Income Inequality (Gini) — methodology
Category: Equality & Inclusion · Unit: Gini index (0–100) · Published biennial
What this metric measures
The Gini index of household income inequality, from 0 (everyone earns the same) to 100 (one person earns everything), based on World Bank survey data.
Why it matters: Inequality shapes access to housing, health and opportunity. A rising Gini means the gap between higher and lower earners is widening.
