US Median Age vs US Solar Energy Consumption
US Median Age and US Solar Energy Consumption correlate at r = +0.62 over 41 years (1983–2023), p < 0.0001. With the time trend removed, r = -0.55. 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 -0.55. The year-to-year movements run the opposite way to the long-run trends, so the headline number is misleading.
