US Natural Gas Consumption vs US Homicide Rate

US Natural Gas Consumption and US Homicide Rate correlate at r = -0.51 over 31 years (1990–2023), p = 0.0032. With the time trend removed, r = +0.55. Direction flips without the trend.

Verdict: Direction flips without the trend. The raw correlation is -0.51, but once each series' time trend is removed it becomes 0.55. The year-to-year movements run the opposite way to the long-run trends, so the headline number is misleading.
