Map of countries by fertility rate (2018), according to the CIA World Factbook.

The total fertility rate (TFR), sometimes also called the fertility rate, absolute/potential natality, period total fertility rate (PTFR), or total period fertility rate (TPFR) of a population is the average number of children that would be born to a woman over her lifetime if:

  1. She was to experience the exact current age-specific fertility rates (ASFRs) through her lifetime, and
  2. She was to survive from birth to the end of her reproductive life.

It is considered a better measure of fertility than the birth rate (annual number of births per thousand population) because it is independent of the age structure of the population.
