The sociology of American Indians incorporates perspectives from across the social sciences. Recently, sociologists have taken a greater interest in American Indians, perhaps because American Indians have become increasingly visible in the diverse ethnic mosaic of American society. This review focuses on the position of American Indians in the US socioeconomic hierarchy: their numbers, where they live, and their social and economic well-being. The collapse and revitalization of the Indian population has been a central issue within American Indian demography. The recent growth in the population has been accompanied by increasing urbanization. These developments have significant implications for the socioeconomic well-being of American Indians in contemporary society.
