Below is a picture of how to use excel to calculate the necessary values in order to get the Gini Coeffecient. Once you get the total value, the Gini Coefficient is calculated as $1-\text{total value}$, which in this case is $1-0.733=0.267$ rounded to the nearest thousandth. Hello all, does anyone have any ideas on how the formula for the GINI coefficient could be expressed in Excel ΣiΣj(yi-yj) In the formula, y refers to income and both i and j refer to households. Thus for instance if there were two households then to get ΣiΣj(yi-yj) first set i equal to one then do the single sum across the js. The Gini coefficient is the area between the Lorenz curve and the diagonal divided by ½. The area is divided by ½ because that’s the area of the 1×1 triangle that is all the area below the diagonal line. The calculation is simple: Note that you are multiplying by two which is equivalent to dividing by ½. Hi, I'm trying to write a custom function to calculate gini coefficients. I've been able to use this function when inputted manually: (Where X is a Creating a Custom Excel Function to Calculate Gini Coefficients - ExcelBanter Once a Lorenz curve is constructed, calculating the Gini coefficient is pretty straightforward. The Gini coefficient is equal to A/(A+B), where A and B are as labeled in the diagram above. (Sometimes the Gini coefficient is represented as a percentage or an index, in which case it would be equal to (A/(A+B))x100%.) There are many ways to calculate the Gini coefficient. The question is really one of how much detail you need. The amount of detail is how much grouping you are willing to accept in your population groupings. You could calculate an absolute inequality coefficient by measuring everyone's income and its deviation from the mean. You'll get a lower Gini coefficient with a sample such as v = 10 + np.random.rand(500). Those values are all close to 10.5; the relative variation is lower than the sample v = np.random.rand(500). In fact, the expected value of the Gini coefficient for the sample base + np.random.rand(n) is 1/(6*base + 3).

The Lorenz Curve. In order to calculate the Gini coefficient, it's important to first understand the Lorenz curve, which is a graphical representation of income inequality in a society. A hypothetical Lorenz curve is shown in the above diagram.

GINI Coefficient Formula. In the formula, y refers to income and both i and j refer to households. Thus for instance if there were two households then to get ΣiΣj(yi-yj) first set i equal to one then do the single sum across the js. Then set i = 2 and do the single sum across the js. Sum the two sums, and you have it. of the Gini is to divide by the area of the triangle which is ½. So: Area of Trapezoid / (1/2) = 2*Height*(Base at top + Base at bottom). In our calculation, the fraction of wealth is the height of the trapezoid, and the bases are “fraction of population that is richer than this group” and “fraction of population that is The Lorenz Curve. In order to calculate the Gini coefficient, it's important to first understand the Lorenz curve, which is a graphical representation of income inequality in a society. A hypothetical Lorenz curve is shown in the above diagram. The Gini index is commonly used to measure wealth or income inequality in a population. A Gini index for income of 0 means that all the members of the population have the same income, an index of 0 means that one member of the population gets all the income and everyone else has no income.

21 May 2011 A Bias Correction factor of n/(n-1) is usually applied. Calculating Gini Coefficients using Excel. The Gini Formula can be written as an Excel array

The formula for the Gini coefficient can be derived by using the following steps: Step 1: Firstly, collect the income information for the entire population and arrange Step 2: Next, group the population into different segments based on the level of income. Step 3: Next, calculate the Example of Gini Coefficient Formula (with Excel Template) Step 1: Write the ‘Fraction of Income’ and ‘Fraction of Population’ data in tabular format in Excel. Step 2: Fill ‘% of Population that is richer’ column by adding all terms in ‘Fraction of Population’ below that row. For instance, in the The Gini index is the equal to twice the area between the Equality and Lorenz curves. Note that the area under the Equality curve is 0.5 and the area under the Lorenz curve can be approximated by adding the areas of trapezoids as described in ROC Data Analysis Tool.

The Gini index is commonly used to measure wealth or income inequality in a population. A Gini index for income of 0 means that all the members of the population have the same income, an index of 0 means that one member of the population gets all the income and everyone else has no income.

Learn how the Gini coefficient can be used to interpret income inequality in this video. The x-as is then males and the y-as female for example. Comment. The Gini coefficient was developed by the Italian Statistician Corrado Gini (Gini, 1912) as a summary measure of income inequality in society. It is usually The formula for the Gini coefficient can be derived by using the following steps: Step 1: Firstly, collect the income information for the entire population and arrange Step 2: Next, group the population into different segments based on the level of income. Step 3: Next, calculate the Example of Gini Coefficient Formula (with Excel Template) Step 1: Write the ‘Fraction of Income’ and ‘Fraction of Population’ data in tabular format in Excel. Step 2: Fill ‘% of Population that is richer’ column by adding all terms in ‘Fraction of Population’ below that row. For instance, in the The Gini index is the equal to twice the area between the Equality and Lorenz curves. Note that the area under the Equality curve is 0.5 and the area under the Lorenz curve can be approximated by adding the areas of trapezoids as described in ROC Data Analysis Tool. Calculating Gini Coefficients using Excel. The Gini Formula can be written as an Excel array formula (Array1, credited to Harlan Grove) (ignoring the Bias correction Factor): {=AVERAGE(ABS(DataPoints-TRANSPOSE(Datapoints)))/AVERAGE(Datapoints)/2} The Gini Coefficient of Inequality (aka the Gini Index) is a statistic that measures the inequality within a population based on some non-negative measurement. For a finite sample or population of size n with measurements x 1 , x 2 , …, x n in ascending order, the Gini index can be defined in any one of the following equivalent ways:

Using the above formula we can calculate the Gini index for the split. Gini(X1=7) = 0 + 5/61/6 + 0 + 1/65/6 = 5/12. We can similarly evaluate the Gini index for each split candidate with the values of X1 and X2 and choose the one with the lowest Gini index. In this case, if we look at the graph then we see that we can draw a vertical line at X1=8.
