US Marriage Rate vs US Solar Energy Consumption
US Marriage Rate and US Solar Energy Consumption correlate at r = -0.62 over 39 years (1983–2022), p < 0.0001. With the time trend removed, r = +0.31. Direction flips without the trend.
Verdict: Direction flips without the trend. The raw correlation is -0.62, but once each series' time trend is removed it becomes 0.31. The year-to-year movements run the opposite way to the long-run trends, so the headline number is misleading.
