Systematic and chance components in fertility measurement
A Monte Carlo simulation model of fertility is developed to incorporate a decline in fecundability with age of women as well as a variation between women, and a family planning strategy in which couples prefer certain sizes of families and seek to lengthen the last planned birth interval. In the simulation of family planning and non-family planning populations, segmental parity tables are computed. These are tables in which the numbers of women i…

Report of the Population Growth Estimation Experiment
Demography and Economics
In industrialized societies such as the U.K., demographic, social and economic characteristics and changes are closely interrelated, but the study of their interconnections is often strangely neglected. Demographic research and economic research are too often carried out in separate compartments: and the same is true of teaching in the two subjects. Economists work on many problems which have important demographic aspects, without a full apprecia…

The graduation of fertility distributions by polynomial functions
There are a number of situations in which it is useful to graduate fertility distributions; for example when the data are obtained from small samples of the population, or when it is desired to translate age-specific fertility rates into ratios of total children ever born per woman in an age group or vice versa. Usually it is convenient to work with rates for five-year age groups of women since the effects of errors due to age mis-statements and …
The distribution of births in human populations in rural Taiwan
Two models to represent the distribution of births in human populations are examined. It is assumed that births occur at random over a fixed exposedto-risk age period at an expected rate which is constant for each mother but varies among them in a Pearson type III form. This leads to a truncated negative binomial distribution of mothers of completed fertility by number of births, or a more complex modification of this distribution, according to w…
The Distribution of Births in Human Populations
Progress in the biometrical sciences has been greatly stimulated by the study of mathematical models which have been constructed to represent approximately events and processes. This approach often leads to a deeper understanding of underlying factors and suggests useful methods of collecting describing and analysing data. In demography there have been fewer attempts to construct models than in other branches of biometry. Perhaps the main reasons…
The estimation of fertility rates from ratios of total to first births
In a previous paper a formula was derived from which the total fertility rate of a group of women could be estimated from the average number of live births to women in the reproductive period. In the present paper the argument is carried further and a method is given by which the total fertility rate may be estimated from the average number of children born to fertile women during the reproductive period. The method given in this paper may, under…
The derivation of fertility and reproduction rates from restricted data on reproductive histories
In this paper, the author considers a method of obtaining demographic constants for populations for which very scanty statistics only are available. By assuming that the age distribution of the female population may be approximated by a Taylor series, he obtains certain statistics which approximate to the conventional reproduction rates. The implications of his analysis are discussed and the methods are applied to the data given in the Demographi…
