Worldwide Major Earthquakes (M5+) vs US Birth Rate
Worldwide Major Earthquakes (M5+) and US Birth Rate correlate at r = -0.77 over 65 years (1960–2024), p < 0.0001. With the time trend removed, r = -0.44. Holds up after detrending.
Verdict: Holds up after detrending. Statistically significant (p = < 0.0001) and the association survives trend removal (detrended r = -0.44). Correlation still isn't causation, but this one isn't an obvious artifact.
