The Diversity Index estimates the likelihood that two persons chosen at random from the same area belong to different race or ethnic groups, based on five groups: Hispanic/Latino, Non-Hispanic White, Non-Hispanic Black, Non-Hispanic Asian, and Non-Hispanic Other/Multiracial. A value of 0 indicates the population belongs entirely to one group. Higher values indicate a more evenly mixed population. Calculated from U.S. Census Bureau ACS 5-year estimates (table B03002).
