Understanding the Largest Federal Assistance Program
Social Security is the federal government’s largest single program. Created in 1935, the program now consists of two parts: Old-Age and Survivors Insurance pays benefits to retired workers and to their dependents and survivors.
Disability Insurance (DI) makes payments to disabled workers who are younger than the normal retirement age and to their dependents. In all, about 50 million people now receive Social Security benefits.
During the program’s first four decades, spending for Social Security benefits steadily increased relative to the size of the economy, reaching about 4 percent of gross domestic product in the mid-1970s. That spending was driven largely by repeated expansions of the program.
Since then, spending for Social Security benefits has mostly fluctuated between 4.1 percent and 4.5 percent of GDP. In fiscal year 2007, it accounted for 4.3 percent of GDP.
How Social Security Works
In general, workers are eligible for retirement benefits if they are age 62 or older and have paid sufficient Social Security taxes for at least 10 years. Workers whose employment has been limited because of a physical or mental disability can become eligible for DI benefits at an earlier age and often with a shorter employment history.Various rules for determining eligibility and benefit amounts apply to family members of retired, disabled, or deceased workers.
When retired or disabled workers first claim Social Security benefits, they receive payments based on their average earnings over their working lifetime; those payments are subsequently adjusted to reflect annual changes in the cost of living. The formula used to translate average earnings into benefits is progressive.
In other words, it replaces a larger share of preretirement earnings for people with lower average earnings than it does for people with higher earnings. Both the earnings history and the specific dollar amounts included in the formula are indexed to changes in average annual earnings for the labor force as a whole.
Because average national earnings generally grow faster than the rate of inflation, that indexation causes initial benefits for future recipients to grow in real (inflation-adjusted) terms.
For retirement benefits, a final adjustment is made on the basis of the age at which a recipient chooses to start claiming benefits: The longer a person waits (up to age 70), the higher the benefits will be. That final adjustment is intended to be “actuarially fair,” so that an individual’s total lifetime benefits will be approximately equally valuable regardless of when he or she begins collecting them.
For workers born before 1938, the age of eligibility for full retirement benefits—referred to as Social Security’s normal retirement age—is 65. Under current law, that age is gradually increasing and will be 67 for people born in 1960 or later.
Specifically, the normal retirement age rises by two months per birth year for people born from 1938 through 1943 and again by two months per year for people born from 1955 through 1960. The age at which workers may start receiving reduced benefits—age 62—remains the same.
The Social Security Administration estimates that workers who retire at age 65 in 2008 having had average earnings throughout their career will be eligible for an annual benefit of about $15,000. That amount will replace nearly 40 percent of their preretirement earnings.
In later decades, the replacement rate will be less for workers with average earnings who retire at age 65, mainly because of the scheduled increase in the normal retirement age. Nevertheless, because initial benefits are indexed to average wages, which grow over time, the real value of those benefits will continue to rise.
Although Social Security is often characterized as a retirement program, it also provides other benefits. Indeed, only about 63 percent of its beneficiaries receive their payments as retired workers. As of September 2007, 14 percent of beneficiaries were disabled workers, 13 percent were survivors of deceased workers, and the remaining 10 percent were spouses or children of retired or disabled workers.
