1
The Net Reproduction Rate (NRR) accounts for mortality by calculating the average number of daughters a woman would bear, adjusted for survival to each reproductive age. What key factor distinguishes it from the Gross Reproduction Rate (GRR)?
Question 1
2
In stable population theory, the intrinsic growth rate (r) is the eigenvalue solution to the Lotka equation, representing long-term exponential growth. Which condition defines a stationary population?
Question 2
3
Demographic momentum refers to continued population growth after fertility drops to replacement level due to a youthful age structure. What primarily drives this post-transition growth?

In the demographic transition model, Stage 3 features declining fertility amid stable mortality. Which factor is most associated with this fertility decline in developing regions?
Question 6
7
