This work concerns with the issue of social stratification, which is still very visible today. Croatia is one of those countries where this inequality of society is visible, which is why data related to poverty and well-being of individuals and the growing change in the distribution of society's wealth are being processed here, both in Croatia and also in other countries. The first part deals with social stratification, its meaning and general data in order to get better understanding what it is about, the second part talks about the stratification of society as far as Croatia is concerned, in which the analyzes of experts such as Šundalić, Mastilica and others divided the notion of social stratification into several parts in order to show the situation in which Croatia finds itself. The third and final section discusses the way in which stratification affects the lives of society, their members and how socialization, economic and health inequalities divide society in terms of their well-being to the families and groups in which they find themselves.
