The decline in fertility in England and Wales since 1964
The decline in the number of legitimate live births in England and Wales from the peak in 1964 has been partitioned into components due to changes in fertility rates, components due to changes in the composition of the population exposed to risk, and an interaction component. Fertility rates specific for age of mother at birth of child, duration of marriage, parity and age of mother at marriage were considered but in all cases it was found that t…
The interval between confinements
Data from New South Wales are analysed to show how the interval between confinements depends on the parity of the mother. When an average interval is calculated it is a weighted average for mothers of varying parity. The weights depend in part on the parity progression ratios and as changes in the parity progression ratios alter the composition of the population by parity, this affects the weightings used and thus affects the average interval obt…
The independence of the intervals between confinements
The distribution of the interval between (say) first and third confinements is the product of the distributions of the intervals between first and second and second and third confinements provided these two confinement intervals are independent. In this paper we use some specially provided NSW data to consider the question of the independence of the intervals between various confinements. It is shown that there is some indication of a positive as…
Factors influencing the sex ratio at birth in Australia, 1902–65
Using Australian records of human births for the first six decades of the twentieth century, the proportions of male and female births are studied in relation to the mother's age, the father's age, the parents' ages in combination, and certain other factors. The principal data used relate to the years 1931–55, during which over 3 million children were born, yet even so the significant features are not easy to discern. Masculinity tends to fall as…
Multiple births in Australia, 1944–63
From statistics on Australian confinements during the period 1944–63 it seems that the following conclusions can legitimately be drawn: (1) The proportion of multiple births increases with increasing age of mother up to about age 37, turns, and decreases thereafter. (2) The proportion of multiple births increases with increasing age of father up to about age 34–38 and is fairly constant thereafter. (3) The variation with age of father, however, o…
