Allegan County 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 Allegan County 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 uses ACS 5-year estimates for Allegan County Gini Index data, rather than single-year periods. The 5-year estimates provide greater geographical granularity and accuracy, with a less granular time period.
