The purpose of this paper is to investigate the quality of life in the Republic of Croatia, that is how satisfied the residents are with living conditions in the country. Respondents participating in the study have different age, and ultimately the goal is to make a comparison according to gender and age classification of the population of the Republic of Croatia to determine how good life is among the younger population and how much among the elderly. The survey was conducted via the Internet using the Google Forms tool. Before the presented results, it was first theoretically explained what the quality of life is, what impact it has on people, or how much human needs are fulfilled, mostly primary ones. Also, three key phases that had an impact on the formation of different definitions of quality of life are listed. Subjective and objective indicators, which are one of the most important criteria when measuring quality of life, are presented in more detail. The paper also presents the quality of life in Croatia by individual regions, that is regional differences between 20 Croatian counties and the City of Zagreb, which has both city status and county status. In addition to the above, the quality of life between Croatia and other EU member states was also compared. The results of the fourth European Quality of Life Survey (EQLS) conducted in 2016 by Eurofound are presented. The results of the conducted research show that the quality of life in the Republic of Croatia is at a relatively low level, and the respondents of the younger age group are much more dissatisfied with the quality of life than the respondents of the older age group.
