Malaya has a plural society in which Malays form 49·8 per cent of the total population, Chinese 37·2 per cent and Indians 11·2 per cent. Apart from this racial diversity, there is the added fact that the Malays tend to live in the rural areas whereas the immigrant groups tend to live in the urban areas or on the plantations, and only to a much lesser extent in the rural areas. For example, of the rural population of Malaya, Malays form 70 per cent, Chinese 17 per cent and Indians 11 per cent. In the urban areas of Malaya, Malays make up 23 per cent of the population, Chinese 65 per cent and Indians 10 per cent. In 1957 the average annual income of the adult male in the Malay community was $1,463, as against $3,223 in the Chinese community and $2,031 in the Indian. From these figures it is clear that the Malays have lagged behind the immigrant communities in respect of economic development.
