Between 1980 and 1999, the Consumer Price Index went from 82.4 to 166.6.
Cumulatively, prices increased 102.2%, which works out to an average of
3.77% per year. Put differently, a dollar in 1980 bought what
$0.49 buys in 1999.
1980 sat at the very peak of the Great Inflation. Prices rose 13.5% in that
single year, mortgage rates were climbing toward 16%, and the Federal Reserve
under Paul Volcker was administering the painful interest-rate medicine that
would finally break the inflationary spiral, at the cost of the deep 1981–82
recession. No single year looms larger in how Americans think about inflation.
The headline number is an average. Individual categories moved very differently over this
period. Here is what $100 of 1980 spending costs in 1999, by category:
