US Marriage Rate vs US Infant Mortality
US Marriage Rate and US Infant Mortality correlate at r = +0.58 over 62 years (1960–2022), p < 0.0001. With the time trend removed, r = -0.83. Direction flips without the trend.
Verdict: Direction flips without the trend. The raw correlation is 0.58, but once each series' time trend is removed it becomes -0.83. The year-to-year movements run the opposite way to the long-run trends, so the headline number is misleading.
