Social Security is one of the most important sources of retirement income in the United States. Millions of older Americans depend on monthly benefits to cover essential expenses, including housing, food, utilities, and healthcare. For some households, these payments provide most of the money available each month. For others, Social Security works alongside pensions, retirement accounts, investment income, and personal savings.
But how many retirees actually receive almost all their income from Social Security? The answer depends on how the data is collected and which income sources are included.
Some surveys suggest that a substantial share of retirees depend entirely on Social Security. However, research that connects survey responses with federal tax records provides a different estimate. According to Census Bureau research, approximately 14% of adults aged 65 and older living in families that receive Social Security obtained at least 90% of their family income from the program.
That is roughly one in seven older adults in the population examined. The difference between survey estimates and administrative records also raises an important question about retirement security: Are retirees reporting all the income they receive, including withdrawals from retirement accounts and other savings?
Findings
Social Security benefits provide a regular source of income for retired workers, eligible spouses, and certain surviving family members. For many households, these payments help replace some of the earnings lost when employment ends.
A 2025 survey from the Transamerica Center for Retirement Studies found that 91% of retirees received income from Social Security, while 53% identified it as their primary income source. These findings demonstrate the program’s broad role in retirement finances.
Another survey, conducted by The Senior Citizens League, reported that 39% of retirees said Social Security provided their entire income. However, survey responses do not always capture the full range of financial resources available to older households.
Census Bureau researchers have examined this issue by comparing survey information with administrative records from the Internal Revenue Service and the Social Security Administration. Their findings indicate that the share of older adults receiving at least 90% of their family income from Social Security is substantially lower than some survey results suggest.
The distinction matters because identifying Social Security as a primary income source is not the same as receiving nearly all household income from the program.
A retiree may depend on Social Security for regular expenses while also withdrawing money from a 401(k), receiving a pension, or earning interest on savings. When those additional sources are omitted from a survey response, the reported level of dependence can appear higher than the actual level.
Statistics
The Census Bureau’s research, which examined income from 2015 using linked administrative records, provides a more detailed picture of how Social Security contributes to family finances among adults aged 65 and older in households receiving benefits.
The results show that some older adults depend heavily on Social Security, but many receive a substantial share of their income from other sources.
| Share of Family Income From Social Security | Percentage of Older Adults |
|---|---|
| At least 90% | 14% |
| At least 75% | 21% |
| At least 50% | 42% |
| Less than 50% | 58% |
These figures refer to adults aged 65 and older in families receiving Social Security, rather than all retirees in the United States.
The results show that 42% received at least half their family income from Social Security, while 58% received less than half from the program. Only 14% crossed the 90% threshold.
The findings also illustrate why different definitions of retirement dependence can produce different results. Someone who receives 60% of household income from Social Security may rely on the program significantly, but that person does not meet the definition of receiving at least 90% of income from it.

Surveys
Survey data remains useful for knowing retirement finances, but the results depend on how questions are worded and how accurately respondents report their income.
For example, a retiree asked to identify their main income source may name Social Security because the benefit arrives regularly and pays for recurring bills. The same person may also take occasional withdrawals from an IRA or use investment income to cover other expenses.
If those withdrawals are not reported, the survey may show a larger share of income coming from Social Security than the household actually receives.
Research has identified reporting gaps involving retirement accounts. Earlier studies found that many older respondents who reported no retirement-account income had such income recorded in administrative data.
These differences can arise for several reasons. Respondents may forget occasional withdrawals, misunderstand the question, or report income differently depending on the period being considered. Retirement account distributions can also vary from year to year, making them harder to recall than a regular monthly benefit.
The Current Population Survey, which collects information about household income and employment, was redesigned in 2014 to improve retirement income measurement. However, challenges in capturing certain income sources continued.
The Census Bureau’s linked-data research helps address some of these limitations by comparing survey responses with federal records. Its findings provide an additional way to assess the financial resources available to older households.

Income
Social Security is only one component of retirement income for many Americans. Depending on their employment history, savings, and household circumstances, retirees may also receive pension payments, withdraw money from retirement accounts, or use investment income to meet expenses.
Transamerica’s retirement research identifies several additional sources of income among retirees.
| Retirement Income Source | Share of Retirees |
|---|---|
| 401(k), 403(b), or IRA income | 45% |
| Other savings and investments | 49% |
| Pension income | 40% |
| Home equity | 15% |
These percentages describe the share of retirees reporting each source. They are not mutually exclusive, meaning one person may receive income from several categories.
For example, a retired household might receive $2,000 per month from Social Security and withdraw another $1,000 from a retirement account. Combined, these sources provide $3,000 in monthly income, with Social Security accounting for approximately 67%.
In another household, a pension might cover a substantial portion of expenses, leaving Social Security to supplement the remaining budget. A household with investment income could have a similar pattern.
The availability of additional income does not necessarily mean that a retiree is financially comfortable. A household may have several income sources and still struggle with high housing costs, medical bills, debt, or inflation.
Likewise, owning a home does not automatically provide spendable income. Accessing home equity generally requires a financial arrangement, such as selling the property or using an eligible borrowing product, and each option has costs and risks.
The important distinction is between having Social Security as a source of income and relying on it for almost all household resources.
Demographics
Reliance on Social Security also varies by age and gender. Retirement income is shaped by lifetime earnings, marital status, access to workplace retirement plans, savings behavior, and the length of time a person has been retired.
A 2025 Congressional Research Service analysis found that reliance on Social Security roughly doubles between adults aged 65 to 69 and those aged 80 and older.
One possible explanation is that some older retirees gradually use their accumulated savings to cover living expenses. Healthcare costs and other expenses may also rise with age, while income from employment becomes less common.
Household changes can have an effect as well. A surviving spouse may lose part of the household’s previous income, depending on the benefits and other resources available. This can increase the share of the remaining household income represented by Social Security.
Women tend to rely more heavily on Social Security than men across age groups. Differences in lifetime earnings, time spent outside paid employment, caregiving responsibilities, and access to employer-sponsored retirement benefits can contribute to this pattern.
These differences do not mean that every older woman has fewer financial resources than every older man. Rather, they indicate that retirement income patterns vary across demographic groups and that averages cannot describe every household.
Benefits
Social Security benefits are calculated using a worker’s earnings history and other program rules. The age at which someone claims retirement benefits also affects the amount received each month.
For people born in 1960 or later, full retirement age is 67. Claiming benefits before full retirement age generally results in a lower monthly payment, while delaying retirement benefits beyond full retirement age can increase the payment until age 70.
However, delaying benefits is not necessarily the best choice for every person. Health, current income needs, employment status, household circumstances, and life expectancy can all influence the decision.
The Social Security Administration’s official retirement planner provides information about retirement planning and claiming benefits.
It is also important to distinguish between Social Security retirement benefits and the full range of government assistance that an older household might receive. Different programs have different eligibility requirements and serve different purposes.
Knowing which benefits a household qualifies for can help people estimate their retirement income more accurately.
Planning
The findings offer a practical lesson for people preparing to retire: Social Security should be included in retirement planning, but its role needs to be considered alongside other financial resources.
Workers who have access to employer-sponsored plans may benefit from understanding their contribution options, employer matching arrangements, and withdrawal rules. Those with individual retirement accounts should consider how their savings could support spending over several decades.
It is also useful to prepare a realistic retirement budget that includes housing, healthcare, food, transportation, taxes, and unexpected expenses. Comparing projected spending with expected Social Security benefits, pensions, and withdrawals can reveal whether additional savings may be necessary.
People already in retirement can benefit from reviewing their income sources periodically. Investment performance, changing expenses, medical needs, and household circumstances can all affect how much income is available.
At the same time, retirement planning should account for uncertainty. Savings may not grow as expected, inflation can reduce purchasing power, and people may live longer than they initially anticipate. Maintaining a financial cushion can help households manage these changes.
The Census Bureau’s estimate that about one in seven older adults in Social Security-receiving families receives at least 90% of family income from the program provides a useful benchmark. However, the figure is based on linked administrative data for 2015, not a direct count of retirees in 2026. More recent evidence suggests that reporting gaps remain relevant, but the historical estimate should not be treated as a precise current-year measurement.
Ultimately, Social Security remains a central source of financial support for older Americans, but the extent of dependence varies considerably. Some retirees receive nearly all their income from benefits, while others combine Social Security with pensions, retirement accounts, savings, and investments. Looking at the full range of income sources provides a clearer knowing of retirement finances and helps households make better-informed decisions about their financial future.
