Zhrnutie	The own-children method is an indirect technique for estimating age-specific fertility rates for the years preceding a census or survey, using only a single cross-sectional dataset in which children can be linked to their mothers within the same household. By reverse-surviving matched mother-child pairs back through time, it reconstructs annual birth rates and total fertility for roughly the previous 15 years without requiring any vital-registration data on births.	The net reproduction rate (NRR) is the demographic measure of generational replacement: the average number of daughters a woman would bear who survive to the age their mother was when she bore them, given the period's age-specific fertility rates and female mortality. By combining fertility with survival, the NRR answers the fundamental question of whether a population is replacing itself — an NRR of one means each generation of women exactly reproduces the next, below one signals long-run decline, and above one signals growth.
