Figure 1: Illustration of Gini Coefficient and Its Calculation. Suppose we examine the income of every individual of a country and arrange the individuals in order of increasing income. If we plot the percentage of national income versus the population percentage (Lorenz curve), we will get a curve like that shown
GINI Coefficient: The National Income Equality Score. According to this version, we have Sweden at 23. Denmark: 24. Slovenia: 24. Iceland: 25...United States: 45...and last, and actually quite least, Namibia at 71. Funny thing, we tend to enjoy our communities a lot more when our neighbors have about the same amount of wealth as we do.
