The Gini Index is the indicator par excellence, used to measure the level of distribution of monetary income and derived from social inequality. However, when  24 Feb 2010 One way to measure income equality is the Gini Coefficient. If A = 0, it means the Lorenz Curve is actually the Line of Equality. 30% of the population earns 15% of the income, while the top 30% earns 45% of the income. The Gini Index can be used to quantify the unevenness in variable distributions, as well as income distributions The maximum Gini Index = 1 would mean that all the income belongs to one country. 30, 2. 50, 4. 60, 5. 90, 4. 100, 3. 120, 2  FAO's Web site for educational or other non-commercial purposes are authorized without In order to capture the meaning of the generalised Gini Index, let us just recall the The Measurement of Inequality of Incomes, Economic Journal, 30,.

In the case of a mean preserving transfer, one from the highest income When the original Gini index is .50 (.30), this implies that as long as the recipient is  inequality analysis should be performed on a set of indicators or by means of a comparison of the Gini coefficient. Although the Gini coefficient has many good properties, it does not lend itself well to with only 30% of the actual total wealth.

Since many distributions of incomes are skewed to the right, the mean often exceeds the median and q(p = 0.5)/µ will typically be less than one. The convexity of

The Gini index is a simple measure of the distribution of income across income percentiles in a population. A higher Gini index indicates greater inequality, with high income individuals receiving much larger percentages of the total income of the population. In economics, the Gini coefficient (/ ˈ dʒ iː n i / JEE-nee), sometimes called the Gini index or Gini ratio, is a measure of statistical dispersion intended to represent the income or wealth distribution of a nation's residents, and is the most commonly used measurement of inequality. The Gini Index is a summary measure of income inequality. The Gini coefficient incorporates the detailed shares data into a single statistic, which summarizes the dispersion of income across the entire income distribution. The Gini index (i.e. the Gini coefficient) is a statistical measure of distribution, developed by Corrado Gini in 1912. In an economic context it is commonly used as an index of economic inequality that measures income or wealth distribution among the population. The Gini coefficient for disposable income is typically lower, between 0.3 and 0.5, and is about 0.45 in the United States and 0.30 in Denmark. The meaning of the Gini coefficient can be best understood by looking at Figures 11 and 12, which show plots of the percentage of the total wealth of a population owned by a given percentage of the Definition of Gini index: Standard economic measure of income inequality, based on Lorenz Curve. A society that scores 0.0 on the Gini scale has perfect equality in income distribution. Higher the number over 0 higher the The Gini index or Gini coefficient is a statistical measure of distribution which was developed by the Italian statistician Corrado Gini in 1912.
