OBJECTIVE: to investigate associations between infant survival and maternal, pregnancy, parturition and newborn characteristics, in the birth cohort of 2005, in the municipality of Rio de Janeiro, state of Rio de Janeiro, Brazil. METHODS: a retrospective cohort study, carried out using data from Live Birth Information System (Sinasc) and Mortality Information System (SIM); probability of infant survival was estimated using tactuarial life table and Kaplan-Meier methods. RESULTS: the probability of infant survival was estimated in 0.9861; highest probabilities of death were found among babies born to mothers aged under 20years (0.0148), by vaginal delivery (0.0146), male (0.0154), weighing under 2,500g (0.0861) and premature (0.0992); about 65.0% of these deaths could be avoided improving perinatal care health services. CONCLUSION: the use of National information systems data is an important tool to define maternal and child policies.
