Tokyo Average Temperature vs US Adolescent Birth Rate
Tokyo Average Temperature and US Adolescent Birth Rate correlate at r = -0.67 over 65 years (1960–2024), p < 0.0001. With the time trend removed, r = -0.03. 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 -0.03 — the relationship is probably coincidental, not causal.
