The United Nations report says the number of slum dwellers will pass the 1bn mark in 2007, which means that one in three city residents will live in inadequate housing with no or few basic services. It adds that urban growth and slum expansion rates are nearly identical in some regions, and that the world's urban poor are rapidly becoming one of its biggest problems.
The number of slum dwellers will pass the 1 billion mark!? Ya ilahi! There are approx 6.6 billion ppl living on Earth today. That's a large percentage of the population.
