Thank you for the leads - Srinivas and Justin. Srinivas - I will look at the electoral rolls data - didn't think of that earlier. Thank you
Justin - apologies if I wasn't clear on my requirements earlier. I am personally interested in looking at socio-economic data: wages, poverty rates, labor markets information, access to credit, education status etc at a household level. I hope to use this data to see if I am able to make a convincing economic argument that the value of people living and working in Dharavi is greater (or can be made greater) than the value of the land value itself. At an aggregate level, reports indicate that the value of economic output from Dharavi is close to $600 million!! If this is true, then I want to test the hypothesis that increasing productivity through efficient design (which put capital in their hands or improves working conditions etc) will help people perceive Dharavi as less of a 'slum' and more of an industrial powerhouse for Mumbai.
The maps that you sent are extremely useful for the planners in my team though. If you come across anything else on similar lines- kindly request you to forward it as well. It will be of immense help.
Thank you so much again.
