London Average Temperature vs US Fertility Rate
London Average Temperature and US Fertility Rate correlate at r = -0.40 over 64 years (1960–2023), p = 0.0012. With the time trend removed, r = +0.15. Holds up after detrending.
Verdict: Holds up after detrending. Statistically significant (p = 0.0012) and the association survives trend removal (detrended r = 0.15). Correlation still isn't causation, but this one isn't an obvious artifact.
