Discussion
In a population GRR will be equal to NRR if
Answer: B
The gross reproduction rate equals the net reproduction rate when there is no mortality, because the NRR is the GRR reduced by the survival of women to each childbearing age. If every woman survives, the reduction vanishes and the two are equal.
A zero growth rate or replacement level means the NRR is 1 but the GRR is then higher than 1, and closure to migration has nothing to do with the relation between the two.
The NRR is calculated by multiplying the age specific fertility rates of women by the survival ratios, so with perfect survival the multiplier is one at every age, and the NRR cannot differ from the GRR.
