Between 1921 and 1941, the Consumer Price Index went from 17.9 to 14.7.
Cumulatively, prices declined 17.9%, which works out to an average of
-0.98% per year. Put differently, a dollar in 1921 bought what
$1.22 buys in 1941.
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.
The headline number is an average. Individual categories moved very differently over this
period. Here is what $100 of 1921 spending costs in 1941, by category:
Category
Avg. yearly inflation
$100 in 1921 →
All items (CPI-U)
-0.98%
$82.12
Food
-0.96%
$82.39
Apparel
-1.86%
$68.67
Not shown because the BLS began these indexes after 1921: core (all items less food & energy) (1957–), energy (1957–), housing (1967–), medical care (1935–), transportation (1935–), recreation (1993–), education & communication (1993–).
Consumer prices rose 5.0% in 1941, up sharply from just 0.7% in
1940 and the fastest annual increase since 1920, as
rearmament and Lend-Lease production pushed demand well ahead of peacetime
supply even before the United States formally joined the war. Congress had
already tilted the country away from neutrality that March, passing the
Lend-Lease Act to arm Britain, and later the Soviet Union and other Allies,
without requiring immediate payment. That April, the government created the
Office of Price Administration to hold down the cost of civilian goods, the
start of a price-control system that would keep official inflation numbers
well below what wartime demand alone would have produced over the next four
years. Then, on December 7, Japan attacked the naval base at Pearl Harbor,
destroying much of the Pacific Fleet and killing more than 2,400 Americans.
Congress declared war on Japan the next day and on Germany and Italy three
days later, ending years of debate over whether the United States should
stay out of the conflict spreading across Europe and Asia. Consumer prices,
already up 48.5% from their 1913 level, would climb far
faster over the next two years as the economy converted fully to war
production. First-class postage held at 3 cents, and the minimum wage stayed
at 30 cents an hour.
