US Natural Gas Consumption vs US Annual Working Hours per Worker

US Natural Gas Consumption and US Annual Working Hours per Worker correlate at r = -0.53 over 59 years (1965–2023), p < 0.0001. With the time trend removed, r = +0.32. Direction flips without the trend.

Verdict: Direction flips without the trend. The raw correlation is -0.53, but once each series' time trend is removed it becomes 0.32. The year-to-year movements run the opposite way to the long-run trends, so the headline number is misleading.
