Access to piped water
Less than half of the poorest 20% urban households have access to a piped-onto-premises drinking-water source in Africa, Americas and Asia. Inequalities in access are particularly high in Africa where 75% of the richest 20% urban households have access compared to only 12% of the poorest 20% urban households.
Access to piped-onto-premises drinking-water among the poorest 20% urban households has nearly doubled in the Americas from 26% in 1990–1999 to 52% in 2000–2011. In Africa and Asia, too, there has been small increases of 4% and 5%, respectively, in access to piped-onto-premises water among the urban poorest 20% urban households. Among the richest 20% urban households in Americas and Asia, there has been a decline in use of piped-onto-premises water for drinking, which may partly be due to increased use of bottled water for drinking.
