Why This Ranking Matters
Examining Basic Sanitation Access across all countries reveals patterns that might not be obvious at the national level. Regional clusters, outlier nations, and historical trajectories all become clearer when the full global picture is assembled in a single ranking.
Global Range
Values range from 10.36% (Ethiopia) to 100% (Andorra) — a 10-fold difference across 202 countries.
Regional Patterns
European countries lead with 8 entries in the top 20, though representation spans multiple continents. Regional factors clearly play a role, but outliers from other parts of the world show that national policy and geography matter as much as continental trends.
Values are broadly distributed across countries, with the middle 50% ranging from 67.62% to 99.07%. The overall spread from 10.36% to 100% reflects significant global variation.
Notable Outliers
The top of the ranking is competitive: Andorra and Australia are separated by only 0%, indicating that the leading positions could shift with updated data. The bottom five countries are all from Africa, pointing to regional challenges that affect basic sanitation access across the continent.
