This paper examines the patterns of timing of births of women using data from the Canadian Fertility Survey of 1984. Semi-Markovian schemes are applied to the maternity histories of the 5315 sample women in their reproductive ages in order to measure the intensity and timing of childbearing. Age-and-duration-specific transition probabilities are found to have substantially changed for the more recent birth cohorts compared to the older cohorts.
本文利用1984年加拿大生育调查的数据，研究了女性的生育时间模式。半马尔可夫模型被应用于5315名处于生育年龄的样本女性的孕产史，以衡量生育强度和生育时间。结果发现，与较早的队列相比，较近期出生队列的年龄和生育间隔特定转移概率发生了显著变化。
