The impact of migration on the sizes, composition, and well-being of First Nations communities and the motivations that triggered such migrations have long been a topic of interest among researchers. Exploiting a new data source, linkages of consecutive censuses, this study aims to portray migration into and out of Indian reserves, with a focus on the Indigenous population. Between 2011 and 2016, migrations into and out of reserves resulted in net losses for reserves. These migratory losses, however, did not prevent the population on reserve to continue growing. From a socioeconomic point of view, migrations had a net positive impact on reserves by contributing to increase the proportions of individuals who are employed, with relatively high incomes or relatively high education. Looking at the determinants of migration, and taking advantage of a multilevel framework, it is found that migration into and out of reserves is multidimensional, being influenced by factors at both individual and community levels. Out-migration seems to be governed mainly by the propensity of individuals at certain stages of life to leave the reserve, permanently or not. In contrast, in-migration appears more influenced by reserves’ characteristics, and its prevalence varies greatly from one reserve to another.

移民对第一民族社区的规模、组成和福祉的影响以及引发此类移民的动机长期以来一直是研究人员感兴趣的话题。利用新的数据源，连续人口普查的联系，本研究旨在描绘进出印度保护区的移民，重点是土著人口。2011 年至 2016 年期间，进出储备的迁移导致储备的净损失。然而，这些迁徙损失并没有阻止保护区人口继续增长。从社会经济的角度来看，移民通过增加就业、收入相对较高或教育程度较高的个人的比例，对储备产生了净积极影响。从移民的决定因素来看，并利用多层次框架，发现迁入和迁出保护区是多层面的，受个人和社区层面因素的影响。外迁似乎主要取决于个人在生命的某些阶段是否永久离开保护区的倾向。相比之下，迁入似乎更多地受保护区特征的影响，其流行程度因保护区而异。
