Total Fertility Rate (TFR) is a average number of children that would be born to a woman if she experiences the current fertility pattern throughout her reproductive span (15-49 years). The total fertility rate is a more direct measure of the level of fertility than the birth rate, since it refers to births per woman. This indicator shows the potential for population change in a country. A TFR, two children per women is considered the replacement rate for a population, resulting in relative stability in terms of total population numbers.
