US CO₂ Emissions per Capita vs US Fertility Rate
US CO₂ Emissions per Capita and US Fertility Rate correlate at r = -0.25 over 91 years (1933–2023), p = 0.016. With the time trend removed, r = -0.03. Holds up after detrending.
Verdict: Holds up after detrending. Statistically significant (p = 0.016) and the association survives trend removal (detrended r = -0.03). Correlation still isn't causation, but this one isn't an obvious artifact.
