The interval between marriage and the first birth in India, particularly in rural areas, is much longer than what is observed in western countries. In eastern Uttar Pradesh, the mean interval is observed to be even longer, possibly due to traditional customs such as the female partner's visits to her parents in the early years of marriage and the smaller chance of coition because of the observance of rigid intercourse taboos. Thus the models to explain the length of the interval of marriage to first birth proposed by Western demographers, which assume that the period of cohabitation between marriage and first birth is uninterrupted, often do not describe the data satisfactorily when applied to rural India. In this paper a model to describe data on first birth interval is proposed that takes account of the distributions of timing and periods of physical separation and variation in fecundity with effective marriage duration.
在印度，尤其是农村地区，结婚与首次生育之间的间隔时间比西方国家要长得多。在印度北方邦东部，平均间隔时间甚至更长，这可能是由于一些传统习俗，比如女性伴侣在婚后早期会回娘家，以及由于严格遵守性交禁忌而导致性交机会较少。因此，西方人口统计学家提出的用以解释结婚至首次生育间隔时间长度的模型，假设结婚与首次生育之间的同居期是不间断的，但在应用于印度农村时，往往无法令人满意地描述相关数据。本文提出了一个描述首次生育间隔时间数据的模型，该模型考虑了身体分离的时间和周期分布以及生育力随有效婚姻持续时间的变化。
