US Egg Consumption per Person vs US GDP (current US$)

US Egg Consumption per Person and US GDP (current US$) correlate at r = -0.38 over 63 years (1961–2023), p = 0.0022. With the time trend removed, r = +0.87. Direction flips without the trend.

Verdict: Direction flips without the trend. The raw correlation is -0.38, but once each series' time trend is removed it becomes 0.87. The year-to-year movements run the opposite way to the long-run trends, so the headline number is misleading.
