Total fertility rate

The total fertility rate is obtained by adding up the fertility rates calculated for one year. The rate refers to the estimated number of children born to a woman, given that the fertility rate of that statistical year prevails during the whole reproductive period of this woman on condition that the woman does not die before the end of the said period.

Gross reproduction rate

The reproduction of the population refers to a change of a generation into a new one. Reproduction is measured by gross reproduction rates or net reproduction rates that generally indicate the ratio between the sizes of the daughter's and mother's generations. In the gross reproduction rate mortality of the mother's generation before the end of the childbearing age is not taken into account in the calculation. If the gross reproduction rate calculated per woman is less than one, the daughter's generation is smaller than the mother's generation and the mother's generation has not reproduced itself.
