Fertility related statistics

1. Crude birth rate (CBR) - Simplest indicator of fertility

2. General fertility rate (GFR)

3. General marital fertility rate (GMFR)

4. Total fertility rate (TFR)

5. Gross reproductive rate (GRR)

6. Net reproductive rate (NRR) - Best indicator of fertility

Fertility related statistics	Definition
Crude Birth Rate (CBR)	The number of live births per 1,000 people in a given year.
General Fertility Rate (GFR)	The number of live births per 1,000 women of childbearing age (typically ages 15-49) in a given year.
General Marital Fertility Rate (GMFR)	The number of live births per 1,000 married women of childbearing age (typically ages 15-49) in a given year.

Fertility related statistics	Definition
Total fertility rate (TFR)	measures the overall fertility rate without differentiating between genders.
Gross reproductive rate (GRR)	measures the rate of producing female offspring without accounting for mortality.
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.
