In a ceain population, there were 4050 bihs in the last one year. There were 50 still bihs. 50 infants died within 7 days whereas 150 died within the first 28 days. What is the Neonatal moality rate?

50 Number of death of children under = x 1000 In the question; Total no. of deaths under 28 days = no. of deaths within 7 days + no. of deaths within the first 28 days. Total no. of live bihs = Total bihs - still bih. So, NMR = x1000 = x1000 = 50per 1000live bihs
