Methods: A cross-sectional study analyzed the characteristics of infant mortality in parties and departments of Argentina and the social determinants of infant mortality in three levels of analysis. Results: The variables that showed a statistically significant association with infant mortality due to avoidable causes were: age of the deceased at the time of death, gestational age, place of occurrence of death, having attention or not, the level of instruction of the mother, employment status, overcrowding, and incomplete primary care. Conclusions: The factors that influence infant mortality exists as much at an individual level as they do at the family and population levels, and a large proportion of deaths are from preventable causes.
