The WASH Performance Index Report
- The Water, Sanitation, and Hygiene (WASH) Performance Index is a comparison of country performance in realizing universal WASH. The WASH Performance Index assesses performance in the following components: water access, water equity, sanitation access, and sanitation equity.
- The top five performing countries in the 2015 WASH Performance Index rankings are El Salvador, Niger, Egypt, Maldives, and Pakistan. The bottom five performers are the Dominican Republic, Gambia, Ghana, Samoa, and Timor-Leste.
- Progress toward equity in sanitation is significantly associated with governance indicators including control of corruption, government effectiveness, regulatory quality, and rule of law. These results suggest the enabling environment for WASH contributes to progress in sanitation equity.
- Water access performance among countries in Sub-Saharan Africa varies widely, despite their having the lowest water coverage in the world.
- Among the world’s most populated countries, Pakistan, China, and Nigeria were top performers (ranked 5, 11, and 18 respectively). Russia, the Philippines and India were bottom performers (ranked 72, 83, and 92 respectively).
- Despite the assumption that countries with higher GDP will perform better in improving access to water and sanitation, GDP was not significantly correlated with performance.
- Among most top performing countries, neither water nor sanitation dominated the overall Index value, suggesting improvements in water or sanitation do not come at the expense of the other.
