US Annual Working Hours per Worker vs US GDP (current US$)
US Annual Working Hours per Worker and US GDP (current US$) correlate at r = -0.72 over 64 years (1960–2023), p < 0.0001. With the time trend removed, r = +0.45. Direction flips without the trend.
Verdict: Direction flips without the trend. The raw correlation is -0.72, but once each series' time trend is removed it becomes 0.45. The year-to-year movements run the opposite way to the long-run trends, so the headline number is misleading.
