Write a note on the chawls of Bombay.

Chawls were multi-storeyed structures which were built in the 'native' parts of the town. These houses were owned by private landlords who rented these chawls to migrant workers. Each chawl was divided into smaller one-room tenements which had no private toilets. Many families could reside at a time in a tenement. 80 % of Bombay's population resided in these chawls.
