Geography of elections in Republic of Croatia’s geographic and scientific community is poorly represented and developed. The reason behind it may be a relatively brief democratic tradition and insufficient number of electoral cycles which lead to formation of certain factors that influence the spatial distribution of votes. Another reason could be the division of the political scene of Croatia, which is more affected by a political party’s ideological values than by the economical questions these parties represent, along with factors such as gender, age, religion, etc. The factors analysed in this paper have less and less influence over the spatial distribution of votes, however, there is still a certain division present in accordance with these factors. In this paper, the analysis focuses on the influence of urban/rural differences and population’s income regarding spatial distribution of votes of Social Democratic Party (Socijaldemokratska partija - SDP) and Croatian Democratic Union (Hrvatska demokratska zajednica - HDZ). The reason for selection of these factors for the analysis of this paper is the aforementioned parties’ constant and interchangeable rule in Croatia over the last 30 years (along with different coalition partners from time to time), as well as their domination regarding parliamentary seats in the Croatian Parliament. The results of the analysis show that, even though the influence of urban/rural differences and population’s income is not that strong, most votes for SDP tend to come from more economically developed areas, while HDZ tends to get more votes from less developed areas. Similarly, voters from larger urban settlements tend to vote for SDP, while the voters living in rural areas are more likely to vote for HDZ.
