Replacement fertility is the total fertility rate at which women give birth to enough babies to sustain population levels, assuming that mortality rates remain constant and net migration is zero. [8] If replacement level fertility is sustained over a sufficiently long period, each generation will exactly replace itself. [8]

Along with mortality rate, natality rate is used to calculate the dynamics of a population. They are the key factors in determining whether a population is increasing, decreasing or staying the same in size. Natality is the greatest influence on a population's increase. Natality is shown as a crude birth rate or specific birth rate.
