Generation Z, which includes persons born between 1997 and 2012 (or between 1995 and 2010, depending on the author) and for whom the internet represents the main means of communication, is slowly entering the labor market, sparking interest in researching their attitudes towards saving and retirement. The subject of this thesis is to investigate the level of financial literacy of Generation Z in Croatia and their attitudes towards the pension system and retirement in general, with a comparison to selected countries. In addition to the Republic of Croatia, the paper analyzes the behavior patterns of Generation Z members in the United States, India, Germany, and Japan. The research objectives are to provide insight into Generation Z's awareness of the importance of the pension system and insurance, their thoughts on their financial future, and to highlight the factors that influence their attitudes and behaviors. The foundation for the primary research was data from secondary sources, including scientific papers, books, and websites of relevant institutions. The collected data was processed using methods of comparison, synthesis, and analysis. The primary research was conducted in the form of a survey questionnaire based on similar studies from the countries selected for comparison. The results of the research show, among other things, that most members of Generation Z are inclined to save and are interested in finances, but many of them do not have a financial plan for the future (old age) and do not believe that the Croatian pension system is sustainable.
