Abstract : Kinship under the Microscope : A New Software for the Analysis of Matrimonial Networks. — Marriage choices can not be treated as isolated phenomena. They draw their meaning from how they are distributed and combined so as to form complex patterns whose study requires the use of computerized tools. While computers have been used in the study of kinship for over forty years, an instrument capable of making a complete matrimonial census of a kinship network has been lacking. The software Puck (Program for the Use and Computation of Kinship Data) fills this gap. This article presents the main applications of this software, and discusses the theoretical issues and methodological choices that went into its development.
