According to recent estimates, South Asia is facing a shortage of 38 million housing units, largely affecting low and middle-income households. It comes as no surprise that informal settlements, slums and squatters are growing in all major urban centers across Asia to supplement the demand from urban poor. India alone has 52,000 slums inhabited by 14 percent of its total urban population. Almost, 50 percent of total population in Karachi, i.e. 7.6 million persons, lives in Katchi-Abadis. Bangladesh has 2,100 slums and more than 2 million slum dwellers in Dhaka. Even in Afghanistan, 80 percent of residents in capital city, Kabul, live in informal settlements.
