Estimators of a type I geometric distribution from observations on conception times
In order to study distributions of fecundability, Potter and Parker fitted a Pearson Type I geometric distribution (with parametersa andb) to data from the Princeton Fertility Study. They, and subsequently other authors, estimateda andb from the observed moments of the month of first conception. A critical analysis of this method has shown that moment estimators ofa andb are moderately reliable only within a specified range of values ofa. Outside…
Probability models for family building
Considerable literature now exists on stochastic models for the reproductive history of a cohort of couples. These models are of varying complexity and the relationships between separate treatments are not always clear. A classification system for such models is proposed, followed by a historical review of models for family building and for logically related processes. Models, differing only in treatment of time as discrete or continuous, are pre…

Contributions of natality models to program planning and evaluation
This paper is an attempt to describe and assess the contributions made by the newer quantitative models of natality to program planning and development. Considerable interest in models of natality is being reflected in reports of a large variety of ideas, suggestions, and proposed models. In view of this current activity, any assessment made now of the contributions of these models can be only tentative and should consider also prospects for the …
An analytic simulation model of human reproduction with demographic and biological components
This Monte Carlo model for simulating the reproductive history of a cohort of women is described in detail. The model provides for patterns of survival, sterility, formation and dissolution of sexual unions, fecundability, lactation, foetal wastage, family planning practices etc. Natality indices specific for marital status, for duration of marriage and for age, as well as analyses of birth spacing patterns are among the results that may be obtai…

An analysis of reproductive patterns in an American isolate
The reproductive patterns of an American Anabaptist group with high birth rates and which apparently does not practise deliberate limitation of family size are characterized by short intervals between successive births. The mean intervals tend to increase in length with maternal age (or rising birth order), but they are under two years for the first 10 births. In agreement with conclusions suggested by theoretical models, the data indicate that t…
Pregnancy wastage as a factor in the analysis of fertility data
Esteestudio considera el efecto delas muertes fetales en las tasasdefecundidad y en lasinferencias derivadas de ellas, utilizando un modelo estocdstico para la fecundidad humana. El modelo proporciona una probabilidad eepecifica para un numero de diferentes resultados de la concepcion, por ejemplo, muertesfetales esponianeas (tempranas y nacidosmuertos) nacidos vivos y abortos inducidos. La duraci6n del embarazo se tomacomo una variable cuya dist…
Pregnancy Wastage as a Factor in the Analysis of Fertility Data
The distribution of birth intervals under a class of stochastic fertility models
Characterization ofthe distribution ofintervals between successive births affords both practical and theoretical advantages in the analysis of fertility data. Moreover, attempts to formulate a mathematical model describing the process of reproduction lead naturally to a consideration of the distribution of birth intervals. A class ofmodels has been formulated, applying to a woman who is not pregnant and fecundable at marriage and who after a vari…
On the time required for conception
The purpose of this paper is to investigate some characteristics of rates of conception in a mixed or heterogeneous population. Consider that one has data showing, for a sample of couples, the number of women conceiving in each consecutive month of observation. These data on the monthly incidence of conception may be used to characterize the fecundability (monthly chance of conception) of the couples or to estimate the effectiveness of a contrace…

Effects on family size and sex ratio of preferences regarding the sex of children
If the desired size of a family is specified in terms of sex composition, the sex preferences may affect eventual family size. Assuming that a couple wish to have a specified minimum number of boys and of girls, and continue to have children until these minimum numbers are reached (with perhaps an upper limit), formulae and numerical calculations are presented for the average size of family. In most cases, there is more than an even chance that t…
