US Dollar to British Pound vs US Median Age
US Dollar to British Pound and US Median Age correlate at r = +0.67 over 25 years (1999–2023), p = 2.5e-4. With the time trend removed, r = -0.30. 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 -0.30 — the relationship is probably coincidental, not causal.
