Where did the workers come from to work in factories in India?

With the expansion of factories, the demand for workers increased. In 1901, there were 584,000 workers in Indian factories. By 1946, the number increased to 2,456,000. This large number of workers came from the places as mentioned below:
(l) In most industrial regions the workers came from the districts around because peasants and artisans who found no work in the village went to the industrial centres in search of work. For example in the Bombay cotton industries in 1911, over 50 per cent workers came from the neighbouring district of Ratnagiri.
(ii) Sometimes, worker’s carne from distant places in search of work in the mills. For example, many workers from the United Provinces went to work in the textile mills of Bombay and in the jute mills of Calcutta.
