Income inequity, ZCTA. 2008-2012 ACS 5-year ACS

Income inequity is measured using the index of concentration at the extremes (ICE). ICE, developed by Douglas Massey in 2001, is a measure of social polarization within a particular geographic unit. It shows whether people or households in a geographic unit are concentrated in privileged or deprived extremes. Our privileged group is the number of households with a householder identifying as White alone, not Hispanic or Latino, with an income equal to or greater than \$100,000. Our deprived group is the number of households with a householder identifying as a different race/ethnic group (e.g., Black alone, Asian alone, Hispanic or Latino), with an income equal to or less than \$25,000. We have computed the income inequity measure for the following groups: White alone, not Hispanic or Latino:Black alone White alone, not Hispanic or Latino:Asian alone* White alone, not Hispanic or Latino:Hispanic or Latino
