This project aims to investigate the importance of adequate health care for pregnant women and its effects on maternal and child mortality, considering the role of distances traveled for pregnant women to access health facilities and, consequently, for the care they receive. The results will be useful to identify the gaps in maternal health care and to drive decisions on resources allocation and prioritized actions. The information generated will compose a database containing, in addition to distances, several measures of maternal and child health outcomes that will enable large-scale research across the country.
