[Adjustment of an expologistic function to the evolution of Mexico's total population, 1930-1945].

The author makes the case that none of the mathematical models currently in use for estimating population dynamics can be suitably applied to Mexico's natural growth "due to the fact that the assumptions underlying [their] mathematical representations do not correspond to the observed dynamics of the components of natural growth. The purpose of this article is to adjust a mathematical function to the evolution of Mexico's total population between 1930 and 1985, adequately reproducing the evolution of natality and mortality observed in that period."
