摘要：The border zone is generally characterized by a relatively advanced demographic transition which would be determined by factors at the national and international, that have been felt unevenly across the bordering territory in the United States, generating socioeconomic and cultural heterogeneities within “Region” reflected in the unequal demonstration of this sociodemographic conditions, which in the case of fertility presents changes in their levels and timing of it, concentrating births in younger women. Variations in fertility observed in the northern Mexico border, have peculiarities that need to be evidenced by its relationship to social, family and individual issues. This is the case of fertility of younger women, which deviate from the general trend to decrease of that variable, which may have no significance beyond the population, but because it is mostly non–planned by couples.
