The incidence of the migratory factor in the demographic bond at provincial level. Argentina (1947-2010)
Main Article Content
Abstract
The hypothesis that guides this article is that the absence of the migratory component in the definitions of the demographic bond turns out to be one of the main limitations for the knowledge of the behavior of the same one. At the moment of divergent results are evident in the demographic dependence charges provincial, the theory of the demographic transition is far from adapting itself to the above mentioned empirical evidences. This theory is restricted to individual analyses of the demographic dynamics by means of regularities established on the changes in the birth rate and mortality. Based only on the vegetative growth, one of its explanatory insufficiencies is the omission of the role of the migrations. The target is to analyze the impact of the migratory factor on the demographic bond in the provinces of Argentina during the period 1947-2010. Bearing in mind the differences in population participation migrants in interprovincial terms, and of its changeability throughout seven considered required years, which deep differentiations generate in the composition of the big groups of ages and interferences in the period corresponding to the demographic bond. The study centers principally in the provinces with migrants’ major and less presences on its demographic structures.
