摘要：Spatial mobility of population is one of the basic demographic determinants. Regarding migration, Croatia is a dynamic country, which is characterized not only by external migration, but also by internal resettlement of population. In the last secular period the internal migration was caused by numerous socio-economic and political changes, but without a systematic concern about the country's demographic development. An uncontrolled migration lead to the demographic polarization of the country, to widening of the emigration areas, and narrowing if the immigration ones. So Croatia made a stride towards a new millennium with a polarized spatial distribution of population. Therefore, the country's demographic development policy should be based on a regional development concept, as one of the reasonable economic and demographic development alternatives.
