Featured correlations

Some findings that surprise

r = −0.87
India · Toilet access × Child stunting
Open defecation is a stronger predictor of child malnutrition than income or education — even after controlling for poverty.
NFHS-5 2019–21 · 28 Indian states
r = −0.79
EU · Gini inequality × Life expectancy
More equal EU societies live significantly longer. Bulgaria has both the highest inequality and the shortest life expectancy in the bloc.
Eurostat 2022 · 27 EU member states
r = −0.89
India · Female literacy × Fertility rate
States where women finish school have dramatically fewer children — literacy is the most powerful predictor of fertility in the dataset.
NFHS-5 2019–21 · 28 Indian states
r = −0.81
EU · Renewable energy × CO₂ per capita
The green transition works — but France's nuclear fleet means it achieves low CO₂ with a modest renewables share that misleads the headline number.
EEA 2021 · Eurostat 2022 · 27 EU countries
r = +0.74
History · Trade reach × Cultural output
Civilizations with wider trade networks consistently scored higher on cultural output — from Abbasid Baghdad to the Dutch Republic. Openness drives ideas.
