US Median Age vs Worldwide Strong Earthquakes (M6+)
US Median Age and Worldwide Strong Earthquakes (M6+) correlate at r = +0.47 over 64 years (1960–2023), p < 0.0001. With the time trend removed, r = +0.29. Holds up after detrending.
Verdict: Holds up after detrending. Statistically significant (p = < 0.0001) and the association survives trend removal (detrended r = 0.29). Correlation still isn't causation, but this one isn't an obvious artifact.
