We apply multilevel methods to data from Mexico to examine how village migration patterns affect infant survival outcomes in origins. We argue that migration is a cumulative process with varying health effects at different stages of its progression, and test several related hypotheses. Findings suggest higher rates of infant mortality in communities experiencing intense U.S. migration. However, two factors diminish the disruptive effects of migration: migradollars, or migrant remittances to villages, and the institutionalization of migration over time. Mortality risks are low when remittances are high and decrease as migration becomes increasingly salient to livelihoods of communities. Together, the findings indicate eventual benefits to all infants, irrespective of household migration experience, as a result of the development of social and economic processes related to U.S. migration.
我们将多层次方法应用于来自墨西哥的数据,以研究村庄的移民模式如何影响原住地的婴儿生存结果。我们认为,移民是一个累积过程,在其发展的不同阶段对健康有不同影响,并检验了几个相关假设。研究结果表明,在美国移民密集的社区,婴儿死亡率较高。然而,有两个因素可减轻移民的破坏影响:即“移民美元”,也就是移民给村庄的汇款,以及随着时间推移移民的制度化。当汇款较高时,死亡风险较低,且随着移民对社区生计的重要性日益增加,死亡风险会降低。这些研究结果共同表明,由于与美国移民相关的社会和经济进程的发展,所有婴儿最终都会受益,无论其家庭的移民经历如何。
