Gini coefficient chart
Relationship between AUC and Gini Coefficient Gini = 2*AUC - 1. You must be wondering how they are related. If you reverse the axis of chart shown in the above section named "Gini Coefficient", you would get similar to the chart below. Here Gini = B / (A + B). Area of A + B is 0.5 so Gini = B / 0.5 which simplifies to Gini = 2*B. China’s Gini Coefficient data was reported at 0.468 NA in Dec 2018. This records an increase from the previous number of 0.467 NA for Dec 2017. China’s Gini Coefficient data is updated yearly, averaging 0.475 NA from Dec 2003 to 2018, with 16 observations. The data reached an all-time high of 0.491 NA in 2008 and a record low of 0.462 NA in 2015. The Gini index measures the area between the Lorenz curve and a hypothetical line of absolute equality, expressed as a percentage of the maximum area under the line. Thus a Gini index of 0 represents perfect equality, while an index of 100 implies perfect inequality. Historical Income Tables: Income Inequality. Table A-4. Selected Measures of Household Income Dispersion Selected Measures of Household Income Dispersion: 1967 to 2018 [<1.0 MB Table F-4. Gini Ratios of Families by Race and Hispanic Origin of Householder The World Factbook ABOUT. History Distribution of family income - Gini index measures the degree of inequality in the distribution of family income in a country. The more nearly equal a country's income distribution, the lower its Gini index, e.g., a Scandinavian country with an index of 25. The more unequal a country's income distribution
21 Feb 2013 According to Today, "some countries compute their Gini coefficients based on I had superimposed Singapore's statistics into the chart below.
23 Oct 2012 Gini coefficient, one measure of economic inequality. There's a fascinating chart produced by The Economist showing the global Gini index This Gini coefficient calculator can be employed for swift and simple computations of the Gini coefficient for any specified income distribution. How to use the calculator: Enter a set of incomes separated by commas, line breaks, or spaces, and click on the "Calculate" button. Gini Coefficient above 60% is a good Model. Gini= A U-A L / A U Gini checks the predictive power of a credit risk model, the degree at which the model has a better discrimination power that random values. Lift Chart. Lift curve is the plot between total lift and %population. The Gini coefficient is a single number aimed at measuring the degree of inequality in a distribution. It is most often used in economics to measure how far a country's wealth or income distribution deviates from a totally equal distribution. What happens to the Gini coefficient as I add many higher-income people? Compare the Lorenz curves for the populations [10, 20, 35, 35] and [15, 15, 30, 40]. Their Gini coefficients are the same, but I think that this is a weakness of the index–I think the latter is a more equitable income distribution.
12 Oct 2017 Show graph details Download chart. Print The Gini coefficient for wealth in London is 0.67, compared with 0.61 in Great Britain as a whole.
Label each Lorenz curve with its corresponding Gini coefficient, and check that the coefficients are consistent with what you see in your charts. (Hint: In the Gini Gini coefficient inequality measure using income (BHC), 1961 - 2017-18 (GB) Gini coefficient income inequality graph (IMAGE/PNG); Gini coefficient income 14 Feb 2012 In between 0 and 100, Gini coefficients are harder to interpret. A Gini coefficient of 50 represents 50 percent concentration in a country's income Other Publications in this Subject. Type. : Statistical Tables (Excel). Title. : Table E305 : Gini Coefficient by household size, 2006, 2011 and 2016. Latest Issue. 26 Apr 2017 Gini index for income inequality ranges from zero (absolute equality) to 100. 24. 30. 40. 50. Gini coefficient. In Graph 3.1, Europe is treated as the main reference of studying Chinese inequality, because Europeans' popular value pursuit, “born equal”
Notes on how to compute Gini Coefficient Suppose you are given data like this: The lowest 10% of earners make 2% of all wages The next 40% of earners make 18% of all wages The next 40% of earners make 30% of all wages The highest 10% of earners make 50% of all wages
Gini Index: The Gini index or Gini coefficient is a statistical measure of distribution developed by the Italian statistician Corrado Gini in 1912. It is often used as a gauge of economic That’s a pretty long chart, so I highlighted four countries to draw your attention to: Finland, Germany, France and the United States. As we can see, the income is more equally distributed in Finland (with a Gini index of 0.26) and less equally in the US (0.39). This minor change can have a major effect on the value of the Gini coefficient, e.g. in this case, Example 1 has a Gini coefficient of 0.67, and Example 2 has a Gini coefficient of 0.38. To avoid this pitfall, I recommend doing a secondary sorting like in Example 1 or simply to derive the Gini coefficient using the AUC method mentioned above. Relationship between AUC and Gini Coefficient Gini = 2*AUC - 1. You must be wondering how they are related. If you reverse the axis of chart shown in the above section named "Gini Coefficient", you would get similar to the chart below. Here Gini = B / (A + B). Area of A + B is 0.5 so Gini = B / 0.5 which simplifies to Gini = 2*B. China’s Gini Coefficient data was reported at 0.468 NA in Dec 2018.

The term “Gini coefficient” of a nation refers to the measurement of income distribution across the population of the nation. For instance, the Gini coefficient in India in the year 2000 can be compared with the coefficient of 2019. Gini coefficient can be used along with GDP numbers. If the Gini index is increasing along with GDP, then there may not be an improvement on the poverty front for the majority of the population. GINI index (World Bank estimate) World Bank, Development Research Group.
