US Internet Usage vs US Median Age
US Internet Usage and US Median Age correlate at r = +0.97 over 34 years (1990–2023), p < 0.0001. With the time trend removed, r = +0.77. Holds up after detrending.
Verdict: Holds up after detrending. Statistically significant (p = < 0.0001) and the association survives trend removal (detrended r = 0.77). Correlation still isn't causation, but this one isn't an obvious artifact.
