US Meat Consumption per Person vs US GDP per Capita

US Meat Consumption per Person and US GDP per Capita correlate at r = +0.80 over 63 years (1961–2023), p < 0.0001. With the time trend removed, r = -0.49. Direction flips without the trend.

Verdict: Direction flips without the trend. The raw correlation is 0.80, but once each series' time trend is removed it becomes -0.49. The year-to-year movements run the opposite way to the long-run trends, so the headline number is misleading.
