Malaya at the start of the twentieth century, in common with much of the non-European world, had a peasant economy upon which a highly capitalized export economy was being grafted. The main export in the 19th century was tin, but tin took second place to rubber by 1916. There was, as is characteristic of export economies, a great disparity between the resources, particularly capital, available to the indigenous peasant population and those available to the export sector. There were, however, distinctive features to the Malayan situation, the most important being that the capitalist export economy did not draw on the subsistence sector for produce, labour, or food; food was imported, as was the labour used in mining and on estates. The output from rubber and coconut smallholdings, many of which were Malay owned, augmented Malaya's exports, particularly after 1910, but mines and estates operated independently from the indigenous rural population. There was a high level of coincidence between ethnic groupings and occupational specializations, and the economic division between peasant cultivation and the export sector also marked the ethnic division between Malays and non-Malays. Because the colonial administration nominally held power on behalf of the Malay population, the question of the welfare and economic role of the Malays had political implications disproportionate to its economic importance.
