US Population Aged 65+ vs US Secondary School Enrollment
US Population Aged 65+ and US Secondary School Enrollment correlate at r = +0.76 over 35 years (1971–2022), p < 0.0001. With the time trend removed, r = +0.22. 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 0.22 — the relationship is probably coincidental, not causal.
