The Gini Coefficient is based on the Lorenz Curve and measures the degree of income or wealth inequality in an economy. The coefficient is bound between zero and one. This means that the coefficient can take on values between zero and one. A Gini Coefficient of one states complete inequality. That is, one single person receives all the income or holds all the wealth of the economy, while all others receive or own nothing. A Gini Coefficient of zero implies perfect equality. That is, all individuals obtain the same income. See the discussion of the Lorenz Curve for a clear illustration of the concept. Continue reading The Gini Coefficient

In the case that everyone has approximately the same wealth, we have a very equal society. While in a case where few own the majority of wealth, we have high inequality. The following figure depicts the Lorenz curve for three economies with varying degrees of inequality.
