US Birth Rate vs US Net Migration
US Birth Rate and US Net Migration correlate at r = -0.61 over 65 years (1960–2024), p < 0.0001. With the time trend removed, r = +0.21. 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 0.21 — the relationship is probably coincidental, not causal.
