What happened to prices between 1979 and 2005
Between 1979 and 2005, the Consumer Price Index went from 72.6 to 195.3.
Cumulatively, prices increased 169.0%, which works out to an average of
3.88% per year. Put differently, a dollar in 1979 bought what
$0.37 buys in 2005: the 1979 dollar
lost 62.8% of its purchasing power over
these 26 years.
Consumer prices rose 11.3% in 1979, the fastest pace since 1947 and the
decade’s second bout of double-digit inflation after 1974’s
11.0%. The trigger was familiar: the Iranian Revolution that January halted
Iran’s oil exports, and panic buying amplified the shortage, sending crude
prices sharply higher over the year and motorists back into gas lines, with
some states reviving the odd-even rationing last seen in 1974. Paul Volcker,
appointed Federal Reserve chairman that August, responded with a strategy
shift announced that October: the Fed would target the money supply directly
and let interest rates rise as high as necessary to break inflation, whatever
the short-term cost. That cost would arrive as a deep recession in 1981-82,
but by year’s end 1979 had already delivered enough turmoil on its own. A
reactor at the Three Mile Island plant near Harrisburg, Pennsylvania,
suffered a partial core meltdown that March 28, the worst commercial nuclear
accident in U.S. history, and on November 4, militants in Tehran stormed the
U.S. embassy and took 52 Americans hostage, beginning a 444-day crisis that
consumed the rest of Carter’s presidency. A median household earned $16,461
in 1979, a new home sold for a median $62,900, and gas jumped to 86 cents a
gallon. Consumer prices finished the decade 97.8% above where they stood in
1969, very nearly doubling in ten years, and stood 633.3%
above their 1913 level. The 1970s had opened with inflation
cooling from the 1969 spike and closed with prices rising faster than at any
point since 1947, setting up the Great
Inflation’s final act in 1980.
Every 1979 amount converts to 2005 at the same ratio, 2.69: $1,000 becomes
$2,690, and $10,000 becomes $26,901.

Year by year: CPI and the value of $100 from 1979
$100 from 1979 had already become $193 by
1992, on its way to $269 in 2005; each row shows the CPI, that
year's inflation rate, and the running value.
Within the span, inflation peaked at 13.5% in 1980, and the smallest rise was 1.6% in 1998.
In 2005, prices rose 3.4% and $100 from 1979 had the buying
power of $269; the year's average CPI of 195.3 is the level
behind every 2005 figure on this page.
Inflation rose to 3.4% in 2005, up from 2.7% in 2004, as gasoline averaged $2.30 a gallon,
compared with $1.88 the year before. Hurricane Katrina made landfall on August 29, and with
Hurricane Rita weeks later it disrupted Gulf Coast refining, pushing the national average
price past $3 in early September. The Federal Reserve raised its policy rate at every meeting,
from 2.25% to 4.25%, to keep energy costs from feeding into other prices. The median household
earned about $46,300, up 4.5% from 2004, but the median new home price rose a further 9%, to
$240,900. In April, Congress passed a bankruptcy law that made it harder to clear debts. A
first-class stamp stayed at 37 cents until January 2006, and the federal minimum wage stayed
at $5.15.
