US GDP per Capita vs US Health Expenditure
US GDP per Capita and US Health Expenditure correlate at r = +0.79 over 24 years (2000–2023), p < 0.0001. With the time trend removed, r = -0.69. Direction flips without the trend.
Verdict: Direction flips without the trend. The raw correlation is 0.79, but once each series' time trend is removed it becomes -0.69. The year-to-year movements run the opposite way to the long-run trends, so the headline number is misleading.
