Total Fertility Rate (TFR) TFR is a measure of fertility that summarizes the rate of childbearing in a given period of time, often a year. It is derived by summing the age-specific birth rates for a population of women in a given period. The TFR is also a hypothetical measure of completed fertility for a synthetic cohort of women assumed to pass through life bearing children according to the age-specific birth rates in a given period. Thus, the TFR may be interpreted as the average number of lifetime births women may be expected to have if they bore children at the rates that women of all ages did in the given year or other period.
