Statement (A): NRR = GRR, all the new born girls survive till the end of the reproductive period. - GRR (Gross Reproduction Rate) The average number of daughters that would be born to a woman if she lived through her entire childbearing years and experienced the age-specific fertility rates of a given year. It does not account for mortality. - NRR (Net Reproduction Rate) The average number of daughters that would be born to a woman if she lived through her entire childbearing years and experienced the age-specific fertility rates and age- specific mortality rates of a given year. It accounts for mortality.If NRR = GRR, it implies that the total fertility (measured by GRR) is equal to the net replacement fertility (measured by NRR). This can only happen if there are no deaths among women during their reproductive period. In other words, all newborn girls survive to complete their reproductive potential, making the mortality component irrelevant.Statement (B): NRR = 1, then for a given fertility and female mortality, a group of new born girls will exactly replace itself in the next generation. - When NRR = 1, it means that, on average, each cohort of newborn girls will be replaced by exactly one daughter who survives to reproductive age and has daughters. This signifies a stable population size in terms of females. The population is neither growing nor declining in the long run, assuming fertility and mortality rates remain constant.
