Three general methods for obtaining measures of diversity within a population and dissimilarity between populations are discussed. One is based on an intrinsic notion of dissimilarity between individuals and others make use of the concepts of entropy and discrimination. A criterion is developed for choosing a measure of diversity in a given class of measures. The Gini-Simpson index of diversity is derived as the solution to a functional equation. Author
