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." (SUMMARY IN ENG)
作者认为，目前用于估计人口动态的数学模型中，没有一个能够适用于墨西哥的自然增长情况，“因为其数学表示所依据的假设与自然增长各组成部分观察到的动态不相符。本文的目的是调整一个数学函数，使其与1930年至1985年墨西哥总人口的演变情况相适应，从而充分再现该时期观察到的出生率和死亡率的演变情况。” （英文摘要）
