US Marriage Rate vs US Inflation Rate

US Marriage Rate and US Inflation Rate correlate at r = +0.53 over 62 years (1960–2022), p < 0.0001. With the time trend removed, r = +0.55. Holds up after detrending.

Verdict: Holds up after detrending. Statistically significant (p = < 0.0001) and the association survives trend removal (detrended r = 0.55). Correlation still isn't causation, but this one isn't an obvious artifact.
