Total Fertility Rate (TFR)
Definition
The total fertility rate is the average number of children a woman would have if she were to live to the end of her childbearing years and bear children according to current age-specific fertility rates.
Analogy
Think of TFR as a forecast for a family tree. It's like predicting how many branches (or children) will be added to the family tree based on current conditions.
