US Milk Consumption per Person vs US Health Expenditure
US Milk Consumption per Person and US Health Expenditure correlate at r = -0.77 over 24 years (2000–2023), p < 0.0001. With the time trend removed, r = -0.23. 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 -0.23 — the relationship is probably coincidental, not causal.
