US Marriage Rate vs Sunspot Number
US Marriage Rate and Sunspot Number correlate at r = +0.26 over 128 years (1886–2022), p = 0.0032. With the time trend removed, r = +0.31. Holds up after detrending.
Verdict: Holds up after detrending. Statistically significant (p = 0.0032) and the association survives trend removal (detrended r = 0.31). Correlation still isn't causation, but this one isn't an obvious artifact.
