Driven by the fact that there are too many local self-government units and organizations located in the region of „Dalmatia“; Croatia, in this work we analyze all those self-government units. The subject of this thesis is in fact the analysis of the existing condition within the local self-government units. The analysis of the units is conducted with all these factors in mind and carefully looked into: demographic indicators, socioeconomic indicators, traffic infrastructure and connections with their central functions. The methods that were used in this thesis include: analysis of various literatures and origins, analysis of statistical data and methods of visualization and analysis in GIS. The goal of this thesis is to recommend a new administrative and territorial structure for the region of „Dalmatia“. The main assumption is that the analysis will show how most of the current used units are too small and immensely dependant on the financial aid of the government and the county they are located in. After the analysis of the current administrative and territorial structure, a new administrative and territorial structure will be suggested; one that has fewer but larger sized local self-government units. The new administrative and territorial structure will be based on the self-government units which have satisfied all of the criteria during the analysis and the other units will be incorporated under those units accordingly based on distance and the traffic connections and infrastructures between the two.
