US Military Expenditure vs US Urban Population
US Military Expenditure and US Urban Population correlate at r = -0.85 over 65 years (1960–2024), p < 0.0001. With the time trend removed, r = -0.17. 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 -0.17 — the relationship is probably coincidental, not causal.
