The Net Reproduction Rate (NRR) of exactly 1.0 implies which demographic condition?
- A The population will double in one generation
- B The crude birth rate equals the crude death rate
- C Each woman is replaced by exactly one daughter, indicating replacement-level fertility and a stationary population in the long run ✓
- D The Total Fertility Rate (TFR) equals 2.1
Correct answer: C. Each woman is replaced by exactly one daughter, indicating replacement-level fertility and a stationary population in the long run
Explanation
NRR = 1.0 means each woman is on average replaced by exactly one daughter who survives to reproductive age, indicating replacement-level fertility. In the long run, NRR = 1.0 leads to a stationary population (neither growing nor declining). NRR < 1.0 implies below-replacement fertility and eventual population decline; NRR > 1.0 implies population growth. NRR accounts for female-to-female replacement and survival to reproductive age, unlike the Gross Reproduction Rate (GRR) which ignores mortality.
