Thousands of people move to Mumbai from smaller towns or the countryside. They have many reasons for moving. Some reasons are bad things that push them out of their homes in the countryside. Others are good things that pull them to the city. Can you sort out these push and pull reasons for moving by dragging them into the table?
The countryside or a big city - where would you prefer to live? Why?
Look at this picture of a street in Mumbai - How are people making a living? Who earns the most? Do they need special skills? Who do you think is happiest with their job?
Many people who arrive from outside Mumbai don't have the skills to get good jobs in the city. Why do you think that is? Instead, they find poorly paid jobs, working as servants or street cleaners.
Some of the very poorest people become 'rag-pickers'. They either collect the rubbish in the streets or sort through rubbish tips to look for anything that could be re-used or re-sold.
Two thousand women are members of a rag pickers' group called Parisar Vikas. Together, they learn ways to clean up the city. They earn 75 rupees (about 90p) a day, which is more than a lot of other people earn in India. And these women are proud to be able to support their families.
For women in the Parisar Vikas group the work is dangerous if the rubbish isn't sorted properly. Sometimes, they cut their hands because the waste has sharp objects like glass or even razor blades in it.
