US Secondary School Enrollment vs US Urban Population
US Secondary School Enrollment and US Urban Population correlate at r = +0.65 over 35 years (1971–2022), p < 0.0001. With the time trend removed, r = -0.42. Direction flips without the trend.
Verdict: Direction flips without the trend. The raw correlation is 0.65, but once each series' time trend is removed it becomes -0.42. The year-to-year movements run the opposite way to the long-run trends, so the headline number is misleading.
