US Life Expectancy vs US Secondary School Enrollment
US Life Expectancy and US Secondary School Enrollment correlate at r = +0.76 over 35 years (1971–2022), p < 0.0001. With the time trend removed, r = +0.28. 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 0.28 — the relationship is probably coincidental, not causal.
