The fraction of Indians in Malaya’s population rose very sharply in the decades between 1901–1921, from just 6 per cent to 15 per cent, as rubber planting expanded and inflows were at their peak. But the Indian share of the population fell after 1931 and was just 11 per cent by 1947, as many Indian plantation workers were repatriated as a result of the rise in unemployment over the Great Depression years (Figure 1).
Beyond the plantations, Indians were recruited, inter alia, for public works, as police and guards, and also to serve in the lower ranks of the colonial bureaucracy. Most came from Tamil areas in south India. They were considered to be more accustomed to British rule, more amenable to discipline than the Chinese, and more willing to work for low wages. Access to low cost Indian labour migration helped ensure the rubber industry’s spectacular growth and profitability. Since there was work for wives and older children on the rubber estates, Indian migration included whole families. But low wages, indebtedness, poor social status, and physical isolation kept estate Indians apart and they tended to exercise little influence on Malayan society.
