A lot of attention has been given to the phenomenon of emigration in Croatia today due to their connection with the political and economic situation of a particular country. The research that has been conducted so far mainly focuses on economic factors as the most important causes of emigration. Although psychological factors are recognized as important factors associated with emigration, they are relatively neglected in research. The aim of this study was to examine the connection between personality traits of the Big Five Model, the aspiration for achievement, life satisfaction and socioeconomic status with the emigration of young people from Croatia. The importance of life satisfaction was studied by Greek philosophers who came to the conclusion that this concept is necessary for a good life and good functioning of the whole society. The second goal of this research was to examine the connection between the Big Five traits and life satisfaction of young people from Croatia. Young people from Croatia (N = 302) participated in this research. Two methods have been used to collect data: paper - pencil method and online method. Participants completed the following questionnaires: Intention to emigrate questionnaire, Mini - IPIP, Life satisfaction scale, Tendency towards achivement scale, and general data questionnaire. The results showed that personality and socioeconomic status are not the determinants of emigration from Croatia. Life satisfaction and aspiration for achievement were related to the purpose of emigration. All dimensions of personality, apart from Openness, were linked to the life satisfaction. This research provides guidelines for identifying the determinants of emigration in order to reduce this phenomenon, with the negative consequences it carries, and insight into the relationship between personality and life satisfaction of young people from Croatia.
