Value of $100 in 1924, adjusted to 1975

What happened to prices between 1924 and 1975

Between 1924 and 1975, the Consumer Price Index went from 17.1 to 53.8. Cumulatively, prices increased 214.6%, which works out to an average of 2.27% per year. Put differently, a dollar in 1924 bought what $0.32 buys in 1975.

Consumer prices held flat in 1924, the CPI’s annual average unchanged from 1923 after swinging from a sharp postwar drop to a modest rise the year before. That stability, extending the calm that had settled in after the deflation of 1921 and 1922, became a defining feature of the rest of the decade. Congress tightened immigration policy further with the Immigration Act of 1924, signed May 26, which cut the national-origins quota from 3% of each nationality’s 1910 census population to 2% of its 1890 population, shifting admissions further toward northern and western Europe and effectively excluding most immigration from Asia. Abroad, the U.S.-backed Dawes Plan, adopted that August, reorganized Germany’s war reparations payments and opened the way for American loans into the German economy, helping stabilize European currencies after the hyperinflation that had peaked in 1923. At home, Calvin Coolidge, who had served out the remainder of Warren Harding’s term after his death the previous year, won a full term of his own that November, campaigning on continued prosperity and limited government. First-class postage remained at 2 cents, a price unchanged since mid-1919.

The destination year: 1975

Consumer prices rose 9.1% in 1975, easing slightly from 1974’s 11.0% but still running far above anything the country had experienced before the decade began. The recession that started in November 1973, the deepest since the Great Depression, bottomed out that March, yet unemployment kept climbing through the year and touched 9%, a combination of high inflation and high joblessness that had no precedent in the postwar data. Vietnam ended that April 30, when North Vietnamese forces captured Saigon and the last Americans were evacuated by helicopter from the U.S. embassy roof. Fiscal strain hit closer to home too: New York City, facing bankruptcy after years of borrowing to paper over budget gaps, asked Washington for help that October. President Ford’s initial refusal produced the Daily News headline “Ford to City: Drop Dead,” though he ultimately signed a federal loan package that December. Amid the gloom, Bill Gates and Paul Allen founded Microsoft that April in Albuquerque, New Mexico, to sell a version of the BASIC programming language for the Altair 8800, one of the first personal computers sold to hobbyists. A median household earned $11,800 in 1975, a new home sold for a median $39,300, and first-class postage held at 10 cents, unchanged since 1974’s increase. Consumer prices stood 443.4% above their 1913 level, with the decade barely past its midpoint.
