US Egg Consumption per Person vs US Cereal Yield
US Egg Consumption per Person and US Cereal Yield correlate at r = -0.46 over 63 years (1961–2023), p = 1.4e-4. With the time trend removed, r = +0.59. Direction flips without the trend.
Verdict: Direction flips without the trend. The raw correlation is -0.46, but once each series' time trend is removed it becomes 0.59. The year-to-year movements run the opposite way to the long-run trends, so the headline number is misleading.
