La copertura con fonti sicure di acqua potabile per le popo-
lazioni rurali non è soddisfacente. Nel 2010, il 96% della
popolazione urbana utilizzava una fonte di acqua potabile
sicura, contro l’81% per cento della popolazione rurale.
In termini assoluti, a causa della crescita della popolazione,
il numero di persone senza acqua potabile nelle aree urbane
è effettivamente aumentato. Nelle zone rurali, invece, il nu-
mero di persone senza una fonte di acqua sicura è diminuito
da 1,1 miliardi nel 1990 a 653 milioni nel 2010.
Tuttavia, il divario tra aree urbane e rurali rimane ancora
ampio, con il numero di persone nelle zone rurali senza una
fonte d'acqua sicura cinque volte maggiore rispetto a quelle
urbane.

Coverage with improved drinking water sources for
rural populatio s is still lagging. In 201 , 96 per cent
of the urban population used an improved drinking
water source, compared with 81 per cent of the rural
population.
In absolute terms, because of population growth, the
number of people without an improved source in urban
areas actually increased. In rural areas, on the other
hand, the number of people without an improved
source of water decreased, from 1.1 billion in 1990 to
653 million in 2010. However, the gap between urban
and rural areas still remains wide, with the number of
people in rural areas without an improved water source
five times greater than in urban areas.
Poorer people in sub-Saharan Africa are at a disadvantag in access to drinking water
