US Air Passengers Carried vs US Marriage Rate
US Air Passengers Carried and US Marriage Rate correlate at r = -0.87 over 52 years (1970–2022), p < 0.0001. With the time trend removed, r = +0.41. Direction flips without the trend.
Verdict: Direction flips without the trend. The raw correlation is -0.87, but once each series' time trend is removed it becomes 0.41. The year-to-year movements run the opposite way to the long-run trends, so the headline number is misleading.
