Methodology Statement: 2012 Diversity Index
This white paper details Esri's methodology of the derived index for population diversity in the United States.
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 our definition of the Diversity Index. Esri's diversity calculations accommodate up to seven race groups.
