Almost half of people drinking water from unprotected sources live in Sub-Saharan Africa, where the burden of collecting water lies mainly on women and girls, many of whom spend more than 30 minutes on each trip to collect water. (WWAP)

Sanitation

  • Worldwide, only 2.9 billion people (39% of global population) used safely managed sanitation services in 2015.  40% of these people lived in rural areas.
  • 2.1 billion people had access to “basic” sanitation services.
  • 2.3 billion (one out of every three people) lacked even a basic sanitation service—nearly 1 billion people (892 million) still practiced open defecation.
