US Pensions Spending History from 1900
In 1902 governments in the United States spent nothing on pensions programs. In 2000 governments spent about 5.5 percent of GDP on pensions programs, rising to 7.0 percent GDP in 2020.
A Century of Pensions Spending
Pensions spending by governments increased rapidly during the second half of the 20th century.

Chart 2.71: Pensions Spending in 20th Century
Government pensions spending, including both pensions for government employees and government pensions for workers, like Social Security, started out at the beginning of the 20th century at zero percent of Gross Domestic Product (GDP). Pensions increased very slowly during the first half of the century. It was only in 1931 that government pension expenditure reached 0.12 percent of GDP. By the beginning of World War II pension expenditure had doubled — all the way to 0.22 percent of GDP.
After World War II pension expenditures, now including Social Security payouts, began to accelerate, reaching 1 percent of GDP by 1953 and doubling to 2 percent of GDP by 1958. Pension expenditure reached 3 percent
of GDP by 1971 and 4 percent by 1974. Pension expenditure breached 5 percent of GDP in 1980.
The ramp-up in pensions expenditure began to moderate after 1980, reaching 5.1 percent of GDP in 1990 and 5.3 percent in 2000. Pension spending breached 6 percent of GDP in the recession year of 2009, hitting 6.39 percent of GDP in that year. Pensions expenditure was 6.8 percent of GDP in 2015, 7.1 percent of GDP in 2020.
In 2025 pensions spending is estimated at
6.76 percent GDP.
Government Pensions Before Social Security
Government spent modest amounts on pensions in the first half of the 20th Century.

Chart 2.72: Pension Spend Before Social Security
At the start of the 20th century governments spent nothing on civil pensions. This began to change right before World War I as local governments began to implement pensions programs for their employees.
Chart Key:

- Local pensions

- State pensions

- Federal pensions
After World War I the federal government and state governments started to show expenditures on pension programs for their employees. The total cost of these programs had reached 0.1 percent of GDP by 1930.
Pensions spending surged in the during the Great Depression with federal spending reaching
0.08 percent of GDP, state pension spending reaching 0.05 percent of GDP and local
government pension spending reaching 0.08 percent of GDP by 1940.
Government Pensions in the Social Security Age
Social Security dominates pension spending in the United States.

Chart 2.73: Pensions in Social Security Age
Since the passage of Social Security Act in 1935 the program has come to
dominate government pension spending.
Starting at 0.08 percent of GDP in 1940 federal pension spending reached 1.15 percent
of GDP in 1955 and 2.15 percent of GDP in 1960. In the early 1960s federal pension
spending stabilized before resuming its growth in the late 1960s, breaching 3 percent
of GDP in 1972.

The main ramp-up in Social Security spending occurred between 1965 and 1982, when federal
pension spending rose from 2 percent of GDP to 5 percent. In the years after 1980 Social
Security spending went into a modest decline, bottoming out at 4.2 percent of GDP in 2006.
But the Great Recession and the retirement of the post-World War II baby boom has reversed
that, and federal pension spending reached 5.23 percent of GDP in 2015.
in 2020 federal pension spending was 5.5 percent of GDP.
In the post-World World War II era, as Social Security spending was ramping up, the pace
of state and local pension spending remained fairly modest. But by 1991 state pension spending reached 0.5 percent of GDP and local pension spending hovered at 0.16 percent
of GDP.
By 2010 state pension spending had more than doubled to 1.15 percent of GDP and local pension spending has nearly doubled to 0.25 percent of GDP. In 2015 state pension spending was 1.29 percent
GDP and local pension spending was 0.27 percent GDP.
In 2020 state pension spending was 1.34 percent
GDP and local pension spending was 0.27 percent GDP.
Government Employee Pensions Since World War II
Government employee pension payouts amount to 2.3 percent of GDP

Chart 2.74: Government Employee Pensions
In 1950 the total payout on government employee pensions was 0.21 percent of GDP: federal at 0.09 percent,
state at 0.05 percent, and local 0.09 percent of GDP. Then they started to grow.
For three decades federal employee pension payouts dominated. Federal pensions reached 0.5 percent
GDP in 1970 and peaked at 1.03 percent of GDP in 1982, declining thereafter to 0.71 percent of GDP
in 2005. Since the mid 2000s federal pensions have increased, hitting 0.8 percent GDP in 2009, before
declining to an estimated 0.77 percent GDP in 2015.
in 2020 federal employee pensions were 0.73 percent of GDP.

In recent years, state and local government pensions have dominated. (Most states run pension plans for both their
state government and local government employees.)
State and local pension payouts reached 0.2 percent of GDP
in 1957, 0.3 percent GDP in 1964, and 0.5 percent GDP in 1982.
Then state and local pensions started to accelerate,
hitting 0.8 percent GDP in 1995 and 1.05 percent GDP in 2002.
State and local pension payouts hit 1.5 percent GDP in 2015.
In 2020 state and local employee pension payouts were 1.55 percent of GDP.
