The index is calculated from the Lorenz curve, in which cumulative family income is plotted against the number of families arranged from the poorest to the ric. The Gini coefficient G is the area of the grey section of the Lorenz curve divided by the sum of the red and grey areas. If everyone has the same income, then it 31 Jan 2014 The Gini index, which is calculated by the U.S. Census Bureau, is a statistical measure of income distribution within a given area. Indexes The results suggest that the value of 0.4 is around the mean of the Gini coefficients, corresponding to the most probable event in a peaceful world, rather than the gini.

Definition of Gini Coefficient: Gini coefficient, the most general method for measuring the income distribution, was developed by Italian 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, 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. It was developed by the Italian statistician and sociologist Corrado Gini and published in his 1912 paper Variability and Mutability. The Gini coefficient measures the inequality among values of a frequency distribution. A Gini coefficient
Gini index or entropy is the criterion for calculating information gain. Both gini and entropy are measures of impurity of a node. A node having multiple classes is impure whereas a node having only one class is pure. Entropy in statistics is analogous to entropy in thermodynamics where it signifies disorder.
