828 million   The number of urban slum dwellers globally was 828 million in 2010.

Millennium Development Goal 7: Ensure environmental sustainability

Target 7D: By 2020, to have achieved a significant improvement in the lives of at least 100 million slum dwellers


Indicator 7.10: Proportion of urban population living in slums*

The number of urban residents living in slum conditions is now estimated at some 828 million, compared to 657 million in 1990 and 767 million in 2000.

From 2000 to 2010, the share of urban residents in the developing world living in slums declined from 39 per cent to 33 per cent. More than 200 million of these people gained access to either improved water, sanitation or durable and less crowded housing.

However, in absolute terms, the number of slum dwellers continues to grow, due in part to the fast pace of urbanization.

* The actual proportion of people living in slums is measured by a

proxy, represented by the urban population living in households with
at least one of the four characteristics:
A. lack of access to improved water supply;
B. lack of access to improved sanitation;
C. overcrowding (3 or more persons per room);
D. dwellings made of non-durable material.
