The paper discusses the reproductive life of 111 ever-married Bhoksa women. The mean age at marriage for women of all ages among Bhoksas, like other tribal populations, is high, unlike the caste populations. The mean ages at first birth of the pooled sample and of the completed fertility cases suggest late and early marriages of the older and younger generations. The maximum number of marriages occur between 15 and 19 years and of first births between 16 and 20 years. Percentage of reproductive wastage is high in both the lower and higher age groups. Young mothers with low birth orders and older mothers with high birth orders display a high frequency of reproductive wastage. Evidently, both birth order and the age of the mother have effects on reproductive wastage. Average number of children ever born (including stillbirth but not abortion or miscarriage) per mother of all ages is the highest among Bhoksas of all the studied ethnic groups of India. The Bhoksa, like caste populations, show a high number of children ever born per mother of completed fertility. Quite a high masculinity in the secondary sex ratio, like other mongoloid population is noticed. The contribution of mortality component to the Total Index of Opportunity for Selection is more than that of the fertility component. Bhoksas conform to the general low range of net reproductive index, which is however greater than unity, suggesting that they are in a growth stage.
本文讨论了111名曾经结婚的博克萨族女性的生育情况。与其他部落人口一样,博克萨族各年龄段女性的平均初婚年龄较高,与种姓人口不同。汇总样本和已完成生育案例的平均初育年龄表明,老一代和年轻一代结婚较晚且生育较早。结婚最多的年龄在15至19岁之间,初育年龄在16至20岁之间。较低和较高年龄组的生殖损耗百分比都很高。低生育顺序的年轻母亲和高生育顺序的年长母亲生殖损耗频率较高。显然,生育顺序和母亲年龄都会对生殖损耗产生影响。在印度所有研究的族群中,博克萨族各年龄段每位母亲的平均子女数(包括死产但不包括流产或堕胎)是最高的。与种姓人口一样,博克萨族已完成生育的每位母亲的生育子女数也很高。与其他蒙古人种群体一样,观察到第二性别比中的男性比例相当高。死亡因素对总选择机会指数的贡献大于生育因素。博克萨族符合净生殖指数普遍较低的范围,但该指数大于1,表明他们正处于增长阶段。
