denotes very good socio-economic and health condition in the country. Generally, the
developed nations have very low IMR but poor and developing nations have high IMR.

Worked out example: 7
In a village in 2010 A.D., there was birth of 986 children. If the infant mortality rate of that
village was calculated as 11.15 per 1000, what would be number of infants died?

Solution:
Given,

In a village in 2010 A.D.,
Total live births = 986
Infant mortality rate (IMR) = 11.15 per 1000

No. of infants died = ?
We know,
Total deaths of infants in a place in a year
IMR = × 1000
Total live births in a place in a year

Total deaths of infants
or, 11.15 = × 1000
986

11.15 × 986
or, Total deaths of infants =
1000

= 10.99 ≈ 11
∴ There was death of 11 infants in that village in 2010 A.D.

d. Maternal Mortality Rate (MMR)
According to WHO, maternal death is defined as, “The death of a woman while pregnant
or within 42 days of termination of pregnancy, irrespective of the duration and site of the
pregnancy, from any cause related to or aggravated by the pregnancy or its management
but not from accidental or incidental cause.”
Maternal mortality rate is defined as total deaths of mothers in 100000 live births in a
place in a year especially due to problems related to reproduction and pregnancy.
Mathematically,
Total deaths of mothers in a place in a year
MMR = × 100000
Total live births in the place in the same year

It is also expressed per 100000.
