Not shown because the BLS began these indexes after 1973: recreation (1993–), education & communication (1993–).
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.
