US Gini Coefficient Map



Pure green shows a Gini coefficient of 0.40.
Pure yellow shows a Gini coefficient of 0.45.
Pure red shows a Gini coefficient of 0.50.

The higher the coefficient, the greater the income inequality.

District of Columbia comes in at a whopping 0.537 (off my scale, not shown).

This is a little nit-picky because all the GINI scores are so close to .5. However, your statement, "The higher the coefficient, the greater the income inequality." is incorrect.

The correct statement is:
The higher the coefficient, the greater the income EQUALITY.

Anonymous,

I said it correctly. You have it backward.

Gini coefficient

The Gini coefficient is a measure of the inequality of a distribution, a value of 0 expressing perfect equality where everyone has equal shares of income and a value of 1 expresses maximal inequality where only one person has all the income.
