If a country's income were a pizza shared among its people, how would the slices be cut? Explore 186 countries across six decades — and watch who gets the biggest slice.
Each pizza represents one country. It's divided into 5 slices — one for each fifth of the population, from the poorest 20% (lightest colour) to the richest 20% (darkest red). A bigger slice means that group earns a bigger share of the national income. In a perfectly equal country, every slice would be the same size.
The Gini score is a single number that summarises inequality. 0 = everyone earns the same. 100 = one person earns everything. Most countries sit between 25 and 65. Think of it as a "lopsidedness score" for the pizza — the higher the number, the more the richest slice dominates.
