What happened to prices between 1971 and 2007
Between 1971 and 2007, the Consumer Price Index went from 40.5 to 207.342.
Cumulatively, prices increased 412.0%, which works out to an average of
4.64% per year. Put differently, a dollar in 1971 bought what
$0.20 buys in 2007: the 1971 dollar
lost 80.5% of its purchasing power over
these 36 years.
Consumer prices rose 4.4% in 1971, down from 1970’s 5.7% as
the recession that started in December 1969 finally cooled demand. The bigger
economic story came that August 15, when President Nixon closed the “gold
window” that let foreign governments exchange dollars for gold, ending the
Bretton Woods system that had anchored the dollar since World War II. The
same address announced a 90-day freeze on wages and prices, the first
peacetime controls the country had seen, an attempt to break inflationary
expectations without the slower grind of tighter money. The “Nixon Shock,” as
it came to be known, let the dollar float against other currencies for the
first time and set the stage for a wage-and-price-control regime that would
run in various forms into 1973. Politically, the country lowered its voting
age that year: the 26th Amendment, ratified July 1, extended the vote to
18-year-olds, capping a campaign built on the argument that men old enough to
be drafted to Vietnam were old enough to vote for the people who sent them.
The Postal Service, independent since 1970’s reorganization, raised
first-class postage from 6 to 8 cents that May. A median household earned
$9,028 in 1971, up from $8,734 the year before, while gas held near 36 cents
a gallon and a new home sold for a median $25,200. Consumer prices stood
309.1% above their 1913 level by year’s end, still years away
from the double-digit inflation the controls were meant to prevent.
Every 1971 amount converts to 2007 at the same ratio, 5.12: $1,000 becomes
$5,120, and $10,000 becomes $51,196.

The destination year: 2007
In 2007, prices rose 2.8% and $100 from 1971 had the buying
power of $512; the year's average CPI of 207.342 is the level
behind every 2007 figure on this page.
Inflation was 2.8% in 2007, with gasoline averaging $2.80 a gallon, but the year is better
known for what began underneath prices. In August, French bank BNP Paribas froze funds tied to
U.S. subprime mortgages, and credit between banks tightened. The Federal Reserve responded with
a half-point cut on September 18, its first in four years, and took the policy rate from 5.25% to
4.25% by December. The economy peaked that month, by the National Bureau of Economic Research’s
dating, and the Great Recession followed. The median household earned about $50,200, and the
median new home cost $247,900. Congress ended the decade-long freeze on the federal minimum wage
in May, with the first of three steps to $5.85 in July. A first-class stamp cost 41 cents.
