Natality is the rate at which new individuals are added to a population in a unit of time.
Natality or birth rate is the rate of production of new individuals per unit of population per unit of time through birth, hatching, germination, and vegetative propagation. If the natality rate increases the mortality rate of the population rapidly increases.
