What happened to prices between 1934 and 1991
Between 1934 and 1991, the Consumer Price Index went from 13.4 to 136.2.
Cumulatively, prices increased 916.4%, which works out to an average of
4.15% per year. Put differently, a dollar in 1934 bought what
$0.10 buys in 1991: the 1934 dollar
lost 90.2% of its purchasing power over
these 57 years.
Consumer prices rose 3.1% in 1934, the first annual increase since 1926;
every year from 1927 through 1933 had been flat or falling,
so the turn marked a real break after eight years without a single gain.
Currency policy did some of the work. The Gold Reserve Act, signed January
30, formally devalued the dollar by raising the official price of gold from
$20.67 to $35 an ounce, part of the administration’s deliberate effort to
reflate prices after four straight years of deflation. Financial regulation
tightened at the same time: the Securities Exchange Act of June 6 created
the Securities and Exchange Commission to police stock exchanges and enforce
disclosure rules, a direct response to the speculation blamed for the 1929
crash. The recovery was fragile and unevenly felt, especially on the Great
Plains, where drought had turned overplowed farmland to dust. Over May 9-11,
high winds lifted an estimated 350 million tons of topsoil into the air,
darkening skies as far away as Washington and New York and giving city
readers who had never seen a wheat field a first glimpse of the disaster
building in Kansas, Oklahoma, and Texas. Consumer prices stood 35.4% above
their 1913 level, still well below the 1929 peak but rising
for the first time since the Depression began. First-class postage held at
3 cents.
Every 1934 amount converts to 1991 at the same ratio, 10.16: $1,000 becomes
$10,164, and $10,000 becomes $101,642.

Year by year: CPI and the value of $100 from 1934
$100 from 1934 had already become $225 by
1962, on its way to $1,016 in 1991; each row shows the CPI, that
year's inflation rate, and the running value.
Within the span, inflation peaked at 14.4% in 1947, and prices fell 2.1% in 1938, the deepest deflation of the period.
Long periods are sampled every 2 years; the calculator above covers any pair of years.
The destination year: 1991
In 1991, prices rose 4.2% and $100 from 1934 had the buying
power of $1,016; the year's average CPI of 136.2 is the level
behind every 1991 figure on this page.
1991 opened in recession and closed in a slow, uneven recovery. The median household earned
about $30,100 for the year, gas averaged $1.14 a gallon, and a new home cost roughly $120,000.
Inflation ran at 4.2% for the year, down from 1990’s oil-driven spike, as the Gulf War ended in
February and crude oil retreated from its autumn highs. The recession itself, dated by the
National Bureau of Economic Research from July 1990 to March 1991, was technically over by
spring, but hiring stayed weak well into 1992, the stretch economists came to call the jobless
recovery. The Federal Reserve kept cutting interest rates through the year to support growth,
reversing the tightening campaign it had run through the late 1980s. In April the federal
minimum wage rose to $4.25 an hour, the second step of an increase from the $3.35 rate that had
held since 1981. The Postal Service had already raised the cost of a first-class stamp to 29
cents that February. It was the first full year of the decade without an oil shock driving
prices, even if the job market took longer to follow.
