In light of possibilities and limitations of data from the Finnish population register, and the general demographic development of Finland, this paper illuminates the complex interrelation between internal migration and mortality. We explore the roles played by health selection, birth region, and migration as a potentially harmful event. A five per cent random sample from a longitudinal data file that contains deaths for a period of 24 years is used. The focus is on people aged 40-59 years living in Southern Finland, who are defined by birth region and time since immigration. We find some indications of a healthy-migrant effect, but also that migrants may have integration difficulties or that they are negatively selected with regard to health behaviours and lifestyles. In line with previous studies on Finland, birth region is found to be a very decisive mortality determinant.
鉴于芬兰人口登记数据的可能性和局限性，以及芬兰的总体人口发展情况，本文阐明了国内迁移与死亡率之间的复杂相互关系。我们探讨了健康选择、出生地区以及迁移作为潜在有害事件所起的作用。使用了一个纵向数据文件中24年期间死亡情况的5%随机样本。重点关注居住在芬兰南部、年龄在40至59岁之间的人群，这些人群由出生地区和移民后的时间来界定。我们发现了一些健康移民效应的迹象，但也发现移民可能存在融入困难，或者在健康行为和生活方式方面受到负面选择。与之前对芬兰的研究一致，出生地区被发现是一个非常决定性的死亡率决定因素。
