total (and largely informal economy) turnover is estimated to be between 500 million, and 650 million per year, to over 1 billion per year.

A few travel operators offer guided tours through Dharavi, showing the industrial and the residential part of Dharavi and explaining about the problems and challenges Dharavi is facing.
