The total fertility rate (TFR), sometimes also called the fertility rate, 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
- she were to experience the exact current age-specific fertility rates (ASFRs) through her lifetime, and
- 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.

“only total expression
expresses hiding: I’ll have to say everything
to take on the roundness and withdrawal of the deep dark:
less than total is a bucketful of radiant toys.”
—Archie Randolph Ammons (b. 1926)
“Dancing with abandon, turning a tango into a fertility rite.”
—Marshall Pugh (b. 1925)
“Unless a group of workers know their work is under surveillance, that they are being rated as fairly as human beings, with the fallibility that goes with human judgment, can rate them, and that at least an attempt is made to measure their worth to an organization in relative terms, they are likely to sink back on length of service as the sole reason for retention and promotion.”
—Mary Barnett Gilson (1877–?)
