In respect to planned and already made preliminary actions it is expected to carry out planned research without some major difficulties. The researchers are convinced that they will respond to questions put and to confirm or confute starting assumption. In contemporary internal migration in Croatia two special types can be distinguished. One type represents the continuation of traditional migration flows within Croatia between its emigrational, primarily mountain, island and rural areas towards main centres of macroregions and partly towards municipal centres, while the second type is the result of war agreesion against Croatia. In the first case we speak about a process within regular demographic development, while war, i.e. forced migration, among other factors, defined present demographic development irregular.
Adriatic islands are a characteristic area of long-lasting emigration.
The consequence of one-way mechanical movement is depopulation, and in some places the extinction of whole settlements. The programme of demographic research of the island area fits, for the most part, into the concept of the National programme of islands' development. The research should offer comprehension of total demographic war losses of the Croatian Podunavlje and it should propose, with the aim at complete socio-political and economic development, models of return, autochtonous biological renewal and settling. Research application Research results will represent original cognitions on demographic condition and processes in the areas of disformed demographic balance caused by lasting emigration and forced war migration, and these cognitions, besides contributing to the fund of knowledge on demographic processes in specific areas, will represent a solid foundation on which political, economic and other proceedings of particular bodies and departments should be based. Without regard to the fact that some other institutions can define similar research objective as this research group, its previous research experience as well as many published scientific works point out that the result of this reseach will contribute to the increase of the general fund of knowledge on internal migration in Croatia and help to the realization of the main strategic goal of our state and this is the establishment of sovereignty on its whole territory.
