US Adolescent Birth Rate vs US Internet Users
US Adolescent Birth Rate and US Internet Users correlate at r = -0.93 over 35 years (1990–2024), p < 0.0001. With the time trend removed, r = +0.25. Likely spurious (shared time trend).
Verdict: Likely spurious (shared time trend). Both series mostly just trend over time. After removing that trend the correlation collapses to 0.25 — the relationship is probably coincidental, not causal.
