Applied Anthropology refers to the application of the method and theory of anthropology to the analysis and solution of practical problems. It is a, "complex of related, research-based, instrumental methods which produce change or stability in specific cultural systems through the provision of data, initiation of direct action, and/or the formulation of policy". More simply, applied anthropology is the practical side of anthropological research; it includes researcher involvement and activism within the participating community. It is closely related to Development anthropology (distinct from the more critical Anthropology of development).
