US Energy Use per Capita vs US College Enrollment
US Energy Use per Capita and US College Enrollment correlate at r = -0.55 over 39 years (1971–2022), p = 3.2e-4. With the time trend removed, r = +0.43. Direction flips without the trend.
Verdict: Direction flips without the trend. The raw correlation is -0.55, but once each series' time trend is removed it becomes 0.43. The year-to-year movements run the opposite way to the long-run trends, so the headline number is misleading.
