Demographic shifts drove the need for change
One of the most significant factors behind the decision to raise the retirement age was the changing demographic landscape of the United States. When the Social Security program was created in the 1930s, the average life expectancy was much lower than it is today. The original full retirement age of 65 was set when many people did not live long enough to collect benefits for very long, or at all.
Increased life expectancy
Advances in modern medicine, public health, and technology have led to a substantial increase in life expectancy over the past several decades. As people live longer, they collect Social Security benefits for a greater number of years during retirement. For example, in 1940, the life expectancy for a 65-year-old was about 12 years for men and 13.5 years for women. By 2019, those figures had grown to about 18 years for men and 20.5 years for women. This growing period in retirement created a financial strain on the Social Security system, which was not designed for such prolonged payouts.
Declining birth rates
The Social Security system is largely funded on a pay-as-you-go basis, where the payroll taxes from current workers pay for the benefits of current retirees. In the decades following the establishment of Social Security, higher birth rates meant a large number of workers supported a smaller pool of retirees. However, declining birth rates in later years shifted this dynamic. The ratio of workers to retirees has decreased, putting more pressure on the system. As a result, fewer workers are available to pay into the program for every beneficiary.
Ensuring long-term financial stability
The demographic trends of longer lives and fewer workers led to concerns about the long-term financial solvency of Social Security. By the early 1980s, the program faced an impending funding shortfall that required legislative action. The 1983 Social Security Amendments were a bipartisan effort to address this issue and stabilize the program for future generations.
The Social Security trust fund
The Social Security program is funded by the Old-Age and Survivors Insurance (OASI) and Disability Insurance (DI) Trust Funds. Payroll taxes paid by workers and employers are deposited into these funds. When the program takes in more revenue than it pays out, the surplus is invested in special U.S. Treasury bonds. However, in recent years, the program has been paying out more in benefits than it collects in taxes, requiring it to draw on these trust funds. The 2024 Trustees Report projected that the combined OASI and DI trust funds would be depleted by 2035, at which point tax revenues would only be able to cover about 83% of scheduled benefits. Raising the full retirement age was one of the measures taken to help address this long-term funding problem by reducing the total benefits paid out over time.
Comparing the effects of different solutions
Raising the retirement age was one of several strategies considered to restore financial stability. Other proposals, such as increasing the payroll tax rate or cutting benefits for all recipients, were also on the table. The gradual increase to age 67 was seen as a less drastic measure than immediate, across-the-board cuts.
| Solution Strategy | Advantages | Disadvantages |
|---|---|---|
| Increase Full Retirement Age | Preserves the existing benefit formula; offers a gradual, less disruptive change; reflects increased longevity. | Acts as a benefit cut for future retirees; disproportionately impacts lower-income workers with shorter life expectancies. |
| Increase Payroll Tax Rate | Could fully close the funding gap; distributes the cost across all current workers. | May burden workers and employers, particularly those with lower incomes; could be politically unpopular. |
| Reduce Benefits Across the Board | Restores solvency immediately and affects all retirees equally. | Directly reduces the income of retirees; disproportionately affects lower-income individuals who rely more on Social Security. |
| Raise Cap on Taxable Earnings | Increases revenue from higher-income earners; makes the system less regressive. | Opponents argue it could disproportionately tax high-income earners relative to their benefits. |
The path to 67 and beyond
The 1983 amendments did not implement the change to age 67 immediately. Instead, they established a gradual schedule to phase in the higher age. The full retirement age for Americans born between 1938 and 1959 was increased incrementally by a few months each birth year. For those born in 1960 and later, the full retirement age was set at 67. The final step of this transition was reached for those turning 67 in 2027.
As the population continues to age and life expectancies potentially increase further, discussions about future changes to the retirement age may arise again. Some proposals have suggested further raising the age to 70 or indexing it to life expectancy. While these suggestions are aimed at addressing future solvency issues, they remain a topic of ongoing political debate, considering the unequal impacts on different socioeconomic groups.
Conclusion: A response to shifting realities
The decision to raise the retirement age to 67 was a complex policy choice driven by inescapable demographic and financial realities. The aging of the population, a result of longer life expectancies and lower birth rates, threatened the long-term solvency of the Social Security program. The 1983 amendments, a bipartisan legislative package, phased in the higher age to help shore up the trust funds and ensure the program's continuation. While the change effectively reduces lifetime benefits for future retirees, it was viewed as a necessary adjustment to reflect modern longevity and maintain the system's financial health for millions of Americans. It serves as a reminder that long-term retirement planning requires a clear understanding of the evolving landscape of public policy and demographics.
