US Imports vs US Population Aged 65+

US Imports and US Population Aged 65+ correlate at r = +0.67 over 55 years (1970–2024), p < 0.0001. With the time trend removed, r = -0.77. Direction flips without the trend.

Verdict: Direction flips without the trend. The raw correlation is 0.67, but once each series' time trend is removed it becomes -0.77. The year-to-year movements run the opposite way to the long-run trends, so the headline number is misleading.
