US Forest Area vs US Rural Population
US Forest Area and US Rural Population correlate at r = -0.81 over 34 years (1990–2023), p < 0.0001. With the time trend removed, r = -0.19. 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 -0.19 — the relationship is probably coincidental, not causal.
