Social Security: Brief Facts and Statistics
This document provides facts and statistics about Social Security that are
frequently requested by Members of Congress and their staffs. Its purpose is to
provide quick answers to basic questions about the program. It should not be treated
as a guide to Social Security. The reader is advised to consult other sources for
explanations of how eligibility and benefits are determined and how the program is
financed. Among them are the Social Security Administration’s (SSA’s) website at
[http://www.ssa.gov] and the Congressional Research Service’s (CRS’s) product line
of reports, issue briefs, and fact sheets on Social Security, accessible through the
CRS homepage at [http://www.crs.gov] (for congressional office users only). SSA
also issues numerous pamphlets on various aspects of the program as well as a
lengthy Handbook on Social Security. For other sources that provide data and basic
descriptive material, see the references listed at the end of this document.
This document is updated periodically.

Recipient Statistics
The federal Old-Age, Survivors, and Disability Insurance (OASDI) programs
collectively make up the system commonly referred to as Social Security. Officially,
there are two separate programs, each of which is administered by the Social Security
Administration (SSA) and managed by the operations of its own trust fund. The Old-
Age and Survivors Insurance (OASI) program and the Disability Insurance (DI)
program each disburse benefits to eligible retired or disabled workers and their
dependents, who have been covered by payroll contributions.
Recipients By Trust Fund and Eligibility Status
Benefit payments are disbursed by the relevant trust fund. Retired workers and
their eligible dependent family members, as well as the dependent family members
of deceased workers, receive benefits from the Old-Age and Survivors Insurance trust
fund. Disabled workers and their eligible dependent family members receive benefits
from the Disability Insurance trust fund. Table 1 breaks down recipients by trust
fund, by entitlement, and by age.

Tax Facts
The Social Security trust funds are financed by payroll taxes on covered
earnings. Being “covered” by Social Security means that a worker is employed in a
job or is self-employed and contributes a portion of his or her earnings to Social
Security. Workers not covered by Social Security are either covered by a similar
eligible contributory system offered by their employers outside of Social Security, do
not have high enough earnings for mandatory participation, or have another special
exemption. The type of workers exempt from coverage are provided below.
Workers Exempt From the Tax
! State and local government workers participating in alternative
retirement systems (HI tax is mandatory for workers hired since
April 1, 1986).
! Election workers earning $1,200 or less a year (in 2004).
! Career federal employees hired before 1984 who did not choose
Social Security coverage (HI tax is mandatory for all federal
workers);
! College students working at their academic institutions.
! Ministers who choose not to be covered, and certain religious sects.
! Household workers earning less than $1,400 a year (in 2004), and
those under age 18 for whom household work is not their principal
occupation.
! Self-employed workers with annual net earnings below $400.
Social Security Taxpayers in 2003
Covered workers contribute to Social Security by paying payroll taxes on their
earnings. Wage and salaried workers often have their contributions deducted from
each paycheck they receive, while self-employed must report earnings regularly with
the Social Security Administration. Table 3 provides the number of covered workers
that contribute to the Social Security system, as of December 2003. The total number
of taxpayers is much lower than the sum of the two coverage groups because
approximately six million individuals overlap coverage and engage separately in both
wage and salaried work as well as in self-employed work.

Social Security Tax Rates
Covered wage and salaried workers contribute 7.65% of their earnings below
the taxable maximum earnings threshold (explained below) to the Social Security
system. Employers of covered workers contribute to the system an additional 7.65%
of the earnings of each employee. The payroll taxes levied on workers and their
employers are called FICA taxes, after the legislation that created them, the Federal
Insurance Contribution Act.
Self-employed workers contribute roughly 15.30% of their net earnings to the
system. The payroll tax levied on the self-employed are known as SECA taxes, for
the Self-Employed Contribution Act. FICA and SECA tax rates are displayed in
Table 4. On paper, it appears that the self-employed are subject to a tax rate that is
double that of a wage and salaried worker, essentially equaling both the employee
and employer FICA portions. However, the self-employed receive two breaks that
are not offered to wage and salaried workers and their employers.
The first break is that not all of a self-employed worker’s earnings are subject
to SECA taxes. Only 92.35% of net earnings are subject to SECA taxes (meaning
that 7.65% is exempt). The second break is that one-half of the tax payments made
in the form of SECA contributions are deductible for income tax purposes.

* = The self-employed now compute the tax using only 92.35% of net earnings, and one-half of the
tax so computed is deductible for income tax purposes.
How the Tax Rates Are Divided
Portions of both the FICA and SECA tax rates are dedicated to fund both Social
Security and the Medicare Hospital Insurance (HI) program, also known as Medicare
“Part A.” Of the 7.65% FICA tax rate paid by both employers and employees, 6.2
percentage points go to OASDI, and the remaining 1.45% of the tax is used to fund
HI. Similarly, of the 15.3% SECA rate, 12.4 percentage points is dedicated to
OASDI, while 2.9% goes to HI. Table 5 provides a detail of the break down.

How Much Earnings Are Taxable
Covered workers contribute the proper percentage of their earnings by either the
FICA or SECA tax. However, not all earnings are subject to FICA and SECA taxes.
There is a maximum taxable earnings threshold, which rises each year with overall
wage growth. Earnings above the cap are not subject to the OASDI portion of the
FICA and SECA taxes. The earnings above the cap, however, are subject to the HI-
dedicated portion of the FICA and SECA taxes. The wage cap is effective for both
the employer and employee OASDI-dedicated portions of the FICA tax. Recent
wage cap limits are shown in Table 6. The Social Security Administration’s Office
of Policy estimates that 94.6% of covered workers had earnings below the maximum
taxable threshold in 2002, the latest year for which data is available.

Annual OASDI and HI Tax Payments in 2004
Self-employed workers are subject to the payroll tax rate which amounts to the
sum of both the employer and employee shares of the FICA tax rate. However, the
self-employed benefit from two breaks that reduce their overall tax burden. First,
self-employed workers are only required to make 92.35% of their net earnings
subject to the SECA tax rate. Wage and salaried employees have the FICA tax rate
applied to all (100%) of their earnings.

---

CRS-8
Second, self-employed workers can deduct one-half of their SECA tax
payments from their income taxes. For example, if a hypothetical self-employed
person had $35,057 in net earnings, an amount equivalent to the average wage earner
in the economy, they would pay SECA taxes on $32,375 of those earnings (92.35%
of $30,000). When the 15.3% SECA tax rate is applied to $32,375, the result is a
SECA tax burden of $4,953. In computing the effect of the income tax deduction,
one-half of the $4,953 tax burden ($2,477) is used for calculation purposes.
Assuming that this hypothetical self-employed worker with $35,057 in net earnings
is in the 15% marginal income tax bracket, a $2,477 income tax deduction is going
to result in a tax savings of an additional $372 (15% of $2,477). The net real tax
burden in this example would be $4,582 — instead of $4,953 without the income tax
deduction and $5,364 (15.3% of $30,000) without the income tax deduction and the
exemption from net earnings.
These computations are included in Table 7 to illustrate the tax burdens of both
wage and salary and self-employed workers with various earnings histories.

Source: Estimates made by CRS from data in the 2004 trustees’ report. The average and maximum
earnings levels are linked to real average increases in wages. The minimum wage annual earnings
level is obtained by multiplying the federal minimum wage for most workers, $5.15 per hour, by 2080
hours worked (40 hours worked per week, for 52 calendar year weeks). A maximum earner is
someone who earns the maximum wage subject to OASDI taxes ($87,900 in 2004).
** Employee share only.
*** Figures are net of federal income tax adjustments. Workers earning the minimum or the average
wage are assumed to be in the 10% and 15% marginal tax brackets, respectively. Maximum-wage
earners are assumed to be in the 30% marginal tax bracket.
Historical Level of Taxes
The FICA and SECA tax rates have been increased several times since the
beginning of the Social Security program. SECA taxes were not levied until after
1950, when coverage began for the first categories of self-employed workers. The
evolution of FICA and SECA tax rates and tax payments are shown in Table 8 and
Table 9.

Social Security Taxpayers Per Recipient
Much of the expected long-term financial strain on the Social Security system’s
ability to disburse benefits to future benefits lies in demographics. In the early years
of the system, there were more than ten covered workers contributing with payroll
taxes for every one person drawing benefits. Presently, there is barely more than
three covered workers for every beneficiary, and the Social Security trustees project

Benefit Facts
Benefit Formula
The Social Security benefit computation formula is progressive, as it uses “bend
points” to return higher percentages of a lower-wage worker’s lifetime indexed
earnings, computed on a monthly basis. For 2004, the bend points used in the benefit
formula are $612 and $3,689, respectively, and are increased annually based on
average wage growth.
If all or most of a worker’s indexed earnings fall under the first or second bend
point, they will see a higher replacement rate of average monthly earnings as
compared to monthly Social Security benefits. The more earnings a worker may have
beyond the second bend point, the lower the net return that worker will see in
augmenting their Social Security benefit.
For basic benefit (or primary insurance amount):*
! 90% of first $612 of AIME,** plus
! 32% of AIME over $612 through $3,689, plus
! 15% of AIME over $3,689
For maximum family benefit:
! 150% of first $782 of basic benefit, plus
! 272% of basic benefit over $782 through $1,118, plus
! 134% of basic benefit over $1,129 through $1,472, plus
! 175% of basic benefit over $1,472
* Without adjustment for early or delayed retirement or other factors.
** AIME = average indexed monthly earnings
Quarters of Coverage (QCs) Required for Eligibility
To qualify for retired or disabled worker benefits, an individual must
accumulate the required number of quarters of coverage. A worker must have
covered earnings equal to or exceeding the prescribed amount ($900 in 2004) in a
calendar quarter to earn a quarter of coverage. While a minimum of 40 covered
quarters must be achieved to be “vested” in the system to receive retirement benefits
in most cases, disabled worker benefits may be granted with as few as six quarters
of coverage, if the onset of the disabling condition or event occurred while the
worker was at young enough age. The number of quarters of coverage needed under
different circumstances is illustrated in Table 11.

Minimum Ages To Receive Benefits
In addition to covered earnings and length of coverage employment, receipt of
many OASDI benefits is conditional with age. Table 12 shows the earliest eligibility
ages (EEA) and maximum eligibility age that qualify or disqualify a worker or
dependent for benefit payments. Retired worker, spousal, and widow(er) benefits all
have a “full” or “normal” eligibility age (FRA or NRA), in which benefits are not
penalized for early receipt. In cases where an eligible claimant files for benefits
between the earliest eligibility age and the normal retirement age, the amount of the
monthly benefit is subject to an actuarial reduction, with the reduction being lower
the closer the claimant is to reaching the normal eligibility age.

CRS-13
Ages At Which Persons Receive Full Retirement Benefits
For purposes of qualifying for spousal or widow(er)’s benefits, the full or
normal retirement age (known as both the FRA or NRA), has little to do with
retirement, as claims to these benefits is not conditional on a covered work history,
or more specifically, the ceasing of work. In fact, the FRA is misleading to workers,
too, because leaving the workforce is not a condition for retirement benefit eligibility.
Rather, the FRA is simply a qualifying age threshold.
For many years, the Social Security full or normal retirement age remained
constant at 65 years. In 1983, however, a comprehensive Social Security reform
package that included many programmatic changes altered the law to gradually phase
in an increase of the normal retirement age. Starting with those born in 1938, the full
retirement age will be higher than age 65, depending on your year of birth. The
highest the full retirement age is scheduled to hit is age 67, affecting those born in
1960 and later. Table 13 provides the full schedule of current law increases
scheduled to take effect.

Average Monthly Benefits
OASDI benefits are paid to retired and disabled workers, as well as to their
eligible dependent family members. The benefit formula illustrated above is used to
compute primary insurance amounts (PIAs) for eligible retired or disabled workers,
but benefit amounts paid to dependents are determined by applying the relevant
percentage amount of the worker they are dependent upon. Typically, eligible
spouses and children of workers can receive a monthly amount up to 50% of the
worker’s primary insurance amount. Surviving spouses may be eligible for a
monthly amount up to 100% of the worker’s PIA. Factors that may reduce these

maximum percentage amounts include early eligibility, a dependent’s own work
record and subsequent benefit eligibility based on that work record, remarriage, and
other factors. Table 14 provides average monthly benefit amounts for selected
beneficiary categories before and after the application of the 2005 annual cost-of-
living (COLA) automatic benefit increase (more on COLAs below).

Social Security Benefit Increases
Social Security benefits are inflation-protected by the application of an
automatic annual cost-of-living adjustment (COLA). The percentage applied to all
beneficiaries is compiled from economic indicators that track inflation of prices on
goods and services over the previous year. The COLA is applied so beneficiaries do
not lose their purchasing power over time as they would if benefits were held
constant while prices of goods and services generally increased.
Prior to 1975, COLAs were applied sporadically to increase benefit levels to
keep pace with inflation. Starting in 1975, COLAs have been applied annually, with
the exception being when their effective date was switched from July to January, and
there was no COLA applied in the months between July 1982 and January 1984.
Table 15 and Figure 2 illustrate the full history of benefit level increases, while
Figure 3, for a different perspective, focuses on recent COLAs.

Initial Monthly Benefits for Workers Retiring in 2004
Table 16 shows what workers with different earnings histories would receive
in monthly benefits when retiring in 2004. The disparity in benefit amounts in the
two columns is affected by the fact that a worker born in 1939 and turning 65 during
the 2004 must wait until four months past his/her month of birth before receiving
unreduced benefits at the full retirement age. See Table 13 for the schedule of full
retirement ages.

different earnings histories and benefit election at age 65, are shown in Table 17.

Benefit Reductions and Offsets
While election for retirement benefits is not conditional on leaving the work
force, earnings from work can reduce monthly benefits that are received before the
full retirement age. In years preceeding the year in which one will reach the full
retirement age, benefits are reduced $1 for every $2 of earnings over the base
earnings test annual exemption amount ($11,640 in 2004). In the calendar year in
which one will reach the full retirement age, benefits are reduced $1 for every $3 of
earnings over a much higher second earnings test exemption amount ($31,080 in
2004). After reaching the full retirement age, beneficiaries are not subject to any
benefit reductions due to earnings. Table 18 provides the thresholds for the earnings
test, as well as other basic benefit reductions or offsets.

Maximum Monthly Earnings From Work Permitted for
Disability Benefits
The primary indicator in determining one’s eligibility to receive Social Security
disability benefits is one’s ability to partake in gainful employment. There are two
earnings thresholds that are applied to determine if a disability beneficiary or
claimant is gainfully employed or has the ability to be gainfully employed - they are
known as the monthly “substantial gainful activity” (SGA) levels.
In 2004, those beneficiaries who disabling condition is blindness, the level of
SGA before loss of eligibility is $1,350 per month. For all other disabled
beneficiaries, the monthly SGA amount is $810. These amounts are provided in
Table 19.

How Long It Takes To Get Your Taxes Back
Similar to the fact that lower-wage workers receive a higher replacement rate
of benefits to earnings that higher paid workers, it also takes less time for lower-wage
workers to recoup the value of worker payroll tax contributions in monthly benefit
payments. Table 20 provides expected payback times of workers with varying wage
histories.
Since spouses with no earnings histories are eligible for monthly benefits when
they meet certain factors such as age requirements, worker and spouse receiving
benefits simultaneously significantly reduces the expected time of recoupment of the
workers contributions.

* Time it takes to recover retirement portion of the Social Security payroll tax with interest. Assumes
worker retired in January 2003 at age 65 after having worked steadily since age 21 (age 22 for
maximum-wage earner). A low-wage earner is someone who always earned approximately 45% of
the national average wage. A maximum-wage earner is someone who always earned the maximum
amount subject to the Social Security tax. Assumes the worker’s spouse is also age 65. The
“retirement portion” of the tax is approximate since the law does not actually isolate the “old age”
portion. Medicare benefits and taxes are excluded from the figures. Interest assumed to be equal to
rates that accrue on government securities with four-year or longer maturities. (All figures based on
intermediate assumptions of the 2003 trustees’ report.)

Security benefits and other income can subject different proportions of the Social
Security benefits to income taxes.

Economic Facts
Income of Social Security Recipients
Many Social Security beneficiaries rely on benefit payments to make up a
significant portion of their income. The incomes of many lower income beneficiary
families is largely dependent on Social Security payments, and for 40% of single
beneficiaries over age 65, Social Security payments make up 90% or more of the
individual’s income.
Table 23 shows distributions of beneficiaries and aggregate Social Security
benefit payments by income band. The lowest income band listed contains the
highest number of beneficiary families, yet receives only the third highest proportion
of benefit payments.

Social Security’s and Medicare’s Costs as Percent of Federal
Budget, FY2004
Social Security and Medicare make up a significant portion of federal spending.
Table 25 shows that the two programs combined make up over one-fourth of federal
outlays.

Social Security and Medicare Spending as Percent of
Gross Domestic Product (GDP)
As a proportion of the overall economy is as measured by gross domestic
product (GDP), Social Security and Medicare combined spending will increase by
54% from 2004 to 2030. As Table 26 shows, in 2004 Social Security and Medicare
spending make up 5.83% of GDP. In 2030, it is projected that the two programs will
account for 8.95% of GDP.

Financial Status of Social Security Trust Funds
The Social Security trust funds currently bring in much more revenue than what
is needed for benefit obligations and have accumulated large balances. However, in
the near future payroll tax revenue will no longer be sufficient for expected spending,
and the trust funds are projected to be no longer solvent by 2042. Table 27 and
Figure 6 illustrate the magnitude of the projected revenue shortfall and how quickly
trust fund balances will erode.
