US Adolescent Birth Rate vs US Military Expenditure
US Adolescent Birth Rate and US Military Expenditure correlate at r = +0.79 over 65 years (1960–2024), p < 0.0001. With the time trend removed, r = -0.12. 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 -0.12 — the relationship is probably coincidental, not causal.
