Between 1925 and 1980, the Consumer Price Index went from 17.5 to 82.4.
Cumulatively, prices increased 370.9%, which works out to an average of
2.86% per year. Put differently, a dollar in 1925 bought what
$0.21 buys in 1980.
Consumer prices rose 2.3% in 1925, the CPI’s largest single-year increase
since the deflationary swings of the early 1920s, though still mild next to
the double-digit inflation of the World War I years. The country’s cultural
fault lines were on full display that summer in Dayton, Tennessee, where
high school teacher John Scopes was tried July 10-21 for violating a state
law against teaching evolution, a case that drew national press coverage and
pitted prosecutor William Jennings Bryan against defense attorney Clarence
Darrow. Real estate speculation, meanwhile, peaked in Florida, where buyers
flipped undeveloped land in the Miami area on thin down payments, driving
prices far above what the land itself could support; the bubble would
collapse the following year. Detroit reshuffled that June too: Walter
Chrysler reorganized the struggling Maxwell Motor Company into Chrysler
Corporation, the start of what would become one of the American auto
industry’s “Big Three.” First-class postage held at 2 cents for the sixth
straight year.
The headline number is an average. Individual categories moved very differently over this
period. Here is what $100 of 1925 spending costs in 1980, by category:
Category
Avg. yearly inflation
$100 in 1925 →
All items (CPI-U)
2.86%
$471
Food
3.06%
$526
Apparel
2.28%
$346
Not shown because the BLS began these indexes after 1925: core (all items less food & energy) (1957–), energy (1957–), housing (1967–), medical care (1935–), transportation (1935–), recreation (1993–), education & communication (1993–).
Long periods are sampled every 2 years; the calculator above covers any pair of years.
The destination year: 1980
1980 sat at the very peak of the Great Inflation. Prices rose 13.5% in that
single year, mortgage rates were climbing toward 16%, and the Federal Reserve
under Paul Volcker was administering the painful interest-rate medicine that
would finally break the inflationary spiral, at the cost of the deep 1981–82
recession. No single year looms larger in how Americans think about inflation.
