US Infant Mortality vs US Secondary School Enrollment

US Infant Mortality and US Secondary School Enrollment correlate at r = -0.85 over 35 years (1971–2022), p < 0.0001. With the time trend removed, r = -0.63. Holds up after detrending.

Verdict: Holds up after detrending. Statistically significant (p = < 0.0001) and the association survives trend removal (detrended r = -0.63). Correlation still isn't causation, but this one isn't an obvious artifact.
