This simplifies the mathematical explanation of the gini coefficient, which is A/(A+B) ... 1=Gini coefficient diagram, based on the version by Bluemoose/BenFrantzDale ...
The Italian statistician Corrado Gini developed the Gini coefficient and published it in his 1912 paper Variabilità e mutabilità (English: variability and mutability). [16] [17] Building on the work of American economist Max Lorenz, Gini proposed using the difference between the hypothetical straight line depicting perfect equality and the actual line depicting people's incomes as a measure ...
Gini coefficient diagram. You can think of the horizontal axis as percent of people and the vertical axis as the percent of income those people receive. Therefore the curves always start and end at the same places, where 0% of people make 0% of the country's income and 100% of people making 100% of the total income.
A complete handout about the Lorenz curve including various applications, including an Excel spreadsheet graphing Lorenz curves and calculating Gini coefficients as well as coefficients of variation. LORENZ 3.0 is a Mathematica notebook which draw sample Lorenz curves and calculates Gini coefficients and Lorenz asymmetry coefficients from data ...
The Gini coefficient is a measure of the deviation of the Lorenz curve from the equidistribution line which is a line connecting [0, 0] and [1, 1], which is shown in black (α = ∞) in the Lorenz plot on the right. Specifically, the Gini coefficient is twice the area between the Lorenz curve and the equidistribution line.
English: When the richest u % of the population (red) equally share f % of all income or wealth, and the others (green) equally share the remainder, the Gini coefficient is f − u. A smooth distribution (blue) with the same characteristics will always have a larger Gini coefficient.
It is defined as a ratio with values between 0 and 1: A low Gini coefficient indicates more equal income or wealth distribution, while a high Gini coefficient indicates more unequal distribution. 0 corresponds to perfect equality (everyone having exactly the same income) and 1 corresponds to perfect inequality (where one person has all the ...
