Social Security began as a Depression-era safety net and has shaped retirement, disability, and survivor benefits for nearly 90 years

Social Security started in 1935 as a response to the Great Depression, when elderly people had lost savings and had no reliable way to support themselves. President Franklin D. Roosevelt signed the Social Security Act into law on August 14, 1935. The program was designed to provide income to retired workers age 65 and older, and it expanded over the following decades to cover disability and survivor benefits. Understanding how Social Security came to be helps explain why it works the way it does today — and what changes have happened along the way.

The program has changed significantly since its start. The earliest beneficiaries received much smaller payments than today's retirees, and the program originally excluded farm workers and domestic workers, which meant it left out many Black Americans and other workers of color. Over time, Congress expanded coverage, raised benefit amounts, and added new categories of people who could receive payments. These changes reflect both the program's growth and shifts in how Americans work and live.

Key Takeaways

  • Social Security began in 1935 as a federal program to provide income to retired workers, and later added disability and survivor benefits.
  • The program is funded through payroll taxes (FICA) that workers and employers pay, and benefits are calculated based on your earnings history.
  • may be able to access rules, benefit amounts, and the retirement age have all changed multiple times since the program started.
  • Today's Social Security faces funding challenges because there are fewer workers paying in relative to the number of people collecting benefits.

The original program: who it covered and how it worked

When Social Security began, it covered only workers in commerce and industry — roughly 60 percent of the workforce. Farm workers, domestic workers, government employees, and self-employed people were excluded. This meant that many workers, particularly in the South and rural areas, received no coverage at all. The first monthly benefit check went to Ida May Fuller, a retired legal secretary from Vermont, on January 31, 1940. She received $22.54.

The original retirement age was 65, which was significantly higher than the average life expectancy at the time. Workers had to have earned at least $2,000 in covered wages to receive any benefit. Spouses and children of retired workers could also receive payments, but the amounts were much smaller than what retirees get today. The program was designed to be modest — a supplement to savings and family support, not a complete replacement for work income.

Funding came from a payroll tax split between workers and employers. In 1935, the tax rate was 1 percent on wages up to $3,000 per year. Both the tax rate and the wage cap have increased many times since then. The money collected went into a trust fund, and benefits were paid from that fund. This basic structure — payroll taxes funding benefits — remains the same today.

How the program expanded after World War II

After World War II, Congress made major changes to Social Security. In 1950, coverage was extended to farm workers, domestic workers, and most self-employed people. This expansion brought millions of additional workers into the system. The same year, benefit amounts were increased significantly — the first major raise since the program began. These changes reflected both political pressure and the reality that Social Security had become more central to retirement security than originally planned.

In 1956, Social Security added disability benefits for workers under 65 and their families. This was a major shift: the program was no longer just for retirees. A worker who became unable to work due to a serious medical condition could now receive benefits, along with their spouse and children. The program was renamed Old-Age, Survivors, and Disability Insurance (OASDI), though most people still call it Social Security.

In 1965, survivor benefits were clarified and expanded. If a worker died, their widow or widower, children, and dependent parents could receive payments. These changes meant that Social Security became a form of life insurance as well as retirement insurance. The program grew substantially during this period, and so did the payroll tax rate — it rose from 2 percent in 1950 to 4.8 percent by 1960.

The shift to automatic cost-of-living adjustments

For decades, Congress had to pass a new law each time benefits needed to increase to keep up with inflation. This meant that retirees sometimes went years without a raise while prices climbed. In 1972, Congress changed this by creating automatic cost-of-living adjustments (COLAs). Starting in 1975, benefits would increase automatically each year based on inflation, without requiring a new law each time.

The COLA system was meant to protect retirees from losing purchasing power. However, it also increased the program's costs significantly. The payroll tax rate had to rise again to cover the higher benefits. By 1983, the program faced a serious funding crisis — the trust fund was nearly depleted, and there was not enough money coming in to pay all the benefits going out. Congress passed a major reform that year, raising the payroll tax rate and gradually increasing the full retirement age from 65 to 67.

The 1983 reforms also made some benefits taxable for higher-income retirees and expanded coverage to federal employees who had not been included before. These changes were intended to keep the program solvent for decades. For about 30 years, they worked — the trust fund built up a surplus. However, demographic changes have created new pressures on the system.

Why the retirement age changed and what it means now

The full retirement age — the age at which you can receive your complete benefit amount — was 65 for most of Social Security's history. In 1983, Congress began gradually raising it. For people born in 1943 or later, the full retirement age is now 67. For people born in 1960 or later, it is 67. The increase happened slowly over time to give workers time to adjust their retirement plans.

You can still claim benefits as early as age 62, but your monthly payment will be permanently reduced — by about 30 percent if you claim at 62 instead of 67. Conversely, if you wait until age 70 to claim, your benefit increases by about 8 percent per year. This means that the total amount you receive over your lifetime depends partly on how long you live and when you decide to start collecting.

The reason for raising the retirement age was life expectancy. When Social Security began, the average life expectancy was around 60 years. Today it is much higher. Congress reasoned that if people were living longer, the program needed to adjust when benefits began. However, life expectancy gains have not been equal across income levels — wealthier Americans have gained more years than lower-income Americans, which means the change affects different groups differently.

The funding challenge facing Social Security today

Social Security is facing a long-term funding problem. The program collects payroll taxes from current workers and uses that money to pay current retirees. This is called a pay-as-you-go system. For decades, there were enough workers paying in to cover the benefits going out, and the program built up a surplus in its trust funds.

However, two major demographic trends have changed the math. First, people are living longer, so they collect benefits for more years. Second, birth rates have fallen — there are fewer young workers entering the workforce relative to the number of retirees. In 1960, there were about 5 workers for every retiree. Today, there are about 3 workers for every retiree. By 2035, that ratio is projected to drop to about 2 workers for every retiree.

Because of these trends, the Social Security trust funds are projected to be depleted around 2034. After that point, the program would collect enough in payroll taxes to pay about 80 percent of scheduled benefits. Congress has not yet made changes to address this shortfall. Options include raising the payroll tax rate, raising the cap on wages subject to the tax, reducing benefits, raising the retirement age further, or some combination of these.

How your earnings history determines your benefit amount

Your Social Security benefit is calculated based on your earnings history — specifically, your 35 highest-earning years of work. The Social Security Administration (SSA) adjusts your past earnings for inflation and then calculates an average monthly income. Your benefit amount is based on this average, using a formula that replaces a higher percentage of income for lower-earning workers than for higher-earning workers.

This means that two people who earned the same total amount over their careers might receive different benefits if their earnings were spread differently across years. Someone who earned steadily for 40 years will have a higher benefit than someone who earned the same total but took time out of the workforce. If you have fewer than 35 years of earnings, zeros are counted for the missing years, which lowers your average and your benefit.

You can view your earnings record and estimated benefit amount by creating an account on ssa.gov. The SSA sends out statements showing your earnings history and projected benefits at different claiming ages. These statements are updated annually and can help you plan when to claim.

Changes that may affect future beneficiaries

Congress has proposed various changes to Social Security over the years, though none have been enacted into law since 1983. Some proposals would raise the payroll tax rate or eliminate the cap on wages subject to the tax (currently $168,600 for 2024, though this changes annually). Others would gradually raise the full retirement age beyond 67 or means-test benefits so that higher-income retirees receive less. Some proposals would combine multiple changes.

Any changes to Social Security would likely be phased in gradually to give workers time to adjust. Current retirees and people close to retirement would probably not be affected significantly. Younger workers might see different benefit amounts, different retirement ages, or different tax rates, depending on what Congress decides.

The program's history shows that Social Security has adapted to changing circumstances before. Whether and how it adapts to current funding challenges remains a matter of ongoing political debate.

Frequently Asked Questions

Why did Social Security originally exclude farm and domestic workers?

The program was designed to cover workers in commerce and industry, which were easier to track for payroll tax purposes. Farm and domestic work was often seasonal, informal, or paid in cash, making it harder to administer. These exclusions also reflected the racial and economic divisions of the 1930s South. Coverage was expanded in 1950 as administration improved and political pressure grew.

Can I see my complete earnings history?

Yes. Create an account at ssa.gov and log into your Social Security account. You can view your earnings record for every year you worked and see how much was credited to your account. The SSA also shows your estimated benefit amount at different claiming ages. Check your record every few years to make sure it is accurate, since errors can affect your benefit.

What happens to my benefits if I work after I start collecting?

If you claim before your full retirement age and earn above a certain amount, your benefits will be reduced. For 2024, the limit is $23,400 per year. For every $2 you earn above that, $1 is withheld from your benefits. Once you reach your full retirement age, there is no earnings limit. After that, you can work and collect your full benefit amount.

Will Social Security still exist when I retire?

Social Security will continue to exist, but the amount of benefits it can pay may change if Congress does not address the funding shortfall. Even if no changes are made, the program will still collect payroll taxes and be able to pay benefits — just not the full amount currently scheduled. Congress has time to make adjustments before the trust funds are depleted in 2034.
