As we can see above, the access to safe water is unequal distributed in the world. In Sub-Saharan Africa fewest people have access to safe drinking water. But also in South Asia and Latin America & Caribbean a bigger part of the human population is suffering from water scarcities.

The biggest difference between the regional average and the lowest is within the Developed Countries. Whereas the group average is that 99% of the population have access to safe drinking water, in Romania it applies only for 57%.
