Name | Gini Coefficient |
Summary | Gini Coefficient (measure of income inequality) by U.S., state, counties, cities, zip codes |
Additional Background | The Gini Coefficient (or Index) measures income inequality for households. The coefficient ranges from 0 (perfect equality) to 1 (perfect inequality).
Zip codes reported reflect Zip Code Tabulation Areas (ZCTA), which are different from ZIP Codes used by the U.S. Postal Service. Some sources for this database report zip code rather than ZCTA; values for these variables are reported only when zip code and ZCTA values are the same. See here for more information on ZCTAs.
