US Internet Usage vs US Milk Consumption per Person
US Internet Usage and US Milk Consumption per Person correlate at r = -0.64 over 34 years (1990–2023), p < 0.0001. With the time trend removed, r = +0.57. Direction flips without the trend.
Verdict: Direction flips without the trend. The raw correlation is -0.64, but once each series' time trend is removed it becomes 0.57. The year-to-year movements run the opposite way to the long-run trends, so the headline number is misleading.
