September 22, 2021

Background
Recent news articles suggest a possible decrease in national
average wages due to the recent recession caused by the
Coronavirus Disease 2019 (COVID-19) pandemic. Such a
decrease would have a negative impact on the Social
Security benefits of individuals who reached age 60 in
2020. Social Security benefits are tied to a worker's
earnings record but are also affected by changes in national
wage levels, price levels, and claiming age.
Congressional interest in this issue may be high because of
the large number of potential beneficiaries for whom
benefits would be affected by a decrease in average wages
as measured by the Social Security Administration's
(SSA's) average wage index (AWI). Many other parameters
used by the SSA are adjusted automatically (typically on an
annual basis) based on changes in national average wages.
Projections for 2020
In July 2021, the Congressional Budget Office released its
updated baseline projections, which included several
projections for Social Security parameters. It estimates the
2020 AWI will be $54,036.00. This would represent a
decrease of about 0.0012% from the 2019 AWI of
$54,099.99. In August 2021, the Social Security Board of
Trustees released its 2020 Annual Report. Under its
intermediate assumptions-the best guess of future
experience-the 2020 AWI will be $55,576.94. This would
represent an increase of about 2.73%. In 2009, the only year
in which AWI decreased, the index declined by 1.51%.
Overview of AWl
Some Social Security parameters are adjusted annually
using the AWI. This adjustment ensures that the program
parameters reflect changes in the national wage levels.
The AWI is a dollar amount defined as the average of the
total wages for such particular calendar year and is subject
to regulations as prescribed by SSA's commissioner (42
U.S.C. §409(k)). Under current law, the commissioner is
required to compute the average of total wages based on
the amounts of wages reported by the Secretary of the
Treasury, including wages above the contribution and
benefit base (CBB). Wages above the CBB are not subject
to the Social Security payroll tax and are not included in
Social Security benefit computation. The AWI also includes
certain deferred compensations (20 C.F.R. §404.211(c)(3)).
H istory of AWl
Among other things, the Social Security Amendments of
1972 (P.L. 92-603) and the Social Security Amendments of
1977 (P.L. 95-216) amended federal law to provide a wage-
indexed benefit formula for initial benefits (i.e., benefits
payable at the earliest eligibility age, or 62) and to provide

for wage-indexed program parameters. All persons eligible
for benefits after 1978 would have their benefits calculated
under this new procedure. (AWIs for earlier years-1951
through 1977-were retroactively calculated.)
The 1972 and 1977 amendments and implementation of the
current wage reporting system in 1978 caused SSA to adopt
a different computation method for future years. Under the
new method, the amounts from an earlier year is a base to
which percentage changes from the new raw earnings data
are applied. Since this change was implemented, the AWI
value for a given year has usually been greater than the raw
earnings data. (In 2019 the average raw earnings were
$51,916.27 per worker, but the AWI was $54,099.99.)
Calculation of AW
Under current law, a given year's AWI is computed using a
three-step process. The first step uses the SSA raw earnings
data. A year's aggregate net compensation-compensation
plus contributions to deferred compensation plans less
certain distributions that were included in reported
compensation subject to income taxes-is divided by the
number of workers for that year. In the second step, the raw
earnings data for a given year is compared to the value from
the prior year to determine the year-over-year percentage
change in raw earnings data. In the third step, a given year's
AWI is determined by applying the percentage change in
the raw earnings data to the prior year's AWI dollar value.
For example, in 2019 the aggregate net compensation
($8,790,916,517,299.29) was divided by the number of
workers (169,328,746) to produce the per capita value of
raw earnings data of $51,916.27. The 2019 raw earnings
data was then divided by the 2018 raw earnings data
($50,040.96) to determine the percentage change in raw
earnings: 3.75%. Lastly, this percentage change was applied
to the 2018 AWI value of $52,145.80, which yielded the
2019 AWI value of $54,099.99.
SSA annually publishes this calculation in the Federal
Register. Typically, it takes about three quarters for SSA to
collect the wage data and perform the necessary AWI
calculations. The AWI calculations for 2019 were published
in the Federal Register on October 22, 2020 (85 Federal
Register 67413).
Typically, overall economy-wide earnings increase over
time. This results in a generally increasing AWI. In its 69-
year history, the AWI has increased in all but one year
(2009) and exhibited an average annual growth rate of
4.5%. For newly eligible workers, this leads to year-over-
year increases in initial benefits and stable replacement
rates (i.e., the portion of earnings that initial benefits
replace). Program parameters that are indexed to AWI
