This paper investigates internal migration and vulnerability to poverty in Tanzania. It examines whether migration reduced household vulnerability to poverty for a panel of households from the Kagera region over the period 2004-2010. The dataset allows the analysis of two samples of households: those with the same head in the periods considered and an enlarged network of split-off households. The potential endogeneity of migration is controlled by both matching methods and an exogenous variation. A severe drought in 2008-09 affected the areas of the country with a bimodal rain season, but not those with a unimodal rain season. It is thus possible to study the heterogeneity of migrants with respect to an unanticipated shock in the region of destination. The evidence shows that migration reduced vulnerability to basic needs and to food consumption poverty for families which experienced migration to unimodal regions. The results are consistent with migration as a risk management strategy by households.

坦桑尼亚的国内移民和贫困脆弱性

本文调查了坦桑尼亚的国内移民和贫困脆弱性。它研究了 2004 年至 2010 年期间，对于来自 Kagera 地区的一组家庭而言，移民是否降低了家庭对贫困的脆弱性。该数据集允许分析两个家庭样本：在所考虑的时期内具有相同户主的家庭和扩大的分离家庭网络。迁移的潜在内生性受匹配方法和外源变异控制。2008-09 年的严重干旱影响了该国双峰雨季的地区，但未影响单峰雨季的地区。因此，就目的地地区的意外冲击而言，研究移民的异质性是可能的。证据表明，对于经历过迁移到单峰地区的家庭来说，迁移减少了基本需求和粮食消费贫困的脆弱性。结果与迁移作为家庭风险管理策略一致。
