Brazil - GINI index. GINI index (World Bank estimate) The value for GINI index (World Bank estimate) in Brazil was 52.87 as of 2013. As the graph below shows, over the past 32 years this indicator reached a maximum value of 63.30 in 1989 and a minimum value of 52.67 in 2012.
The Gini coefficient measures the inequality among values of a frequency distribution (for example, levels of income). A Gini coefficient of zero expresses perfect equality, where all values are the same (for example, where everyone has the same income).A Gini coefficient of one (or 100%) expresses maximal inequality among values (for example, where only one person has all the income or consumption, and all others have none).s another example, in a population where the lowest 50% of individuals have no income and the other 50% have equal income, the Gini coefficient is 0.5; whereas for another population where the lowest 75% of people have 25% of income and the top 25% have 75% of the income, the Gini index is also 0.5.
