What happened to prices between 1965 and 1990
Between 1965 and 1990, the Consumer Price Index went from 31.5 to 130.7.
Cumulatively, prices increased 314.9%, which works out to an average of
5.86% per year. Put differently, a dollar in 1965 bought what
$0.24 buys in 1990: the 1965 dollar
lost 75.9% of its purchasing power over
these 25 years.
Consumer prices rose 1.6% in 1965, up from 1964’s 1.3% in a
pickup that economists later mark as the start of the Great
Inflation, a run of accelerating
price increases driven by rising Vietnam War spending layered on top of
new Great Society programs. The war itself escalated on the ground that
March, when about 3,500 Marines came ashore at Da Nang, the first American
combat troops committed to Vietnam; troop levels would climb toward
200,000 by year’s end. Domestic policy expanded just as fast: Medicare and
Medicaid became law that July 30, creating federal health insurance for
older and low-income Americans, and the Voting Rights Act, signed that
August 6, banned literacy tests and other devices used to disenfranchise
Black voters. The civil rights movement’s gains coexisted with urban
unrest that same August, when a highway patrol traffic stop in the Watts
neighborhood of Los Angeles set off six days of rioting that left 34
people dead. Consumer prices finished 1965 218.2% above their
1913 level. First-class postage held at 5 cents, and the
minimum wage stayed at $1.25 an hour.
Every 1965 amount converts to 1990 at the same ratio, 4.15: $1,000 becomes
$4,149, and $10,000 becomes $41,492.

Year by year: CPI and the value of $100 from 1965
$100 from 1965 had already become $192 by
1977, on its way to $415 in 1990; each row shows the CPI, that
year's inflation rate, and the running value.
Within the span, inflation peaked at 13.5% in 1980, and the smallest rise was 1.9% in 1986.
In 1990, prices rose 5.4% and $100 from 1965 had the buying
power of $415; the year's average CPI of 130.7 is the level
behind every 1990 figure on this page.
In 1990, the median U.S. household earned about $29,900, gas averaged $1.15 a
gallon, and mailing a letter cost a quarter. Inflation ran hot at 5.4% for the
year, its highest rate since 1982, pushed up by an oil shock after Iraq’s
invasion of Kuwait, and the economy tipped into recession that summer. It was
the last gasp of elevated inflation before the long calm of the 1990s.
