Over one billion people worldwide live in slums, including roughly one-third of India's poor population. In Mumbai, 55% of the over 14 million residents live in slums, occupying only 6-8% of the city's land. Despite challenges such as lack of water and sanitation, 72% of Mumbai's slum dwellers are literate, and their difficult living conditions force them to be resourceful and innovative. Improving access to basic amenities and redeveloping slum areas are priorities to address the problems faced by millions of India's urban poor.
