US Dollar to British Pound vs US Adult Obesity

US Dollar to British Pound and US Adult Obesity correlate at r = +0.61 over 26 years (1999–2024), p = 9.6e-4. With the time trend removed, r = -0.67. Direction flips without the trend.

Verdict: Direction flips without the trend. The raw correlation is 0.61, but once each series' time trend is removed it becomes -0.67. The year-to-year movements run the opposite way to the long-run trends, so the headline number is misleading.
