Internal Migration in Indonesia: Descriptive Notes
The major reason for the small attention hitherto given to the study of internal migration in Indonesia has been the in adequacy of the relevant statistics. This is a pervasive prob lem for Indonesian demography; even the estimates of vital rates are open to considerable doubt. However, two new sources of in formation are now becoming available: the 1961 census and the 1964/65 National Sample Survey. When taken in conjunction with a number of other specialized studies, these provide a body of
... ta which give an overall picture of migratory patterns and make possible some checking for consistency. The outline of population movements in Indonesia is well known, though for the most part the quantities involved is not. The most obvious flow is that occasioned by the urbanization process; this is especially marked in the movement of people from rural Java to the large cities of that island, particularly Djakarta. The survey of urban migrants in Djakarta carried out by the Economic and Social Research Institute of the University of Indonesia in 19531 is still the only detailed treatment of this important phenomenon, and the general significance of its results is limited to some degree by the purposive selection of its sample. In his recent study of Djakarta,2 Castles has^ used data on ethnic groups from the 1930 census and the 1930 and 1961 data on birthplaces to estimate the 1961 ethnic composition of that city, and in the process has illustrated how much useful information can be extracted from such material by the judicious use of assumptions. Outmigration from Java under the govern ment's longstanding transmigration program, largely directed to Lampung province in Sumatra, has also received much attention, not least because of the sociological problems it has raised in the settlement areas. Studies proceeding from this concern in clude Kampto Utomofs discussion of a Javanese migrant community in Lampung3 and Widjojo Nitisastro's detailed population projec tions based on alternative assumptions of fertility, mortality, H.
