Abstract: The purpose of the study is to determine how water point level estimates for rural basic water service coverage from the Water Point Data Exchange (WPdx) compare to the household level estimates from the Joint Monitoring Programme of WHO/UNICEF (JMP) in multiple geographies. The study describes how these different estimates are produced and proposes the comparison of JMP basic minus services on premises to WPdx basic access. WPdx basic access estimates the population with 1km of an improved water point. Comparing between metrics and triangulating different measured results can be useful to validate conclusions and inform decision making. This study finds a relatively strong correlation and linear trend between these two estimates in four countries that suggests that using household surveys and water point inventories together can be useful to decision makers who may only have one or the other data sources or may want to validate the conclusions from one against another. The WPdx basic estimates allow a more granular geographical level of access estimates that can be useful to districts and enable national vulnerability assessments. This could strengthen the type of analysis provided in JMP inequality charts showing the differences between country regions. At the same time, further research is needed to validate these trends at these lower geographical levels. Rural water leaders, including national and local governments, development partners, service providers and civil society should continue to advocate for the publication of water point data and the validation of access estimates on the basis of publicly available information. This plays an important role in improving the quality of both public and private data sets and analyses used by researchers and decision makers.
