The study of reproduction 1 or population replacement 1 is concerned with the natural process through which a population replaces its numbers. A distinction is drawn between gross reproduction 3 or gross replacement 3, where no account is taken of mortality before the end of the reproductive period (620-1), and net reproduction 4 or net replacement 4, in which this mortality is taken into account.
