![]() B is the area below the line of perfect equality.A is the area between the Lorenz curve and the line of perfect equality.The formula to calculate the Gini coefficient is: ![]() ![]() To calculate the Gini coefficient, we compare the area between the Lorenz curve and the line of perfect equality (the 45-degree line) to the total area below the line of perfect equality. We calculate the cumulative shares as follows:Ĭumulative Share of Population (equally distributed):Ġ.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0 The Lorenz curve represents the cumulative share of income plotted against the cumulative share of the population. Let's say the income distribution among the 10 individuals is as follows (in arbitrary units): Gini Coefficient Calculator exampleĬertainly! Let's consider an example of calculating the Gini coefficient for a fictional income distribution among 10 individuals.įirst, we need to arrange the incomes in ascending order. Gini coefficient calculators can be found online or implemented in statistical software packages like R, Python, or Excel, often as part of their built-in functions for inequality analysis. Other measures and factors should be considered when examining economic disparities and social issues related to income or wealth distribution. It's important to note that the Gini coefficient is just one measure of income or wealth inequality, and it has its limitations. The Gini coefficient ranges from 0 to 1, where 0 represents perfect equality (all individuals have an equal share of income or wealth) and 1 represents maximum inequality (one individual has all the income or wealth).ĭisplaying the Result: The calculator provides the calculated Gini coefficient as the output, indicating the level of income or wealth inequality in the given population. Gini Coefficient Calculation: The Gini coefficient is calculated by comparing the area between the Lorenz curve and the line of perfect equality (also known as the 45-degree line) to the total triangular area under the line of perfect equality. The Lorenz curve represents the cumulative share of total income or wealth received by the corresponding cumulative percentage of individuals or households. Lorenz Curve Plotting: Based on the cumulative percentages, the calculator plots the Lorenz curve on a graph. This cumulative percentage helps determine the Lorenz curve. Sorting: The calculator will sort the income or wealth values in ascending order, from lowest to highest.Ĭumulative Percentage Calculation: The calculator then calculates the cumulative percentage of total income or wealth that each income or wealth bracket represents. This can be done by inputting the individual incomes or household wealth values, or by specifying the frequency or percentage of individuals or households falling into different income or wealth brackets. Here's how a Gini coefficient calculator typically works:ĭata Input: You would need to provide the calculator with the distribution of income or wealth among individuals or households. The Gini coefficient is a widely used statistical measure in the field of economics and social sciences. what is Gini Coefficient CalculatorĪ Gini coefficient calculator is a tool that calculates the Gini coefficient, which is a measure of income inequality or wealth distribution within a population. Sigma Level: Organizations determine the sigma levels of given processes (one sigma, six sigma, etc.) as a means of comparing the performance of those processes throughout the entire organization as distinct elements. To calculate process yield, we use the following formula: Yield: The percentage of a process that is free of defects. For instance, if we sampled 800 units and found 50 defects with 5 opportunities per unit and multiplied this figure by 1 million, the DPMO would be as follows: For instance, if we sampled 800 units and found 50 defects with 5 opportunities per unit, the DPO would be as follows:ĭefects Per Million Opportunities (DPMO): The total defects in a sample divided by the total defect chances multiplied by 1 million. For instance, if we sampled 800 units and detected 50 defects, the DPU would be as follows:ĭefects per Opportunity (DPO): The total defects within a sample divided by the total defect chances. Defects per Unit (DPU): The total defects within a sample divided by the number of units that were sampled.
