The Net Reproduction Rate (NRR) of a population is exactly 1.0. This indicates that:

• A The total fertility rate equals 2.1 currently
• B The population will exactly replace itself (stationary population in long run) ✓
• C The population is growing at replacement level right now
• D Each generation produces exactly one female who survives to reproduce

Explanation

NRR measures the average number of daughters born to a woman who survive to reproductive age, accounting for mortality. NRR = 1.0 means exact generational replacement — each woman is replaced by exactly one surviving daughter. Population growth rate depends on NRR over time; NRR = 1.0 implies eventual population stabilization after a demographic lag. Unlike GRR, NRR accounts for mortality.
