US Birth Rate vs US Life Expectancy
US Birth Rate and US Life Expectancy correlate at r = -0.85 over 65 years (1960–2024), p < 0.0001. With the time trend removed, r = +0.04. 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 0.04 — the relationship is probably coincidental, not causal.
