US Marriage Rate vs US Life Expectancy
US Marriage Rate and US Life Expectancy correlate at r = -0.73 over 62 years (1960–2022), p < 0.0001. With the time trend removed, r = +0.38. Direction flips without the trend.
Verdict: Direction flips without the trend. The raw correlation is -0.73, but once each series' time trend is removed it becomes 0.38. The year-to-year movements run the opposite way to the long-run trends, so the headline number is misleading.
