Summary Brass's procedure for estimating mortality from census or survey data on numbers of children born to women by age group and numbers of children surviving is generalized to allow the estimation of mortality trends. The new procedure is applied to data for Costa Rica and peninsular Malaysia. The resulting infant mortality rate estimates are compared with rates calculated from vital registration figures. The comparisons suggest, surprisingly, that the estimates derived from statistics for women aged 30-50 are not noticeably inferior to those derived from those for women aged 20-30. This suggests that the common practice of disregarding statistics for women aged over 30 or 35 years may be a mistake. Figures are presented which suggest that estimates based on women aged less than 20 are likely to be very seriously biased because of differential infant mortality by age of mother at birth.
Brass 提出了一种方法，通过对按年龄分组的妇女生育子女数量和存活子女数量的人口普查或调查数据进行估算，来估计死亡率趋势。本文将该方法进行了推广，应用于哥斯达黎加和马来半岛的数据中。利用该方法对婴儿死亡率进行了估算，并与根据生命登记数据计算出的死亡率进行了比较。结果令人惊讶，与根据 20-30 岁妇女生育数据计算出的结果相比，根据 30-50 岁妇女生育数据计算出的婴儿死亡率估计值并没有明显差异。这表明，通常忽略 30 岁以上或 35 岁以上妇女生育数据的做法可能是错误的。本文还提供了一些数据，表明根据年龄小于 20 岁的妇女生育数据进行估算可能会存在严重的偏差，因为不同年龄的母亲所生婴儿的死亡率存在差异。
