This statistic represents the proportion of the world's population with access to drinking water sources from 1990 to 2010 and a projection for 2015, based on the quality of the drinking water source. In 1990, around 76 percent of the world's population had access to improved drinking water sources. According to the source, such water sources are those that are protected from outside contamination, particularly faecal matter.

* The figure for 2015 is a projection.
According to the source, improved drinking water sources are those that are protected from outside contamination, particularly faecal matter. However, some of these sources may not be adequately maintained and therefore may not actually provide “safe” drinking water. Thus, the number of people using such sources may have been over-estimated.
