US Coal Consumption vs US Median Age
US Coal Consumption and US Median Age correlate at r = +0.34 over 59 years (1965–2023), p = 0.0081. With the time trend removed, r = +0.80. Holds up after detrending.
Verdict: Holds up after detrending. Statistically significant (p = 0.0081) and the association survives trend removal (detrended r = 0.80). Correlation still isn't causation, but this one isn't an obvious artifact.
