Infant mortality rate comprises of two parts, viz. Neo-natal mortality rate and Post neo-natal mortality rate.
The neo-natal mortality rate also comprises of two parts viz. Early neo-natal mortality rate and late neo-natal mortality rate.
These are defined as:
|
Neo-natal mortality
rate (NMR)
| Number of infant deaths of < than 29 days during the year
--------------------------------------------------------------------------------- x 1000
Number of live births during the year
|
Early neo-natal
mortality rate
| Number of infant deaths of < than 7 days during the year
---------------------------------------------------------------------- x 1000
Number of live births during the year
|
Late neo-natal
mortality rate
| Number of infant deaths of 7 days to < than 29 days during the year
--------------------------------------------------------------------------------------------- x 1000
Number of live births during the year
|
Post neo-natal
mortality rate(PNMR)
| Number of infant deaths of 29 days to < than one year during the year
------------------------------------------------------------------------ x 1000
Number of live births during the year
|
Peri-natal mortality
Rate (PMR)
| Number of still births and infant deaths of < than 7 days during the year
----------------------------------------------------------------------------------------------- x 1000
Number of live births and still births during the year
|
Still birth rate
| Number of still births during the year
----------------------------------------------------------------------- x 1000
Number of live births and still births during the year |
