US Milk Consumption per Person vs US College Enrollment
US Milk Consumption per Person and US College Enrollment correlate at r = -0.35 over 39 years (1971–2022), p = 0.031. With the time trend removed, r = +0.51. Direction flips without the trend.
Verdict: Direction flips without the trend. The raw correlation is -0.35, but once each series' time trend is removed it becomes 0.51. The year-to-year movements run the opposite way to the long-run trends, so the headline number is misleading.
