Question

Quizplus · Accepted Answer

The net reproductive rate (NRR) is the sum of the product of survival rate and age-specific fertility rate (lxbx) over all fertile ages. Therefore, the best choice is option A, which includes both survival rate (lx) and age-specific fertility rate (bx). Option B only includes the age-specific fertility rate (bx), option C only includes the survival rate (lx), and option D only includes age (x), which is not relevant for calculating the NRR.
