Question

What is net production rate?
A ) Number of death of children below one year of age per 1000 live birth
B ) birth rate minus death rate
C ) average age to which a person at the time of his birth is expected to live
D ) the average number of daughters that would be born to a female through her lifetime.

Answer 1

Hint:The net reproduction rate in the presence which is known as NRR, depicts how many daughters will be born.This rate is quite similar to the gross rate but takes in account that some of the females will die before completing their childbearing years.

Complete answer:
 Number of death of children below one year of age per 1000 live birth:
 death of young children under the age of 1 is said as infant mortality rate.This death factor is measured by the infant (IMR). The under 5 mortality rate, referred to as the child mortality rate, is also an important statistic.

birth rate minus death rate: it is the Number of males per 100 females in population. Also we can say ,Crude birth rate minus the crude death rate. It Represents the portion of population growth or the decline.

 average age to which a person at the time of his birth is expected to live: Life expectancy is a type of statistical measure of the average time an organism can be expected to live.it is based on the factors like year of its birth, current age, and other factors which include gender.

 the average number of daughters that would be born to a female through her lifetime: The net reproduction rate in the presence of migration, indicates the no.of daughters would be born.on an average, the female babies who pass through life , and are subjected at each age so that rates of fertility, mortality, migration can observed.

Hence, the correct answer is option (D).

Note:In the population demography and ecology and, the net reproduction rate, referred as Ro. The R0 is specifically important where sex ratios at time of birth are affected by the use of reproductive technologies.
