Adjust the quantile to explore the impact of income inequality in countries and across time. At a quantile, calculates the representative income, for example the income of the richest 1% can be said to be at least

Purchasing power of disposable income, adjusts incomes for the relative purchasing power of goods and services in a particular country.

Use the table above to filter on countries of interest.

The implied income at a percentile is derived from the following relationship assuming an underlying log normal distribution for incomes in contries for which the mean of the distribution (average incomes) (m) and gini coefficient (G) are given by:

With these coefficients the income at a given quantile is determined by the log normal quantile function (the inverse of the CDF).
