MDG 7: water and sanitation
Proportion of population using an improved drinking-water source
Target: 50% reduction in proportion of people without sustainable access to safe drinking-water
The indicator monitors access to improved water sources based on the assumption that improved sources are more likely to provide safe water. Unsafe water is the direct cause of many diseases.
It is the ratio of the number of people or households who use piped water, public taps, bore-hole or pump, protected well, protected spring or rainwater to the total population or total households expressed as a percentage. Improved water sources do not include unprotected wells and springs.
Situation in SEAR
As shown in the bar graph and radar chart below, seven out of 11 SEA Region countries have already achieved their 2015 targets of increase in proportion of population using an improved source of drinking water. The remaining four are on track to achieve on or before 2015 provided they continue with their current annual rates of progress on this indicator.
