The Gini index and Lorenz curve are used to measure the distribution of income among the inhabitants of any given region. The Lorenz curve is represented as y=L(x) on the interval [0,1] by plotting the point (a/100, b/100) on the curve if the bottom a% of households receive at most b% of the total income. Whereas the Gini index (sometimes called the Gini coefficient or the coefficient of inequality) is the area between the Lorenz curve and the line y=x. We estimate the Gini index for the income inequality distribution of the residents of city of Jacksonville, Alabama using a quadratic and Lagrange polynomial model for the Lorenz function.
