US Fertility Rate vs US Mobile Subscriptions
US Fertility Rate and US Mobile Subscriptions correlate at r = -0.36 over 49 years (1960–2023), p = 0.011. With the time trend removed, r = +0.49. Direction flips without the trend.
Verdict: Direction flips without the trend. The raw correlation is -0.36, 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.
