Designed for those seeking data on Native Americans, this paper presents U.S. census data sources and the developments which have taken place in data collection procedures and definitions between 1860 and 1970. Specifically, this paper presents: (1) development of race concept and definitions (emphasis on American Indian, Aleut and Eskimo, and Hawaiian definitions); (2) data products (identification of numerous reports derived from census data which are relative to American Indians, Aleuts, Eskimos, and Hawaiians); (3) geographic and demographic perspectives (population concentrations and trends, rural to urban migration, rural-urban differences, tribal size, educational and income differences, etc.); (4) a sampling of current literature on Native Americans (an annotated list of 23 titles which are representative of current literature on Native Americans and suggest a geographic perspective). Among the more recent data products cited are: (1) the Data Access Descriptions Report Number 40, Data on Selected Racial Groups; (2) a separate Volume II Subject Report of the 1970 Census, American Indians PC (2)-1F; (3) the 1970 Census Volume II Subject Report, Housing of Selected Racial Groups, HC (7)-9; (4) a magazine pamphlet, "We, the First Americans" (1973).
