In sociology and political studies, the term diversity is used to describe political entities (neighborhoods, student bodies, etc.) with members who have identifiable differences in their cultural backgrounds or lifestyles - wikipedia 
The term describes differences in racial or ethnic classifications, age, gender, religion, philosophy, physical abilities, socioeconomic background, sexual orientation, gender identity, intelligence, mental health, physical health, genetic attributes, behavior, attractiveness, or other identifying features.
In measuring human diversity, a diversity index measures the probability that any two residents, chosen at random, would be of different ethnicities. If all residents are of the same ethnic group it's zero. The diversity index does not take into account the willingness of individuals to cooperate with those of other ethnicities. If half are from one group and half from another it's .50.
