^bThe Gini coefficient of income inequality represents the inequitable distribution of income in a community by household, and can range from 0 to 1. The County Health Rankings multiplies the Gini coefficient by 100, so that the values can range from 0 to 100. A value of 100 indicates that all income in a county is concentrated in one household, while a coefficient of 0 indicates a completely equal distribution of income among households.
