US Mobile Subscriptions vs US Secondary School Enrollment
US Mobile Subscriptions and US Secondary School Enrollment correlate at r = +0.59 over 29 years (1975–2022), p = 7.6e-4. With the time trend removed, r = -0.62. Direction flips without the trend.
Verdict: Direction flips without the trend. The raw correlation is 0.59, but once each series' time trend is removed it becomes -0.62. The year-to-year movements run the opposite way to the long-run trends, so the headline number is misleading.
