US Nuclear Power Generation vs US Birth Rate

US Nuclear Power Generation and US Birth Rate correlate at r = -0.77 over 60 years (1965–2024), p < 0.0001. With the time trend removed, r = +0.49. Direction flips without the trend.

Verdict: Direction flips without the trend. The raw correlation is -0.77, but once each series' time trend is removed it becomes 0.49. The year-to-year movements run the opposite way to the long-run trends, so the headline number is misleading.
