US Air Passengers Carried vs US GDP (current US$)
US Air Passengers Carried and US GDP (current US$) correlate at r = +0.89 over 54 years (1970–2023), p < 0.0001. With the time trend removed, r = -0.21. Likely spurious (shared time trend).
Verdict: Likely spurious (shared time trend). Both series mostly just trend over time. After removing that trend the correlation collapses to -0.21 — the relationship is probably coincidental, not causal.
