US Solar Energy Consumption vs US Infant Mortality

US Solar Energy Consumption and US Infant Mortality correlate at r = -0.51 over 42 years (1983–2024), p = 6.1e-4. With the time trend removed, r = +0.71. Direction flips without the trend.

Verdict: Direction flips without the trend. The raw correlation is -0.51, but once each series' time trend is removed it becomes 0.71. The year-to-year movements run the opposite way to the long-run trends, so the headline number is misleading.
