US GDP (current US$) vs US Imports
US GDP (current US$) and US Imports correlate at r = +0.81 over 55 years (1970–2024), p < 0.0001. With the time trend removed, r = -0.59. Direction flips without the trend.
Verdict: Direction flips without the trend. The raw correlation is 0.81, but once each series' time trend is removed it becomes -0.59. The year-to-year movements run the opposite way to the long-run trends, so the headline number is misleading.
