US Dollar to British Pound vs US GDP per Capita
US Dollar to British Pound and US GDP per Capita correlate at r = +0.72 over 27 years (1999–2025), p < 0.0001. With the time trend removed, r = +0.08. 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 0.08 — the relationship is probably coincidental, not causal.
