AbstractData on the last closed and open birth intervals have been used to ascertain the current potential of childbearing for women in terms of estimating fecundity and secondary sterility by age, residence, and educational subgroup. Under the assumption that after a specific period from the last birth a certain proportion of women become secondarily sterile, we propose and apply an inflated model of open birth interval to obtain the proportion of women who are secondarily sterile. The data used for the analysis are extracted from the Egyptian Fertility Survey conducted in 1980.
