Sample itemA population has a gross reproduction rate of 1.8 and a net reproduction rate of 1.6. Why is the net rate lower?
Original practice item, not a recalled exam question. Nothing here is recorded.

B. It allows for deaths of girls before the end of the reproductive years
The net reproduction rate adjusts the gross reproduction rate for mortality of females up to the end of reproductive ages, so it is lower. Both count female births only.

B. It allows for deaths of girls before the end of the reproductive years (correct)
Correct. NRR accounts for female mortality.
C. It includes migration
