[The beginning of the fertility transition in Mexico. The offspring of women born in the first half of the twentieth century].

Abstract

"The analysis of probable growth rates among families, based on census figures, proved that fertility rates in Mexico began to fall earlier and less selectively than suggested by previous studies. The first changes in reproductive patterns occurred prior to official family planning programs. A state-by-state probability analysis discovered the existence of three groups of states corresponding to the different stages of changing fertility rates." (SUMMARY IN ENG)
