Now,
ΣASFR × 5
TFR =
1000
1576 × 5
=
1000
= 7. 88 per woman

∴ TFR of women in mountain and hilly region were 6.80 per woman and 7.88 per
woman respectively.

Activity: 2

Calculate TFR of women on the basis of following table:
Age Group Age Specific Fertility Rate (ASFR) per 1000 women
(15 – 19) 80

(20 – 24) 185
(25 – 29) 130
(30 – 34) 70
(35 – 39) 35
(40 – 44) 15
(45 – 49) 5
Total 520

Answer: 2. 6 per woman

Measurement of Mortality
According to WHO, death can be defined as, “The permanent disappearance of all the
evidences of life.” Death is natural factor of population change. Everyone in the earth
whoever has taken birth has to die sooner or later.

Mortality can be measured by four different ways which are given below:
a. Crude Death Rate (CDR)
b. Age Specific Death Rate (ASDR)
c. Infant Mortality Rate (IMR)

d. Maternal Mortality Rate (MMR)

a. Crude Death Rate (CDR)
The total deaths among 1000 mid year population in a place in a year is called as crude
death rate.
