This paper is the first to examine to what extent ethnicity affects ever migrating and the number of migrations across the lifespan for the case of internal migration in Indonesia. We use all five waves of the Indonesia Family Life Survey (IFLS) to study migration behaviour of respondents belonging to some of the largest ethnic groups in Indonesia. Our logistic regression results show that the Minangkabau, Betawi, Madurese, Balinese, Buginese and Makassarese, and Sasak, Bima and Dompu are less likely to ever migrate than the Javanese. Using only migrants and controlling for the first migration and other characteristics, truncated negative binomial regression results show that, in comparison with the Javanese, the Minangkabau and Banjarese have a higher expected number of migrations while the numbers are lower for the Betawi and Balinese. Thus, ethnicity contributes to ever migrating as well as the number of migrations, but we find that the differences between the ethnic groups diminish for the latter. These results also point out that a higher likelihood of ever migrating does not always correspond with a higher number of migrations, highlighting the importance of studying migration count to complement the study of migration as a one-time event.
本文首次探讨了在印度尼西亚国内移民的情况下，种族在多大程度上影响终身移民经历以及移民次数。我们利用印度尼西亚家庭生活调查（IFLS）的全部五轮数据，研究了印度尼西亚一些最大种族群体中受访者的移民行为。我们的逻辑回归结果表明，与爪哇族相比，米南卡保族、巽他族、马都拉族、巴厘族、布吉族和望加锡族，以及萨萨克族、比马族和栋布族终身移民的可能性较小。仅使用移民样本并控制首次移民及其他特征后，截断负二项回归结果显示，与爪哇族相比，米南卡保族和班贾尔族的预期移民次数较多，而巽他族和巴厘族的移民次数较少。因此，种族既影响终身移民经历，也影响移民次数，但我们发现，种族群体之间在移民次数上差异较小。这些结果还指出，终身移民可能性较高并不总是对应着较多的移民次数，这凸显了研究移民次数以补充一次性移民事件研究的重要性。
