What happened to prices between 1921 and 2006
Between 1921 and 2006, the Consumer Price Index went from 17.9 to 201.6.
Cumulatively, prices increased 1026.3%, which works out to an average of
2.89% per year. Put differently, a dollar in 1921 bought what
$0.09 buys in 2006: the 1921 dollar
lost 91.1% of its purchasing power over
these 85 years.
Consumer prices fell 10.5% in 1921, the mirror image of the wartime
inflation that had more than doubled the cost of living between
1913 and 1920. The Depression of 1920-21, one
of the sharpest contractions in U.S. history, bottomed out that July
according to the National Bureau of Economic Research, even though it had
lasted barely eighteen months. Unemployment climbed toward one worker in ten
as businesses cut production and prices to work through wartime inventories,
but the same collapse in prices also meant the recovery, once it started,
had room to run without reigniting inflation. Warren Harding took office
March 4, promising a return to “normalcy” after a decade of war, pandemic,
labor unrest, and rapid price swings; his administration moved quickly to
cut top income tax rates and federal spending. Congress also acted on
immigration that year: the Emergency Quota Act, signed May 19, capped annual
arrivals from each country at 3% of that nationality’s population in the
1910 census, the first time the United States had set a numerical ceiling on
immigration. The law favored northern and western Europe and cut total
immigration by more than half compared with prewar levels; Congress
tightened the formula again in 1924. First-class postage held at 2 cents,
unchanged since mid-1919.
Every 1921 amount converts to 2006 at the same ratio, 11.26: $1,000 becomes
$11,263, and $10,000 becomes $112,626.
