This is a list of countries and territories by income inequality metrics, as calculated by the World Bank, UNU-WIDER, OCDE, and World Inequality Database, based on different indicators, like Gini coefficient and specific income ratios.
In recent decades, there has been a modest decline in inequality for the country as a whole. Brazil's GINI coefficient, a measure of income inequality, has slowly decreased from 0.596 in 2001 to 0.543 in 2009. [3] However, the numbers still point to a rather significant problem of income disparity.

[6] [7] [8] * indicates "Wealth inequality in COUNTRY or TERRITORY" or "Income inequality in COUNTRY or TERRITORY ...
Brazil ranks among the world's highest nations in the Gini coefficient index of inequality assessment. A study on the subject [6] shows that the poor segment constitutes roughly one third of the population, and the extremely poor make out 13% (2005 figures). However, the same study shows the income growth of the poorest 20% population segment ...
