Country Clustering Applied to Water and Sanitation

Water and sanitation practitioners commonly group countries into geographical or economic subdivisions to describe progress and target resources. In the International Journal of Hygiene and Environmental Health, researchers at The Water Institute propose a new way to categorize countries. ​The new approach uses statistical cluster analysis to group countries based on a range of indicators relevant to the water and sanitation sector that can be used to improve resource targeting and progress description.
