Value of $100 in 1925, adjusted to 1975

What happened to prices between 1925 and 1975

Between 1925 and 1975, the Consumer Price Index went from 17.5 to 53.8. Cumulatively, prices increased 207.4%, which works out to an average of 2.27% per year. Put differently, a dollar in 1925 bought what $0.33 buys in 1975.

Consumer prices rose 2.3% in 1925, the CPI’s largest single-year increase since the deflationary swings of the early 1920s, though still mild next to the double-digit inflation of the World War I years. The country’s cultural fault lines were on full display that summer in Dayton, Tennessee, where high school teacher John Scopes was tried July 10-21 for violating a state law against teaching evolution, a case that drew national press coverage and pitted prosecutor William Jennings Bryan against defense attorney Clarence Darrow. Real estate speculation, meanwhile, peaked in Florida, where buyers flipped undeveloped land in the Miami area on thin down payments, driving prices far above what the land itself could support; the bubble would collapse the following year. Detroit reshuffled that June too: Walter Chrysler reorganized the struggling Maxwell Motor Company into Chrysler Corporation, the start of what would become one of the American auto industry’s “Big Three.” First-class postage held at 2 cents for the sixth straight year.

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.
