Sumatran population growth and influences Sumatra, Indonesia's large western Outer Island region, had general, urban and rural rates of population growth during 1961-71 as much as 50% or higher than those for the remainder of Indonesia. The rapid population growth in Sumatra, continuing into the later 1970s, has been associated with a variety of influences. Among these were: New or improved economic activities encompassing large-scale extraction of crude oil, natural gas, tin, bauxite, and forest products; some coal mining; continued fisheries, commercial small-holder and estate types of agriculture; and new or expanded manufacturing. Large-scale transmigration, in-migration from elsewhere in Indonesia other than Java and Bali, and intramigration within Sumatra have led to increased populations and densities in at least five major areas. The southern area of Lampung Province and to a lesser extent eastern South Sumatra have had notable growth from transmigration flows; several coastal plains areas in Aceh, North Sumatra, West Sumatra, Riau, and Jambi provinces, from upland to lowland or other in- and intra-migration flows. Traditional ethnic, religious, and regional linkages within a predominantly rural village system have remained strong. These cultural conditions provide a background for understanding the continuing overwhelming rural character of Sumatra's people. Although urban growth was more rapid than rural growth in Sumatra during 1961-71, most of this urban growth was concentrated in and around a few relatively large urban centres; the remainder of the urban growth was in the many other urban places, most having the aspect of overgrown villages. Differential growth rates for total, rural, and urban populations were associated with differing perceptions at local, provincial, Sumatra-wide, or national levels — of the areas having the best opportunities for improved living. With a few exceptions, Sumatra's upland areas have lost large numbers of people to near-by and only recently highly accessible lowlands. Small, but crucially important, numbers of ambitious and more highly educated people have left Sumatra for Jakarta or other areas of actual and perceived greater economic opportunity. In 1971 the sharply contrasting and increasing population densities of Sumatra emphasized several areas of greater economic development on the one hand; areas of continued limited accessibility or economic activities oil the other. If trends of the 1961-71 decade persist, the 1981 Indonesian census results for Sumatra should indicate increased populations and densities, particularly in the southern Lampung area of agricultural inflow and in the lowlands around Sumatra's large cities which also should continue to have sizeable population increases.
