US Fertility Rate vs Sunspot Number
US Fertility Rate and Sunspot Number correlate at r = +0.25 over 91 years (1933–2023), p = 0.016. With the time trend removed, r = +0.15. Holds up after detrending.
Verdict: Holds up after detrending. Statistically significant (p = 0.016) and the association survives trend removal (detrended r = 0.15). Correlation still isn't causation, but this one isn't an obvious artifact.
