全球卫生和国际发展领域通常按地理位置和收入将各国归类，以确定资源目标并描述进展情况。对于任何特定的感兴趣的部门，一系列相关指标可以作为更适当的分类基础。我们根据与水和卫生设施(WatSan)相关的多个指标的相似性，创建了一种针对水和卫生(WatSan)部门的国家集群的新类型。在查阅文献和咨询WatSan部门的专家后，选定了9项指标。指标选择的依据是与国家水和卫生服务提供的相关性和对其的建议影响，以及尽可能多的国家最大限度地提供数据。采用等级聚类法和差距统计分析将各国分组为自然数量的相关分组。两个阶段的分组产生了五个分组，代表156个国家或67.5亿人口。这五个专题组没有按收入或地理位置很好地加以解释，而且有别于国际发展中使用的现有国家专题组。对这五个专题组的分析表明，它们比联合国和世界银行的国家专题组更为紧凑和分散。这一分析和由此产生的国家分类表明，可以通过利用全球可用的与WatSan有关的指标，改进以前基于地理或收入的国家分组，用于WatSan部门的应用。潜在的应用包括指导和讨论研究，为政策提供信息，改进资源定位，描述部门进展，以及确定WatSan部门的关键知识差距。
The fields of global health and international development commonly cluster countries by geography and income to target resources and describe progress. For any given sector of interest, a range of relevant indicators can serve as a more appropriate basis for classification. We create a new typology of country clusters specific to the water and sanitation (WatSan) sector based on similarities across multiple WatSan-related indicators. After a literature review and consultation with experts in the WatSan sector, nine indicators were selected. Indicator selection was based on relevance to and suggested influence on national water and sanitation service delivery, and to maximize data availability across as many countries as possible. A hierarchical clustering method and a gap statistic analysis were used to group countries into a natural number of relevant clusters. Two stages of clustering resulted in five clusters, representing 156 countries or 6.75 billion people. The five clusters were not well explained by income or geography, and were unique from existing country clusters used in international development. Analysis of these five clusters revealed that they were more compact and well separated than United Nations and World Bank country clusters. This analysis and resulting country typology suggest that previous geography- or income-based country groupings can be improved upon for applications in the WatSan sector by utilizing globally available WatSan-related indicators. Potential applications include guiding and discussing research, informing policy, improving resource targeting, describing sector progress, and identifying critical knowledge gaps in the WatSan sector.
