US Nuclear Power Generation vs US Mobile Subscriptions

US Nuclear Power Generation and US Mobile Subscriptions correlate at r = +0.74 over 49 years (1965–2024), p < 0.0001. With the time trend removed, r = -0.62. Direction flips without the trend.

Verdict: Direction flips without the trend. The raw correlation is 0.74, 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.
