US Coal Consumption vs US Internet Users
US Coal Consumption and US Internet Users correlate at r = -0.55 over 35 years (1990–2024), p = 5.7e-4. With the time trend removed, r = +0.84. Direction flips without the trend.
Verdict: Direction flips without the trend. The raw correlation is -0.55, but once each series' time trend is removed it becomes 0.84. The year-to-year movements run the opposite way to the long-run trends, so the headline number is misleading.
