In Indonesia the redistribution problem is at least as important as high fertility. Since the beginning of the 20th Century Indonesia has faced an imbalance of population distribution with more than 60 percent of the population concentrated in Java, containing only 6.9 percent of the total area of Indonesia. The inequality of distribution of population among areas has created problems of over population in Java with all its economic, social, and cultural consequences, and under population outside Java. Nothing would seem more natural than to attempt to solve this problem of Java's over population than with a large scale migration. The population migration which has begun many years ago caused the heterogeneity of people (based on province of birth) who lived in several areas of Indonesia. From the 1971 and 1980 Population Censuses, the distribution of the lifetime migrants in several provinces in Indonesia can be detected.
