The UN explains: "Clean water is a basic human need, and one that should be easily accessible to all. There is sufficient fresh water on the planet to achieve this. However, due to poor infrastructure, investment and planning, every year millions of people — most of them children — die from diseases associated with inadequate water supply, sanitation and hygiene."
The charts below summarise progress towards improved water and sanitation access. More details can be found in the Our World in Data entry on Water Access, Resources and Sanitation.
The UN has defined 8 Targets and 11 Indicators for SDG 6. Targets specify the goals and Indicators represent the metrics by which the world aims to track whether these Targets are achieved. Below we quote the original text of all Targets and show the data on the agreed Indicators.
