During the early postwar years up to 1957, the three main races in Malaya - Malays, Chinese, and Indians - experienced some differences in their levels of fertility. The lowest fertility was recorded among the Malays, with Chinese and Indian fertility about 5 percent and 10 percent higher, respectively. The comparatively low fertility of the Malays was owing to the exceptionally high rate of divorce, which meant unstable marriages and shorter periods of exposure to the risk of childbearing.A fairly well-defined pattern of state differences in fertility levels is found to exist in Malaya. Briefly, fertility was on the high side in the northern states of Johore, Malacca, and Negri Sembilan, and on the low side in the northern states of Penanq, Kelantan, Perlis, Kedah, and Trengganu, with the central states of Perak, Selangor, and Pahang in the intermediate position.The usual rural-urban fertility differentials are seen to prevail in Malaya as a whole and in the smaller units at state levels. Finally, the three main races registered higher fertility in rural areas, and the greatest gap between rural and urban rates prevailed among the Chinese.

The first section of this paper is devoted to an analysis of some theoretical aspects of the Chinese system of reckoning ages, and the second section offers a method of collecting the age statistics of a Chinese population: A discussion of the errors found in the age returns and the unsuccessful measures taken to eradicate these errors in the Malayan censuses conducted prior to1957 leads to an appraisal of the method of collecting Chinese age data in the 1957 census.

Abstract The Murut tribe of Sabah (formerly North Borneo) numbered 30,300 in 1921, decreased to 18,700 in 1951, and increased again to 22,100 in 1960. In 1951, the tribe was a small diminishing section of a slowly growing population; in 1960 it was increasing itself, and the growth rate of the whole population had shot up. Marked variations in the age structures of the Murut and other indigenous tribes accompanied these changes. Between 1920 and 1960 several investigators attempted to explain the decline, but could not show why only one tribe was failing to hold its own among many others which were increasing. Their findings are summarized, and unpublished data from the 1960 census are given which suggest that increasing contacts with the rest of the population, earlier thought to be an important contributor to the decline, were probably the means of saving the Murut from extinction.
The particular agricultural adaptation we have been considering is the ultimate determinant of the presence of malaria parasites in the intracellular environment of the human red blood cell. This change in the cellular environment is deleterious for normal individuals, but individuals with the sickle-cell gene are capable of changing their red-cell environment so that intense parasitism never develops. Normal individuals suffer higher mortality rates and lower fertility rates in a malarious environment than individuals with the sickle-cell trait do, so the latter contribute proportionately more people to succeeding generations.
