A country's Total Fertility Rate (TFR) is 3.2 children per woman. The Net Reproduction Rate (NRR) is 1.5. This means the country is in a stage of:

• A Population decline — births less than replacement level
• B Population growth — each generation produces 1.5 daughters per woman ✓
• C Population stagnation — NRR = 1 indicates replacement fertility
• D Demographic transition Stage 4 (low birth, low death rates)

Explanation

Net Reproduction Rate (NRR) is the average number of daughters a woman would bear if she experienced the current age-specific fertility and mortality rates throughout her reproductive life. NRR > 1 indicates population growth (more than one daughter per woman reaching reproductive age). NRR = 1 represents exact replacement (stationary population); NRR < 1 indicates eventual population decline. An NRR of 1.5 means each woman contributes 1.5 daughters to the next generation, indicating significant population growth. India's NRR fell below 1.0 around 2019-2020 in some states, signaling replacement-level fertility in those regions.
