Fertility related statistics | Definition |
Total fertility rate (TFR) | Measures the overall fertility rate without differentiating between genders. |

Net reproductive rate (NRR) | Measures the rate of producing female offspring while accounting for mortality, indicating whether a population is growing, shrinking, or remaining stable. |
