US GDP per Capita vs US Military Expenditure
US GDP per Capita and US Military Expenditure correlate at r = -0.78 over 65 years (1960–2024), p < 0.0001. With the time trend removed, r = +0.52. Direction flips without the trend.
Verdict: Direction flips without the trend. The raw correlation is -0.78, but once each series' time trend is removed it becomes 0.52. The year-to-year movements run the opposite way to the long-run trends, so the headline number is misleading.
