Australia, for instance, only about half of retirees receive public pensions.
In the United States, the sustainability of Social Security and Medicare is going to receive far more attention as the programs' trust funds dwindle. What specific reforms to make and how to implement them are difficult questions. Yet it is important to begin these discussions now and to take actions soon.
Japan's experience suggests that delaying public pension reforms casts a pall on the economy. The longer we wait, the larger are the tax increases or spending cuts needed to restore balance. And uncertainty about the nature of the eventual reforms makes it difficult for individuals to plan for retirement.
