US Median Age vs US Exports
US Median Age and US Exports correlate at r = +0.85 over 54 years (1970–2023), p < 0.0001. With the time trend removed, r = +0.14. 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 0.14 — the relationship is probably coincidental, not causal.
