The Gini Coefficient measures the differences in national income equality for countries around the world. A result of 0 represents perfect equality (where everyone has the same income) and 1 corresponds with perfect inequality (where one person has all the income, and everyone else has zero income.
The map charts these results simply by color coding: the closer a coutry’s equality is to 0, the cooler the color. If you live in an area with cool colors, the majority of the population enjoys a good Quality of Life (QofL), the best countries being green. Green countries enjoy a larger middle class, a more even distribution of wealth, and a greater Quality of Life for the majority of the population. In these countries, decent jobs provide people with a very decent Quality of Life. As countries move into purple, orange, and red colors, only a small percentage of people can afford what people in the green areas accept as normal, with the warmest-colored countries representing a very poor, even miserable Quality of Life for most people.
