US Death Rate vs US Health Expenditure

US Death Rate and US Health Expenditure correlate at r = +0.51 over 24 years (2000–2023), p = 0.011. With the time trend removed, r = -0.16. Holds up after detrending.

Verdict: Holds up after detrending. Statistically significant (p = 0.011) and the association survives trend removal (detrended r = -0.16). Correlation still isn't causation, but this one isn't an obvious artifact.
