Resumé	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 total fertility rate (TFR) is the central period measure of fertility in demography: the average number of children a woman would bear over her lifetime if she experienced, at each age, the age-specific fertility rates observed in a given year. Computed by summing age-specific fertility rates across the reproductive ages, the TFR removes the influence of population age structure and gives a single, intuitive figure — children per woman — that is comparable across populations and over time.
