US Air Passengers Carried vs US Federal Debt Outstanding
US Air Passengers Carried and US Federal Debt Outstanding correlate at r = +0.78 over 54 years (1970–2023), p < 0.0001. With the time trend removed, r = -0.43. Direction flips without the trend.
Verdict: Direction flips without the trend. The raw correlation is 0.78, but once each series' time trend is removed it becomes -0.43. The year-to-year movements run the opposite way to the long-run trends, so the headline number is misleading.
