Deaths occurring from 28 days of life to under one year are called –

[a] Post-neonatal deaths
[b] Infant mortality rate
[c] Neonatal mortality rate
[d] Perinatal mortality rate

✅ Correct Answer:
[a] Post-neonatal deaths

Explanation:

Human infant mortality is classified based on age at death to help public health programs understand and address causes of death more accurately.

Term	Definition
Neonatal Deaths	Deaths of a baby within the first 28 days of life.
Post-Neonatal Deaths	Deaths of a baby from 28 days to less than 1 year of age. ✅
Infant Mortality Rate (IMR)	The total number of deaths of infants under one year of age per 1,000 live births in a year.
Perinatal Mortality Rate	Includes late fetal deaths (stillbirths after 28 weeks) and early neonatal deaths (within the first 7 days).

Summary:

🔺If a baby dies after 28 days but before turning 1 year old, it's classified as a post-neonatal death.
🔺This classification helps track health system performance and causes like infections, malnutrition, or SIDS (sudden infant death syndrome).
