How this figure is calculated
People not using improved sanitation facilities divided by Land area (sq. km), matched on country and year. Neither publisher issues this ratio as a series; it is computed here from both.
People not using improved sanitation facilities ÷ Land area (sq. km)
Computed from
- People not using improved sanitation facilities WHO/UNICEF Joint Monitoring Programme for Water Supply, Sanitation and Hygiene (2025) – processed by Our World in Data
- Land area FAOSTAT, Food and Agriculture Organization of the United Nations (FAO)
Statizoid computes this series; the underlying measurements belong to the publishers named above. The arithmetic is applied to every country and year where both inputs report, and nothing is estimated unless the page says so.
