| Popis: | This paper revisits and extends an inquiry on the age-at-menarche differential fecundity hypothesis. Earlier studies have interpreted the difference in the onset of female pubertal maturation as indicative of biological differences in fecundity between early and late menarcheal women. Using the WFS data for Sudan, the authors address the entire reproductive life of the women in terms of their transition from one parity to the next, as well as the speed with which birth intervals are closed, as a way to infer biological fecundity among the women. The study concludes that there is little evidence that early menarcheal women are more fecund than their late puberty counterparts.Earlier studies have interpreted the difference in the onset of female pubertal maturation as indicative of biological differences in fecundity between early and late menarcheal women. The authors examine the ways in which the reproductive behavior of a woman is determined by how early or late in adolescence she enters puberty. Addressing the entire reproductive life of women, the authors study the transition from one parity to the next, as well as the speed of timing of reproduction, using birth intervals and parity progression ratios from which biological fecundity among women may be inferred. World Fertility Survey data for Sudan collected between December 1978 and April 1979 are used. Little evidence is found that early menarcheal women are more fecund than their late puberty counterparts. |
