Majority of research on urban development perceive migration as internally homogeneous phenomenon that influences growth and spatial redistribution of population. This enables to identify certain general migration patterns, but understanding regularities and consequences requires looking at internal structure of migration. This paper aims to visualise the impact of selective migration to the population structures across multiple spatial scales and in a complex way taking Slovakia as the case study. By this means spatial patterns of migration are demonstrated in a more efficient way. The resulting maps show the impact of migration is selective at various spatial levels regarding age and educational attainment. In comparison with general migration, selective migration shows stronger spatial polarisation in Slovakia.

关于城市发展的大多数研究都将移民视为影响人口增长和空间再分配的内部同质现象。这可以确定某些一般的迁移模式，但是要了解规律性和后果，需要研究迁移的内部结构。本文旨在以斯洛伐克为例，以复杂的方式可视化选择性迁移对人口结构在多个空间尺度上的影响。通过这种方式，以更有效的方式展示了迁移的空间格局。生成的地图显示，在年龄和学历方面，移民在不同的空间层次上具有选择性。与一般迁徙相比，选择性迁徙在斯洛伐克表现出更强的空间极化。
