Summary An attempt has been made to measure the effect of age at marriage of brides on the timing of the first birth. In Australian vital statistics, first nuptial confinements have been tabulated by age of mothers and by single years of marriage duration in single months for the first two years and by single years for all other durations since 1916. A simple technique has been used to link such data with marriage cohorts. The study briefly reviews the prevailing patterns of the timing of first births by mothers' age at marriage and changes in this pattern since the marriages of the 1925/9 period. The analysis shows that after a period of relative stability of family formation patterns in the 1950s and early 1960s, women married in the late 1960s started postponing the first birth beyond the first two years of marriage. It is suggested that a fraction of the decline in total births recorded in Australia since 1972 can be attributed to the postponement of first nuptial confinements by women married in the late 1960s and early 1970s.
摘要 本研究旨在衡量初婚年龄对首次生育时间的影响。在澳大利亚生命统计数据中，1916 年以来，头胎初产妇的年龄和初婚持续的单年数按月被单独列出，头两年的初婚持续时长为单月，其余时长则按年列出。本研究采用了一种简单的技术将这些数据与婚姻队列联系起来。本研究简要回顾了母亲初婚年龄与首次生育时间的流行模式以及自 1925/9 年以来这一模式的变化。分析表明，在 20 世纪 50 年代和 60 年代初家庭形成模式相对稳定之后，20 世纪 60 年代末结婚的女性开始将首次生育推迟到婚后两年之后。研究认为，自 1972 年以来澳大利亚总生育率下降的部分原因可以归因于 20 世纪 60 年代末和 70 年代初结婚的女性推迟了首次分娩。
