Abstract

Demographic transition: new premises, old challenges. The text discusses formulations about the demographic transition, contrasting the proposals of the seventies with recent ones. The globalizing and critical focus prevalent in the first period gave place to more segmented formulations, with an ample empirical base, but of small explanatory range. The practice of specific demographies was reinforced, with its peculiar evolutions, in the study of each component of the populational dynamics. Little progress was also obtained in the reformulation of the relations between population and economic and social development in the present context. Detailed historical reconstructions seem to constitute a promising interpretative vein in the recuperation of demographic transition as a theory of population.
