US Adult Obesity vs US GDP (current US$)
US Adult Obesity and US GDP (current US$) correlate at r = +0.94 over 45 years (1980–2024), p < 0.0001. With the time trend removed, r = -0.78. Direction flips without the trend.
Verdict: Direction flips without the trend. The raw correlation is 0.94, but once each series' time trend is removed it becomes -0.78. The year-to-year movements run the opposite way to the long-run trends, so the headline number is misleading.
