요약	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 mean age at childbearing is the average age of mothers at the birth of their children, computed as the fertility-rate-weighted mean of maternal age over the age-specific fertility schedule. As the first moment of the fertility curve, it summarizes the tempo — the timing — of childbearing in a single number, complementing the total fertility rate, which measures quantum, or how many children are born.
