The first survey designed to allow estimates of the demographic characteristics of Afghanistan's sedentary population was conducted during the period 1972-1974. Our analysis of these data, based on recently developed techniques for handling imcomplete or inaccurate data, suggests that this population lives under conditions that are extreme when judged by modern standards. Marriage is early, especially for females, and universal. Marital fertility conforms to a pattern of natural fertility and total fertility is high. The birth rate is among the highest in the world today, and the expectation of life at birth is among the very lowest. Mortality is lower in urban areas than in rural areas, whereas total fertility is approximately the same in both. Our estimates of fertility and mortality imply stable populations which match closely the observed age distributions for both the rural and urban areas.
1972年至1974年期间进行了首次旨在估算阿富汗定居人口人口特征的调查。我们基于最近开发的处理不完整或不准确数据的技术对这些数据进行的分析表明，按照现代标准判断，这部分人口生活在极端条件之下。结婚很早，尤其是女性，而且结婚是普遍现象。婚内生育符合自然生育模式，总和生育率很高。出生率是当今世界最高的之一，出生时预期寿命则是最低的之一。城市地区的死亡率低于农村地区，而两地的总和生育率大致相同。我们对生育率和死亡率的估算意味着人口稳定，这与农村和城市地区观察到的年龄分布非常吻合。
