About the indicator

The share of total income or consumption that goes to the richest twenty percent of the population. Under complete equality it would be twenty percent; in the most unequal countries of Latin America and Southern Africa it comes to more than sixty. The ratio of this share to the share of the poorest quintile — the quintile ratio, S80/S20 — was historically the first measure of inequality, and it speaks more clearly than the Gini index about the gap between the poles.

Important: There are no aggregates for country groups for the same reason as with the Gini index: the quintile of a group is not a union of national quintiles. Household surveys systematically understate the incomes of the richest, so real inequality is higher than measured.
