India launches data collection drive of up to a million residents in Mumbai's Dharavi slum

India's Adani Group is launching a data collection drive of up to one million residents in Asia's largest slum, Dharavi. The area was made famous by the Oscar-winning 2008 film 'Slumdog Millionaire'. Adani aims to redevelop the area with the help of the local government. It will be one of the world's biggest urban redevelopment projects. This is part of a broader plan to make Mumbai slum-free. Officials will scan documents and allocate each home with an identification number. Only residents who have lived in the slum before 2000 will be eligible for free homes. Rebecca Bundhun reports.
