US Fertility Rate vs US Cereal Yield
US Fertility Rate and US Cereal Yield correlate at r = -0.59 over 63 years (1961–2023), p < 0.0001. With the time trend removed, r = +0.21. Holds up after detrending.
Verdict: Holds up after detrending. Statistically significant (p = < 0.0001) and the association survives trend removal (detrended r = 0.21). Correlation still isn't causation, but this one isn't an obvious artifact.
