Clean Water and Sanitation

Having access to and using safe drinking water, sanitation, and handwashing is a basic human need.

Individuals not using these facilities increases the risk of disease and malnutrition and is attributed to millions of deaths each year.

The world has made significant progress in increasing their availability. In the past, infectious diseases were the leading cause of death in most countries. They’ve fallen dramatically in high and middle-income countries – partly due to increased usage of clean water and sanitation.

But there is still more work to do. It is still a major problem in low-income countries.

On this page, you can find all of our data on water, sanitation, and handwashing.
