The Diversity Index (DI) is a scale of 0 to 100 that represents the likelihood that two persons, chosen at random from the same area, belong to different races or ethnic groups. If an area’s entire population belongs to one race and one ethnic group, then the 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.
