If you download this second file, please note: The MDG drinking water and sanitation target is a global target. However, for advocacy purposes it has been common practice to assess progress at regional as well as country level using the same formulation of the global target. Several papers have pointed out that countries starting out with a low baseline coverage in 1990 and those facing high population growth face a much greater challenge using the global formulation of the target than countries starting out with a high baseline coverage. The application of the same progress assessment to all countries, therefore works to the disadvantage of the least developed countries, making it much harder for them to reach or even be on track for meeting the MDG drinking water and sanitation target.
