US Egg Consumption per Person vs US Fertility Rate

US Egg Consumption per Person and US Fertility Rate correlate at r = +0.67 over 63 years (1961–2023), p < 0.0001. With the time trend removed, r = +0.46. Holds up after detrending.

Verdict: Holds up after detrending. Statistically significant (p = < 0.0001) and the association survives trend removal (detrended r = 0.46). Correlation still isn't causation, but this one isn't an obvious artifact.
