Segregation and diversity measures in population distribution.

"The purposes of the present paper are to show the relationship between measures of population diversity and measures of segregation, to describe the salient properties of these indexes, and to demonstrate the empirical interrelationships among them." Some measures not frequently used in population studies are considered, and empirical illustrations are given of the significance of using one measure rather than another. In particular, the author stresses proportional reduction of error interpretations for an index and considers its ability to handle more than two groups. The primary geographic focus is on the United States. The "introductory section of the paper treats conceptual issues in more detail. The second section reviews selected measures and recent critical viewpoints, while the third section tests their empirical performance. The conclusion makes some recommendations about the selection of an index. A detailed bibliography follows." excerpt
