Mean years of schooling vs Gini coefficient, 2000–2020. Dot trails show 5-year trajectory. Fixed curve = structural relationship.
Regional breakdown — hollow = 2000, filled = current year
* Gini values between observed survey years are linearly interpolated. Dashed borders indicate interpolated data points. Annotations appear only for years where observed data exists.
**Americas: Most countries sit above curve, inequality persists despite high schooling
