Had the partition of India somehow been avoided (for instance, having Jinnah's tuberculosis be discovered--which could have resulted in Britain engaging in delaying tactics until Jinnah would have died in the hope that whoever will succeed him as leader of the Muslim League would be more willing to compromise than Jinnah was), what would internal migration in a united India look like?

Obviously there would not have been the extremely massive population movements that occurred as a result of Partition (specifically Hindus and Sikhs to India and Muslims to Pakistan--though with a lot of Indian Muslims staying in India instead of moving to Pakistan). However, what internal migration would there have been in a united India? Which regions would have received large numbers of domestic migrants and which regions would have experienced a continued population exodus as a result of there being less opportunities and a worse quality of life there?

BTW, what regions in India get a lot of internal migration in real life? In Pakistan's case, I'm assuming that the answer is Karachi, Punjab, and perhaps Islamabad as well, but what about for India? Also, what about for Bangladesh?
