US Infant Mortality vs US Population
US Infant Mortality and US Population correlate at r = -0.91 over 65 years (1960–2024), p < 0.0001. With the time trend removed, r = +0.61. Direction flips without the trend.
Verdict: Direction flips without the trend. The raw correlation is -0.91, but once each series' time trend is removed it becomes 0.61. The year-to-year movements run the opposite way to the long-run trends, so the headline number is misleading.
