Tiivistelmä	The Bongaarts framework of the proximate determinants of fertility decomposes a population's fertility into a biological maximum reduced by a small set of directly fertility-inhibiting factors: the proportion of women in sexual unions, contraceptive use, induced abortion, and postpartum infecundability. By expressing observed fertility as total fecundity multiplied by four indices between zero and one, it quantifies how much each behavioural and biological channel suppresses fertility below its potential ceiling.	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.
