Examining Inequality in Pima County
Recently, social scientists have examined the relationship between economic inequality and a large number of indicators of well-being. The general conclusion is that greater inequality is associated with lower levels of well-being. The U.S. Census Bureau provides information about household income inequality at several geographic levels, from the nation to the neighborhood (census tract). The primary indicator is the Gini Coefficient that ranges theoretically from zero (perfect equality) to 1.0 (perfect inequality). The Bureau currently reports estimates on the basis of large samples gathered as part of the American Community Survey (ACS). This 5 year series (2005-2009) enables the presentation of highly precise measures. The Gini coefficients for the U.S as a whole ranged from .464 to .469 during this period.
