US Median Age vs US Death Rate

US Median Age and US Death Rate correlate at r = -0.42 over 64 years (1960–2023), p = 5.3e-4. With the time trend removed, r = -0.12. Holds up after detrending.

Verdict: Holds up after detrending. Statistically significant (p = 5.3e-4) and the association survives trend removal (detrended r = -0.12). Correlation still isn't causation, but this one isn't an obvious artifact.
