Tracking progress towards global drinking water and sanitation targets: a within and among country analysis

Use of improved drinking water and sanitation has increased globally during the last 15 years. However, progress and the degree of inequality both vary widely between countries. We assessed temporal patterns in access to water and sanitation using publicly available data and classified their trajectories into one of nine categories. We found that progress varied greatly between countries and was usually characterized with progress being slow at low levels of coverage, fast at intermediate levels of coverage, and again slow at high levels of coverage. Characterizing trajectories helps identify countries that are stagnating and in need of increased financing or institutional support.
