Demographic effects of sex preselection
The demographic effects of sex preselection technology are studied by means of mathematical models for completed family size and the sex ratio at birth. It is shown that in the case of an indefinite amount of time available to achieve desired family composition, sex preselection has a substantial effect on completed fertility. When a finite reproductive period is introduced (for example, due to distributions of age at marriage and secondary femal…
Sequence of events following adoption of contraception
Fertility histories from the 1973 United States National Survey of Family Growth are analyzed in the context of a model of contraceptive use based on a Semi‐Markov processes. This model provides a means of constructing data‐based estimates of probabilities of pregnancy following initial acceptance of a contraceptive method. The algorithm used to construct these estimates recognizes multiple intervals of contraceptive used prior to the events: pre…
