The net reproduction rate (711-3) and the intrinsic rate of natural increase (703-1) are closely related to one another. The net reproduction rate will measure the increase of the stable population (703-2) implied by the given age-specific fertility and mortality rates (401-2), over a period equivalent to the length of a generation1 or the mean interval between successive generations1. This length of a female generation is approximately equal to the average age of mothers2 giving birth to live daughters, provided current age-specific fertility and mortality rates prevail. Replacement indices are generally current indices (cf. 153-4) which relate to hypothetical cohorts3, fictitious cohorts3 or synthetic cohorts3.
