The Global Sanitation Crisis.
• 3.4 billion people still live without safely managed sanitation services — that’s nearly half the world’s population. (WHO/UNICEF, 2025) • 354 million people still practise open defecation , increasing the risk of disease and harm, especially for women and girls. (WHO/UNICEF, 2025) • Only 58% of the global population use a safely managed sanitation service — which means an improved toilet that is not shared, and has excreta safely disposed of in situ or transported and treated offsite. (WHO/UNICEF, 2025)
