In a certain population, there were 4050 births in the last one year. There were 50 still births. 50 infants died within 7 days where as 150 died within 28 days. What is the Neonatal mortality rate?

Total number of births in one year = 4050 No. of still births in that year = 50 Hence, total number of live births in that year would be 4050 – 50 4000 Total number of infants dying in the first 7 days = 50 Total number of infants dying in the next 21 days = 150 Hence, total number of infants dying in the first 28 days of birth = 50 + 150 Now, Neonatal mortality rate = 50
