The Diversity Index from Esri represents the likelihood that two persons, chosen at random from the same area, belong to different race or ethnic groups. Ethnic diversity, as well as racial diversity, is included in this definition of the Diversity Index. Esri’s diversity calculations accommodate up to seven race groups: six single-race groups (White, Black, American Indian, Asian, Pacific Islander, Some Other Race) and one multiple-race group (two or more races). Each race group is divided into two ethnic origins, Hispanic and non-Hispanic. If an area is ethnically diverse, then diversity is compounded. If an area’s entire population belongs to one race group and one ethnic group, then an area has zero diversity. An area’s diversity index increases to 100 when the population is evenly divided into two or more race/ethnic groups.
