Elon Musk on history: what the evidence says · JRE #1169
SUBJECT: HISTORY
Not a true/false call. Every claim is logged with its sources; read the exhibits below.
Manhattan had like 300,000 horses. You figure, like, if a horse lives 15 years, you've got 20,000 horses dropping dead every year if there's 300,000 horses in a 15-year lifespan.
What the evidence says 01 / RECORD
The commonly cited historical figure for Manhattan's horse population is much lower than Musk's claim. The Henry Ford museum states that 'as late as 1900, Manhattan had 130,000 horses,' compared to 74,000 in Chicago, 51,000 in Philadelphia, and 32,000 in St. Louis, roughly 2.3 times fewer than the 300,000 Musk cites. The same source notes that in the 1880s the New York City Sanitation Department was removing about 15,000 dead horses from the street each year, a real historical mortality figure in the same order of magnitude as, but below, the 20,000-per-year estimate Musk derives from his population figure. The broader point, that a large urban horse population created a substantial ongoing disposal problem before automobiles replaced horse-drawn transport, is accurate and well documented; only the specific 300,000 population figure (and the derived annual death estimate built on it) appears overstated.
