Question #1272
If Net Reproduction Rate (NRR) = 1.0, the population will eventually stabilize assuming:
A. Increasing mortality
B. Rapid urbanization
C. High emigration
D. Constant fertility and zero migration
Discuss
Get Complete Subject PDF for Accountancy and Statistics

Correct Answer: Option D

Explanation:
NRR=1.0 means each generation of women exactly replaces itself with daughters surviving to reproduction; with constant fertility/mortality and no migration, population growth ceases in the long run.
