The Alyawara Ethnographic Data Base contains approximately 440,000 items of raw, numerically coded ethnographic data from the Alyawara tribe of Central Australia. The data include vital statistics, genealogies, kinship term applications, censuses, maps, group compositional data, behavior stream observations, and meteorological records. All of them have been placed on magnetic tape to facilitate computer-assisted analysis. The data base, and a manual that explains its contents, structure, and operation may be purchased for use in teaching or research. This article is a brief in troduction to the data base.
