Los Años de la Crisis: An examination of change in differential infant mortality risk within Mexico

The main aim of the present analysis is to test the possibility that the period of economic hardship characterizing Mexico over the decade 1986–1996 has negatively influenced infant health outcomes. Data on births from two installments of the Encuesta Nacional de la Dinámica Demográfica, a nationally representative demographic survey, are used to determine whether a reduction in mortality differentials has paralleled the overall drop in the national infant mortality rate. The findings indicate that the decrease observed in the overall infant mortality rate has been matched by decreases in several disparities at the same time that it has been marred by increases in others. The data support the possibility that where you live has become an increasingly salient factor in determining the odds of infant mortality. High parity, low education and unemployment status have also become more salient factors in predicting post neonatal infant mortality risk in the more recent period as compared to the earlier period. As Mexicoʹs infant mortality rate begins to stabilize in the near future, this research highlights the need to re-focus our research efforts on the causes and consequences of differential mortality trends.
