Looking back on 25 years of water, sanitation and hygiene monitoring, this report provides a comprehensive assessment of progress since 1990. The Millennium Development Goal target for drinking water was achieved in 2010, but, in 2015, 663-million people still lack improved drinking water sources. The world has missed the sanitation target by almost 700-million people, with 2.4-billion still lacking improved sanitation facilities and 946-million practicing open defecation.
