The net population reproduction rate is an indicator that characterizes the birth rate in a population in the absence of the influence of mortality.
It shows how many girls each woman will give birth to on average during her entire reproductive period, assuming there is no mortality. In other words, the net replacement rate reflects the fertility potential of a population.
If the value of this coefficient is 1, then the population size remains stable, since each woman on average gives birth to exactly 1 girl in her life. If the coefficient is greater than 1, then the population is growing, if less than 1, it is declining.
Thus, the net replacement rate of the population gives an idea of the reproductive capabilities of the population and trends in its growth or decline, without taking into account the influence of mortality.
