Throughout this text, the author applies an anthropological concept of social and cultural pluralism to the Mackenzie River Delta, utilizing data collected between 1965 and 1967. The plural concept is used to describe and analyze patterns of relationships between northern Native people and "Outsiders", or Euro-Canadians. In this study, the relationship between these ethnic categories is shown to be marked by a vertical pattern of stratification. The conjunction of ethnic, class, and culture boundaries, which constitutes the plural relationship is explored in various dimensions such as political, occupational, educational, economic. An attempt is also made to outline the conditions of social well being characterizing the Native way of life. An outline of the cultural, political and economic parameters of optimal conditions for improving the well being of Native people by the facilitation of a reduction in their pluralistic relationship with outsiders is examined. Charts illustrating the distribution by sex and age of selected populations in the Mackenzie River Delta; an occupational survey; income by month from employment; fur sales by native people; and a calculation of cash-equivalent values of wild foods are all included. Questionnaires administered to students and teachers, maps and a bibliography are also provided. This work is primarily a study in ethnic relations and applied Anthropology.
