牲畜是发展中国家农村生计的一个重要组成部分，但由于许多牧民的游牧和半游牧性质，很难收集关于这一收入和财富来源的数据。大多数住户调查不包括那些没有永久住所的人，导致覆盖不足。本研究探讨了使用随机地理集群样本作为替代以家庭为基础的样本。在这种设计中，点是随机选择的，所有符合条件的受访者都在所选点周围画的圆圈内接受采访。这一办法应消除对移动的人口的覆盖不足。本报告介绍了2012年在埃塞俄比亚阿法尔地区进行的一项随机地理群组抽样调查的结果，总样本量为784户，以衡量牲畜所有权。本文探讨了相对于最近的住户调查的随机地理聚类样本的数据质量，并讨论了实施的挑战。
Livestock are an important component of rural livelihoods in developing countries, but data about this source of income and wealth are difficult to collect because of the nomadic and semi-nomadic nature of many pastoralist populations. Most household surveys exclude those without permanent dwellings, leading to undercoverage. This study explores the use of a random geographic cluster sample as an alternative to the household-based sample. In this design, points are randomly selected and all eligible respondents found inside circles drawn around the selected points are interviewed. This approach should eliminate undercoverage of mobile populations. The results of a random geographic cluster sample survey are presented with a total sample size of 784 households to measure livestock ownership in the Afar region of Ethiopia in 2012. The paper explores the data quality of the random geographic cluster sample relative to a recent household survey and discusses the implementation challenges.
