Maine Gini Index of Income Inequality
The Gini Index, or Gini coefficient, is a statistical measure of distribution that is often used to track economic inequality. It measures how wealth is distributed in a given population. The output is a value between 0 and 1. In Maine and throughout the country, Gini Index is a major focus of the American Community Survey (ACS), conducted each year by the U.S. Census Bureau.
Higher values mean greater inequality. A Gini value of 0 means a perfectly equal society, where everyone's income is the same. A value of 1, on the other hand, represents perfect inequality—a society in which only one person or group has all the wealth. This report explores how Maine’s Gini Index is changing—and how the data compares to the United States as a whole.
