3.7 Total Fertility Rate
Notes
Total fertility rate (TFR): average number of children per woman. Replacement level is about 2.1.
- TFR falls with education for women, access to family planning, and economic development.
- Infant mortality rate affects TFR.
Practice
TFR below 2.1 over time leads to:
Below replacement.
Which tends to lower TFR?
Women have more choices.
Why is replacement level slightly above 2?
