US Oil Consumption vs US Federal Debt Outstanding

US Oil Consumption and US Federal Debt Outstanding correlate at r = +0.36 over 61 years (1965–2025), p = 0.0047. With the time trend removed, r = -0.56. Direction flips without the trend.

Verdict: Direction flips without the trend. The raw correlation is 0.36, but once each series' time trend is removed it becomes -0.56. The year-to-year movements run the opposite way to the long-run trends, so the headline number is misleading.
