Work out neonatal mortality rate instantly with clear inputs, formula shown and shareable results.
Divides deaths in the first 28 days by live births and splits infant mortality into neonatal and post-neonatal components.
Neonatal mortality
NMR = deaths in the first 28 days / live births x 1000; post-neonatal rate = (infant deaths - neonatal deaths) / live births x 1000
Neonatal deaths are dominated by prematurity, intrapartum events and infection, needing different interventions from later infant deaths.
Typically 60 to 75%, and the share rises as overall child mortality falls.
