The purpose of this thesis was to study history and problems of emigration waves of the population of the Republic of Croatia that have been ongoing for decades. The thesis starts from the fact that poor economic and/or political situations, present before the beginning of World War Ⅰ, have been forcing Croatian people to leave their homeland. Demographic measures of the Fourteenth Government of the Republic of Croatia and communication of those measures have been reviewed. The thesis also contains a review about media announcements dealing with the resignation of Marin Strmota, the former State secretary of the Ministry of Demographics, Family, Youth and Social Policy. For the purposes of writing this thesis, a survey was conducted. The survey’s main goal was to examine the mass emigration causes of the population of Croatia. An effort has been made to examine from which Croatian regions the majority of the population emigrates, which countries they emigrate to, the reasons for emigration, and whether examinees find the quality of life better in the emigration than in Croatia. A quantitative method was used for the research; a survey that included 1.048 Croatian emigrants was conducted. The analysis showed that the most significant reason for emigration was hope for a better future for their children and themselves. A great number of examinees stated that they emigrated because of various political reasons, but also due to small incomes and unemployment. Most of the examinees emigrated from Eastern Croatia.
