Augmenting published and unpublished sources with information culled from personalized questionnaires sent to key scholars and practitioners, Sylvia Wargon describes and interprets the development of the field. She provides important background information about the origins and history of demography in Europe and Canada from the seventeenth to the nineteenth century, and explains the gradual development and institutionalization of demography in the French- and English-speaking regions of Canada. Important milestones are discussed in the context of their social environment. Based on French- and English-language sources, Demography in Canada in the Twentieth Century is the first and only comprehensive treatment of the subject to date.
