The WASH Performance Index Report - Sanitation Access

Country performance in improving sanitation access

• Country rates of change (progression or regression, percent per year) in access to sanitation were compared to the performance frontier (best-in-class performance) to generate a country value for performance in improving sanitation access.
• Country performance in sanitation access is significantly and positively associated with the South Asia region, suggesting countries from this region are performing better (progressing more rapidly).
• Top performing countries are Jordan, Malawi, Egypt, Uzbekistan, South Africa, China, Tanzania, Jamaica, Nepal, and Sri Lanka.
• Bottom performing countries are Ghana, Sierra Leone, Costa Rica, Timor-Leste, Vanuatu, Democratic Republic of the Congo, Belarus, Thailand, Samoa, and Estonia.

Country rates of change (progression or regression, percent per year) in access to sanitation were compared to the performance frontier (best-in-class performance) to generate a country value for performance in improving sanitation access. Values for sanitation access performance were calculated for 133 countries. Figure 12 summarizes the values.
