Sanitation
In 1990 63 percent of the people living in low- and middle-income economies lacked access to a flush toilet orother form of improved sanitation. By 2010 the access rate had improved by 19 percentage points to 44 percent. The situation is worse in rural areas, where 57 percent of the population lack access to improved sanitation. The large urban-rural disparity, especially in Sub-Saharan Africa and South Asia, is the principal reason the sanitation target of the Millennium Development Goals will not be achieved.
