About the indicator

The share of total income or consumption that goes to the poorest twenty percent of the population. Under complete equality it would be twenty percent; in the most equal countries it comes to about nine, in the most unequal to about three. The indicator reads more plainly than the Gini index: instead of collapsing the whole distribution into a single number, it says outright how much goes to those who get the least.

Important: There are no aggregates for country groups: the top and bottom quintiles of a group are not a union of national quintiles, and they cannot be computed from country shares. The same reason as with the Gini index.
