US Air Passengers Carried vs US Milk Consumption per Person

US Air Passengers Carried and US Milk Consumption per Person correlate at r = -0.29 over 54 years (1970–2023), p = 0.036. With the time trend removed, r = +0.26. Holds up after detrending.

Verdict: Holds up after detrending. Statistically significant (p = 0.036) and the association survives trend removal (detrended r = 0.26). Correlation still isn't causation, but this one isn't an obvious artifact.
