Brilliant! Can I steal that?
“Demography is destiny (infrequently given as demographics is destiny or demographics are destiny”) was coined by Ben Wattenberg and Richard M. Scammon in their book The Real Majority: An Extraordinary Examination of the American Electorate (1970). The authors wrote to paraphrase Heraclitus by saying, Demography is destinyHeraclitus (535 BC-475 BC) wrote character is destiny. In politics, demography is destiny means that the demographics of a population indicate which political party will carry a district.
The saying demography is destiny has been attributed to French philosopher Auguste Comte (1798-1857) since the 1980s. The word demography, however, was first cited in print in 1880. Comte (and many other writers) might have written something similar, but the authorship attribution is incorrect.
