Information about health and family planning infrastructures is collected through the service availability module (SAM), an important feature of the Demographic and Health Surveys (DHS) conducted in many developing countries. The DHS samples were designed to provide a representative sample of households and women of reproductive age. Using the weights routinely provided with DHS data sets, service accessibility can be described straightforwardly at the individual and household levels. However, without further adjustment, SAM data do not provide a representative picture of service delivery at the community, or primary sampling unit, level, where the data are collected. This report proposes a methodology for reweighting the SAM data, using rural data from the Egypt DHS as an illustration, so that available family planning facilities at this level may be usefully characterized at little additional cost.
关于卫生和计划生育基础设施的信息是通过服务可及性模块（SAM）收集的，该模块是在许多发展中国家进行的人口与健康调查（DHS）的一个重要特征。DHS样本旨在提供具有代表性的家庭和育龄妇女样本。利用DHS数据集常规提供的权重，可以直接描述个体和家庭层面的服务可及性。然而，如果不做进一步调整，SAM数据无法提供在收集数据的社区或初级抽样单位层面的服务提供情况的代表性图景。本报告提出一种对SAM数据进行重新加权的方法，并以埃及DHS的农村数据为例进行说明，以便能够以很少的额外成本有效地描述该层面现有的计划生育设施。
