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

It is obtained by summing the single-year age-specific rates at a given time.
