Income Inequality in Los Angeles County and Adjacent Counties
About the chart
Los Angeles County has the highest level of income inequality, measured by the Gini index, in comparison to its adjacent counties. Income inequality is increasing in all represented regions. We expect the upward trend to continue in the absence of more equitable and more efficacious public policy.
What is the Gini index?
The Gini index (also known as the Gini ratio and coefficient) is a summary of income inequality income (U.S. Census Bureau, January 2016). The Gini index is a number from 0 to 1 that represents the income inequality level in a region. A Gini index of 0 expresses perfect equality where everyone receives an equal share. A Gini index of 1 expresses perfect inequality where only one person receives all the income and the rest receives none.
Why do we care?
Gini index is negatively correlated with improved social indicators, economic growth, and political bipartisanship. Social indicators refer to measures that describe human well-being, covering a full range of issues, including educational attainment, unemployment, crimes, teenage pregnancy, and life expectancy. Therefore, low Gini index benefits our society, economy, and democracy. For more details on how inequality affects our society, economy, and democracy, please read the OECD’s report titled “In It Together: Why Less Inequality Benefits All” (May 2015).
