US Annual Working Hours per Worker vs US Population Aged 65+
US Annual Working Hours per Worker and US Population Aged 65+ correlate at r = -0.80 over 64 years (1960–2023), p < 0.0001. With the time trend removed, r = -0.13. 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 -0.13 — the relationship is probably coincidental, not causal.
