AGE AT MIGRATION, DURATION OF RESIDENCE, AND FERTILITY AMONG FEMALE MIGRANTS INTO JAVA

Java Island has become main destination for inter-regional migrants in Indonesia for decades. Previous studies has shown that migration can be expected to have a strong effect on fertility behavior of female migrants. The objective of this study is to examine fertility patterns of internal female migrants into Java Island. The generalized poisson regression models are used to investigate the socialization, the disruption, and the adaptation hypotheses in explaining the fertility differences between migrants and non-migrants. This study finds that the fertility rate for migrants is higher relative to the non-migrants. The analysis shows that first, there is a fertility assimilation process in migration into Java Island with fertility increasing gradually with age at migration. Second, there is a fertility disruption process in migration into Java Island with short-term fertility-lowering-effect of migration event. However, this study find no evidence on fertility adaptation process in migration into Java Island.
