Overview
- An estimated 2.1 billion people lack safely managed drinking water, including 106 million who still rely on untreated surface sources.
- Since 2015, 961 million people have gained access, raising global coverage from 68% to 74%, but the pace is insufficient to reach universal access.
- Sanitation and hygiene deficits remain severe, with 3.4 billion lacking safely managed sanitation, 354 million practicing open defecation, and 1.7 billion without basic hygiene, including 611 million with no facilities.
- Least developed countries carry the heaviest burden, where people are more than twice as likely to lack basic water and sanitation and over three times as likely to lack basic hygiene.
- Reliance on surface water fell by 61 million over the past decade and 154 countries have eliminated it for drinking, yet urban coverage has stagnated even as rural access improved.
