Countries by Gini Coefficient
Figure 4.13 shows a thematic map that uses Gini coefficients, a tool Corrado Gini, an Italian statistician and sociologist, created to indicate global income inequality. While issues remain with regard to interpreting this data, Gini coefficients do provide a general overview of income equality.
A Gini coefficient of zero means everyone has the same income. A higher Gini coefficient indicates more unequal incomes. For example, the southern part of Africa has high coefficients, but they are low in Norway, Sweden, and Finland, where income inequality is low. In North America, income inequality is higher in the United States than it is in Canada.
